# Elastic Defend Integration

Elastic Defend provides organizations with prevention, detection, and response capabilities with deep visibility for EPP, EDR, SIEM, and Security Analytics use cases across Windows, macOS, and Linux operating systems running on both traditional endpoints and public cloud environments. ​​Use Elastic Defend to:

- **Prevent complex attacks** - Prevent malware (Windows, macOS, Linux) and ransomware (Windows) from executing, and stop advanced threats with malicious behavior (Windows, macOS, Linux), memory threat (Windows, macOS, Linux), and credential hardening (Windows) protections. All powered by [Elastic Labs](https://www.elastic.co/security-labs/) and our global community.
- **Alert in high fidelity** - Bolster team efficacy by detecting threats centrally and minimizing false positives via extensive corroboration.
- **Detect threats in high fidelity** - Elastic Defend facilitates deep visibility by instrumenting the process, file, and network data in your environments with minimal data collection overhead.
- **Triage and respond rapidly** - Quickly analyze detailed data from across your hosts. Examine host-based activity with interactive visualizations. Invoke remote response actions across distributed endpoints. Extend investigation capabilities even further with the Osquery integration, fully integrated into Elastic Security workflows.
- **Secure your cloud workloads** - Stop threats targeting cloud workloads and cloud-native applications. Gain real-time visibility and control with a lightweight user-space agent, powered by eBPF. Automate the identification of cloud threats with detection rules and machine learning (ML). Achieve rapid time-to-value with MITRE ATT&CK-aligned detections honed by Elastic Security Labs. 
- **View terminal sessions** - Give your security team a unique and powerful investigative tool for digital forensics and incident response (DFIR), reducing the mean time to respond (MTTR). Session view provides a time-ordered series of process executions in your Linux workloads in the form of a terminal shell, as well as the ability to replay the terminal session.

**Installation guide**

| dns.question.type | The type of record being queried. | keyword |
| ecs.version | ECS version this event conforms to. `ecs.version` is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
| elastic.agent | The agent fields contain data about the Elastic Agent. The Elastic Agent is the management agent that manages other agents or process on the host. | object |
| elastic.agent.id | Unique identifier of this elastic agent (if one exists). | keyword |
| event.action | The action captured by the event. This describes the information in the event. It is more specific than `event.category`. Examples are `group-add`, `process-started`, `file-created`. The value is normally defined by the implementer. | keyword |
| event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
| event.code | Identification code for this event, if one exists. Some event sources use event codes to identify messages unambiguously, regardless of message language or wording adjustments over time. An example of this is the Windows Event ID. | keyword |
| event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
| event.dataset | Name of the dataset. If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from. It's recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name. | keyword |
| event.hash | Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity. | keyword |
| event.id | Unique ID to describe the event. | keyword |
| event.ingested | Timestamp when an event arrived in the central data store. This is different from `@timestamp`, which is when the event originally occurred.  It's also different from `event.created`, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: `@timestamp` < `event.created` < `event.ingested`. | date |
| event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
| event.module | Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), `event.module` should contain the name of this module. | keyword |
| event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense. | keyword |
| event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
| event.risk_score | Risk score or priority of the event (e.g. security solutions). Use your system's original value here. | float |
| event.sequence | Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regardless of the timestamp precision. | long |
| event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`. | long |
| event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |

If the character device for the controlling tty is the same as stdin and stderr for the process, the process is considered interactive. Note: A non-interactive process can belong to an interactive session and is simply one that does not have open file descriptors reading the controlling TTY on FD 0 (stdin) or writing to the controlling TTY on FD 2 (stderr). A backgrounded process is still considered interactive if stdin and stderr are connected to the controlling TTY. | boolean |

The implementation of this is specified by the data source, but some examples of what could be used here are a process-generated UUID, Sysmon Process GUIDs, or a hash of some uniquely identifying components of a process. Constructing a globally unique identifier is a common practice to mitigate PID reuse as well as to identify a specific process over time, across multiple monitored hosts. | keyword |

Details under `process.*` like `pid` would be the same under `process.group_leader.*` The same applies for both `process.session_leader` and `process.entry_leader`. This field exists to the benefit of EQL and other rule engines since it's not possible to compare equality between two fields in a single document. e.g `process.entity_id` = `process.group_leader.entity_id` (top level process is the process group leader) OR `process.entity_id` = `process.entry_leader.entity_id` (top level process is the entry session leader) Instead these rules could be written like: `process.group_leader.same_as_process: true` OR `process.entry_leader.same_as_process: true` Note: This field is only set on `process.entry_leader`, `process.session_leader` and `process.group_leader`. | boolean |

| threat.indicator.url.domain | Domain of the url, such as "www.elastic.co". In some cases a URL may refer to an IP and/or port directly, without a domain name. In this case, the IP address would go to the `domain` field. If the URL contains a literal IPv6 address enclosed by `[` and `]` (IETF RFC 2732), the `[` and `]` characters should also be captured in the `domain` field. | keyword |
| threat.indicator.url.extension | The field contains the file extension from the original request url, excluding the leading dot. The file extension is only set if it exists, as not every url has a file extension. The leading period must not be included. For example, the value must be "png", not ".png". Note that when the file name has multiple extensions (example.tar.gz), only the last one should be captured ("gz", not "tar.gz"). | keyword |
| threat.indicator.url.fragment | Portion of the url after the `#`, such as "top". The `#` is not part of the fragment. | keyword |

The `exists` query can be used to differentiate between the two cases. | keyword |
| threat.indicator.url.registered_domain | The highest registered url domain, stripped of the subdomain. For example, the registered domain for "foo.example.com" is "example.com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk". | keyword |
| threat.indicator.url.scheme | Scheme of the request, such as "https". Note: The `:` is not part of the scheme. | keyword |
| threat.indicator.url.subdomain | The subdomain portion of a fully qualified domain name includes all of the names except the host name under the registered_domain.  In a partially qualified domain, or if the the qualification level of the full name cannot be determined, subdomain contains all of the names below the registered domain. For example the subdomain portion of "www.east.mydomain.co.uk" is "east". If the domain has multiple levels of subdomain, such as "sub2.sub1.example.com", the subdomain field should contain "sub2.sub1", with no trailing period. | keyword |
| threat.indicator.url.top_level_domain | The effective top level domain (eTLD), also known as the domain suffix, is the last part of the domain name. For example, the top level domain for example.com is "com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk". | keyword |

### file

#### Exported fields

| Field | Description | Type |
|---|---|---|
| @timestamp | Date/time when the event originated. This is the date/time extracted from the event, typically representing when the event was generated by the source.

| destination.geo.country_name | Country name. | keyword |
| destination.geo.location | Longitude and latitude. | geo_point |
| destination.geo.name | User-defined description of a location, at the level of granularity they care about. Could be the name of their data centers, the floor number, if this describes a local physical entity, city names. Not typically used in automated geolocation. | keyword |
| destination.geo.postal_code | Postal code associated with the location. Values appropriate for this field may also be known as a postcode or ZIP code and will vary widely from country to country. | keyword |
| destination.geo.region_iso_code | Region ISO code. | keyword |
| destination.geo.region_name | Region name. | keyword |
| destination.geo.timezone | The time zone of the location, such as IANA time zone name. | keyword |
| ecs.version | ECS version this event conforms to. `ecs.version` is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
| event.Ext | Object for all custom defined fields to live in. | object |
| event.Ext.correlation | Information about event this should be correlated with. | object |
| event.Ext.correlation.id | ID of event that this event is correlated to, e.g. quarantine event associated with an unquarantine event | keyword |
| event.action | The action captured by the event. This describes the information in the event. It is more specific than `event.category`. Examples are `group-add`, `process-started`, `file-created`. The value is normally defined by the implementer. | keyword |
| event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
| event.code | Identification code for this event, if one exists. Some event sources use event codes to identify messages unambiguously, regardless of message language or wording adjustments over time. An example of this is the Windows Event ID. | keyword |
| event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
| event.dataset | Name of the dataset. If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from. It's recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name. | keyword |
| event.hash | Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity. | keyword |
| event.id | Unique ID to describe the event. | keyword |
| event.ingested | Timestamp when an event arrived in the central data store. This is different from `@timestamp`, which is when the event originally occurred.  It's also different from `event.created`, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: `@timestamp` < `event.created` < `event.ingested`. | date |
| event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
| event.module | Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), `event.module` should contain the name of this module. | keyword |
| event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense. | keyword |
| event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
| event.sequence | Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regardless of the timestamp precision. | long |
| event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`. | long |
| event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |
| file.Ext | Object for all custom defined fields to live in. | object |
| file.Ext.device.bus_type | Bus type of the device, such as Nvme, Usb, FileBackedVirtual,... etc. | keyword |

| dll.pe.product | Internal product name of the file, provided at compile-time. | keyword |
| ecs.version | ECS version this event conforms to. `ecs.version` is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
| event.action | The action captured by the event. This describes the information in the event. It is more specific than `event.category`. Examples are `group-add`, `process-started`, `file-created`. The value is normally defined by the implementer. | keyword |
| event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
| event.code | Identification code for this event, if one exists. Some event sources use event codes to identify messages unambiguously, regardless of message language or wording adjustments over time. An example of this is the Windows Event ID. | keyword |
| event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
| event.dataset | Name of the dataset. If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from. It's recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name. | keyword |
| event.hash | Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity. | keyword |
| event.id | Unique ID to describe the event. | keyword |
| event.ingested | Timestamp when an event arrived in the central data store. This is different from `@timestamp`, which is when the event originally occurred.  It's also different from `event.created`, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: `@timestamp` < `event.created` < `event.ingested`. | date |
| event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
| event.module | Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), `event.module` should contain the name of this module. | keyword |
| event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense. | keyword |
| event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
| event.sequence | Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regardless of the timestamp precision. | long |
| event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`. | long |
| event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |

#### Exported fields

| Field | Description | Type |
|---|---|---|
| @timestamp | Date/time when the event originated. This is the date/time extracted from the event, typically representing when the event was generated by the source. If the event source has no original timestamp, this value is typically populated by the first time the event was received by the pipeline. Required field for all events. | date |
| agent.id | Unique identifier of this agent (if one exists). Example: For Beats this would be beat.id. | keyword |
| agent.type | Type of the agent. The agent type always stays the same and should be given by the agent used. In case of Filebeat the agent would always be Filebeat also if two Filebeat instances are run on the same machine. | keyword |
| agent.version | Version of the agent. | keyword |
| data_stream.dataset | Data stream dataset name. | constant_keyword |
| data_stream.namespace | Data stream namespace. | constant_keyword |
| data_stream.type | Data stream type. | constant_keyword |
| destination.address | Some event destination addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket.  You should always store the raw address in the `.address` field. Then it should be duplicated to `.ip` or `.domain`, depending on which one it is. | keyword |
| destination.as.number | Unique number allocated to the autonomous system. The autonomous system number (ASN) uniquely identifies each network on the Internet. | long |
| destination.as.organization.name | Organization name. | keyword |
| destination.bytes | Bytes sent from the destination to the source. | long |

| destination.geo.location | Longitude and latitude. | geo_point |
| destination.geo.name | User-defined description of a location, at the level of granularity they care about. Could be the name of their data centers, the floor number, if this describes a local physical entity, city names. Not typically used in automated geolocation. | keyword |
| destination.geo.postal_code | Postal code associated with the location. Values appropriate for this field may also be known as a postcode or ZIP code and will vary widely from country to country. | keyword |
| destination.geo.region_iso_code | Region ISO code. | keyword |

| destination.packets | Packets sent from the destination to the source. | long |
| destination.port | Port of the destination. | long |
| destination.registered_domain | The highest registered destination domain, stripped of the subdomain. For example, the registered domain for "foo.example.com" is "example.com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk". | keyword |
| destination.top_level_domain | The effective top level domain (eTLD), also known as the domain suffix, is the last part of the domain name. For example, the top level domain for example.com is "com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk". | keyword |
| dns.Ext | Object for all custom defined fields to live in. | object |
| dns.Ext.options | DNS options field, uint64, representing as a keyword to avoid overflows in ES | keyword |
| dns.Ext.status | DNS status field, uint32 | long |

Back slashes and quotes should be escaped. Tabs, carriage returns, and line feeds should be converted to \t, \r, and \n respectively. | keyword |
| dns.question.registered_domain | The highest registered domain, stripped of the subdomain. For example, the registered domain for "foo.example.com" is "example.com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk". | keyword |
| dns.question.subdomain | The subdomain is all of the labels under the registered_domain. If the domain has multiple levels of subdomain, such as "sub2.sub1.example.com", the subdomain field should contain "sub2.sub1", with no trailing period. | keyword |
| dns.question.top_level_domain | The effective top level domain (eTLD), also known as the domain suffix, is the last part of the domain name. For example, the top level domain for example.com is "com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk". | keyword |
| dns.question.type | The type of record being queried. | keyword |
| dns.resolved_ip | Array containing all IPs seen in `answers.data`. The `answers` array can be difficult to use, because of the variety of data formats it can contain. Extracting all IP addresses seen in there to `dns.resolved_ip` makes it possible to index them as IP addresses, and makes them easier to visualize and query for. | ip |
| ecs.version | ECS version this event conforms to. `ecs.version` is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
| event.action | The action captured by the event. This describes the information in the event. It is more specific than `event.category`. Examples are `group-add`, `process-started`, `file-created`. The value is normally defined by the implementer. | keyword |
| event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
| event.code | Identification code for this event, if one exists. Some event sources use event codes to identify messages unambiguously, regardless of message language or wording adjustments over time. An example of this is the Windows Event ID. | keyword |
| event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
| event.dataset | Name of the dataset. If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from. It's recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name. | keyword |
| event.hash | Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity. | keyword |
| event.id | Unique ID to describe the event. | keyword |
| event.ingested | Timestamp when an event arrived in the central data store. This is different from `@timestamp`, which is when the event originally occurred.  It's also different from `event.created`, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: `@timestamp` < `event.created` < `event.ingested`. | date |
| event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
| event.module | Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), `event.module` should contain the name of this module. | keyword |
| event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense. | keyword |
| event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
| event.sequence | Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regardless of the timestamp precision. | long |
| event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`. | long |
| event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |
| group.Ext | Object for all custom defined fields to live in. | object |

| host.architecture | Operating system architecture. | keyword |
| host.domain | Name of the domain of which the host is a member. For example, on Windows this could be the host's Active Directory domain or NetBIOS domain name. For Linux this could be the domain of the host's LDAP provider. | keyword |
| host.hostname | Hostname of the host. It normally contains what the `hostname` command returns on the host machine. | keyword |
| host.id | Unique host id. As hostname is not always unique, use values that are meaningful in your environment. Example: The current usage of `beat.name`. | keyword |
| host.ip | Host ip addresses. | ip |
| host.mac | Host MAC addresses. The notation format from RFC 7042 is suggested: Each octet (that is, 8-bit byte) is represented by two [uppercase] hexadecimal digits giving the value of the octet as an unsigned integer. Successive octets are separated by a hyphen. | keyword |
| host.name | Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name (FQDN), or a name specified by the user. The recommended value is the lowercase FQDN of the host. | keyword |
| host.os.Ext | Object for all custom defined fields to live in. | object |
| host.os.Ext.variant | A string value or phrase that further aid to classify or qualify the operating system (OS).  For example the distribution for a Linux OS will be entered in this field. | keyword |

If the OS you're dealing with is not listed as an expected value, the field should not be populated. Please let us know by opening an issue with ECS, to propose its addition. | keyword |
| host.os.version | Operating system version as a raw string. | keyword |
| host.type | Type of host. For Cloud providers this can be the machine type like `t2.medium`. If vm, this could be the container, for example, or other information meaningful in your environment. | keyword |
| host.uptime | Seconds the host has been up. | long |
| http.request.body.bytes | Size in bytes of the request body. | long |
| http.request.body.content | The full HTTP request body. | wildcard |

| message | For log events the message field contains the log message, optimized for viewing in a log viewer. For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event. If multiple messages exist, they can be combined into one message. | match_only_text |
| network.bytes | Total bytes transferred in both directions. If `source.bytes` and `destination.bytes` are known, `network.bytes` is their sum. | long |
| network.community_id | A hash of source and destination IPs and ports, as well as the protocol used in a communication. This is a tool-agnostic standard to identify flows. Learn more at https://github.com/corelight/community-id-spec. | keyword |
| network.direction | Direction of the network traffic. When mapping events from a host-based monitoring context, populate this field from the host's point of view, using the values "ingress" or "egress". When mapping events from a network or perimeter-based monitoring context, populate this field from the point of view of the network perimeter, using the values "inbound", "outbound", "internal" or "external". Note that "internal" is not crossing perimeter boundaries, and is meant to describe communication between two hosts within the perimeter. Note also that "external" is meant to describe traffic between two hosts that are external to the perimeter. This could for example be useful for ISPs or VPN service providers. | keyword |
| network.iana_number | IANA Protocol Number (https://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml). Standardized list of protocols. This aligns well with NetFlow and sFlow related logs which use the IANA Protocol Number. | keyword |

### process

#### Exported fields

| Field | Description | Type |
|---|---|---|
| @timestamp | Date/time when the event originated. This is the date/time extracted from the event, typically representing when the event was generated by the source. If the event source has no original timestamp, this value is typically populated by the first time the event was received by the pipeline. Required field for all events. | date |
| agent.ephemeral_id | Ephemeral identifier of this agent (if one exists). This id normally changes across restarts, but `agent.id` does not. | keyword |
| agent.id | Unique identifier of this agent (if one exists). Example: For Beats this would be beat.id. | keyword |
| agent.name | Custom name of the agent. This is a name that can be given to an agent. This can be helpful if for example two Filebeat instances are running on the same host but a human readable separation is needed on which Filebeat instance data is coming from. | keyword |
| agent.type | Type of the agent. The agent type always stays the same and should be given by the agent used. In case of Filebeat the agent would always be Filebeat also if two Filebeat instances are run on the same machine. | keyword |
| agent.version | Version of the agent. | keyword |
| cloud.account.id | The cloud account or organization id used to identify different entities in a multi-tenant environment. Examples: AWS account id, Google Cloud ORG Id, or other unique identifier. | keyword |
| cloud.instance.name | Instance name of the host machine. | keyword |
| cloud.project.id | The cloud project identifier. Examples: Google Cloud Project id, Azure Project id. | keyword |
| cloud.provider | Name of the cloud provider. Example values are aws, azure, gcp, or digitalocean. | keyword |
| cloud.region | Region in which this host, resource, or service is located. | keyword |
| container.id | Unique container id. | keyword |
| container.image.hash.all | An array of digests of the image the container was built on. Each digest consists of the hash algorithm and value in this format: `algorithm:value`. Algorithm names should align with the field names in the ECS hash field set. | keyword |
| container.image.name | Name of the image the container was built on. | keyword |
| container.image.tag | Container image tags. | keyword |
| container.name | Container name. | keyword |
| data_stream.dataset | Data stream dataset name. | constant_keyword |

| destination.geo.city_name | City name. | keyword |
| destination.geo.continent_code | Two-letter code representing continent's name. | keyword |
| destination.geo.continent_name | Name of the continent. | keyword |
| destination.geo.country_iso_code | Country ISO code. | keyword |
| destination.geo.country_name | Country name. | keyword |

| destination.geo.postal_code | Postal code associated with the location. Values appropriate for this field may also be known as a postcode or ZIP code and will vary widely from country to country. | keyword |
| destination.geo.region_iso_code | Region ISO code. | keyword |
| destination.geo.region_name | Region name. | keyword |
| destination.geo.timezone | The time zone of the location, such as IANA time zone name. | keyword |
| ecs.version | ECS version this event conforms to. `ecs.version` is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
| event.action | The action captured by the event. This describes the information in the event. It is more specific than `event.category`. Examples are `group-add`, `process-started`, `file-created`. The value is normally defined by the implementer. | keyword |
| event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
| event.code | Identification code for this event, if one exists. Some event sources use event codes to identify messages unambiguously, regardless of message language or wording adjustments over time. An example of this is the Windows Event ID. | keyword |
| event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
| event.dataset | Name of the dataset. If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from. It's recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name. | keyword |
| event.hash | Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity. | keyword |
| event.id | Unique ID to describe the event. | keyword |
| event.ingested | Timestamp when an event arrived in the central data store. This is different from `@timestamp`, which is when the event originally occurred.  It's also different from `event.created`, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: `@timestamp` < `event.created` < `event.ingested`. | date |
| event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
| event.module | Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), `event.module` should contain the name of this module. | keyword |
| event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense. | keyword |
| event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
| event.sequence | Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regardless of the timestamp precision. | long |
| event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`. | long |
| event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |

| host.boot.id | Linux boot uuid taken from /proc/sys/kernel/random/boot_id. Note the boot_id value from /proc may or may not be the same in containers as on the host. Some container runtimes will bind mount a new boot_id value onto the proc file in each container. | keyword |
| host.domain | Name of the domain of which the host is a member. For example, on Windows this could be the host's Active Directory domain or NetBIOS domain name. For Linux this could be the domain of the host's LDAP provider. | keyword |

| host.os.version | Operating system version as a raw string. | keyword |
| host.pid_ns_ino | This is the inode number of the namespace in the namespace file system (nsfs). Unsigned int inum in include/linux/ns_common.h. | keyword |
| host.type | Type of host. For Cloud providers this can be the machine type like `t2.medium`. If vm, this could be the container, for example, or other information meaningful in your environment. | keyword |
| host.uptime | Seconds the host has been up. | long |
| message | For log events the message field contains the log message, optimized for viewing in a log viewer. For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event. If multiple messages exist, they can be combined into one message. | match_only_text |

| process.entry_leader.name | Process name. Sometimes called program name or similar. | keyword |
| process.entry_leader.parent.entity_id | Unique identifier for the process. The implementation of this is specified by the data source, but some examples of what could be used here are a process-generated UUID, Sysmon Process GUIDs, or a hash of some uniquely identifying components of a process.

| process.entry_leader.real_user.name | Short name or login of the user. | keyword |
| process.entry_leader.same_as_process | This boolean is used to identify if a leader process is the same as the top level process. For example, if `process.group_leader.same_as_process = true`, it means the process event in question is the leader of its process group. Details under `process.*` like `pid` would be the same under `process.group_leader.*` The same applies for both `process.session_leader` and `process.entry_leader`. This field exists to the benefit of EQL and other rule engines since it's not possible to compare equality between two fields in a single document. e.g `process.entity_id` = `process.group_leader.entity_id` (top level process is the process group leader) OR `process.entity_id` = `process.entry_leader.entity_id` (top level process is the entry session leader) Instead these rules could be written like: `process.group_leader.same_as_process: true` OR `process.entry_leader.same_as_process: true` Note: This field is only set on `process.entry_leader`, `process.session_leader` and `process.group_leader`. | boolean |

| ecs.version | ECS version this event conforms to. `ecs.version` is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
| event.action | The action captured by the event. This describes the information in the event. It is more specific than `event.category`. Examples are `group-add`, `process-started`, `file-created`. The value is normally defined by the implementer. | keyword |
| event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
| event.code | Identification code for this event, if one exists. Some event sources use event codes to identify messages unambiguously, regardless of message language or wording adjustments over time. An example of this is the Windows Event ID. | keyword |
| event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
| event.dataset | Name of the dataset. If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from. It's recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name. | keyword |
| event.hash | Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity. | keyword |
| event.id | Unique ID to describe the event. | keyword |
| event.ingested | Timestamp when an event arrived in the central data store. This is different from `@timestamp`, which is when the event originally occurred.  It's also different from `event.created`, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: `@timestamp` < `event.created` < `event.ingested`. | date |
| event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
| event.module | Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), `event.module` should contain the name of this module. | keyword |
| event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense. | keyword |
| event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
| event.sequence | Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regardless of the timestamp precision. | long |
| event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`. | long |
| event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |

| host.os.platform | Operating system platform (such centos, ubuntu, windows). | keyword |
| host.os.type | Use the `os.type` field to categorize the operating system into one of the broad commercial families. If the OS you're dealing with is not listed as an expected value, the field should not be populated. Please let us know by opening an issue with ECS, to propose its addition. | keyword |
| host.os.version | Operating system version as a raw string. | keyword |
| host.type | Type of host. For Cloud providers this can be the machine type like `t2.medium`. If vm, this could be the container, for example, or other information meaningful in your environment. | keyword |
| host.uptime | Seconds the host has been up. | long |
| message | For log events the message field contains the log message, optimized for viewing in a log viewer. For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event. If multiple messages exist, they can be combined into one message. | match_only_text |
| process.Ext | Object for all custom defined fields to live in. | object |
| process.Ext.ancestry | An array of entity_ids indicating the ancestors for this event | keyword |

## Metrics

The metrics type of documents are stored in `metrics-endpoint.*` indices. The following sections define the mapped fields
sent by the endpoint.

### metadata

#### Exported fields

| Field | Description | Type |
|---|---|---|
| @timestamp | Date/time when the event originated. This is the date/time extracted from the event, typically representing when the event was generated by the source. If the event source has no original timestamp, this value is typically populated by the first time the event was received by the pipeline. Required field for all events. | date |
| Endpoint.capabilities | Enabled capabilities | keyword |
| Endpoint.configuration | Configuration fields represent the intended and applied setting for fields not part of a Policy setting This reflects what a given field is configured to do. The actual state of that same field is found in Endpoint.state | object |
| Endpoint.configuration.isolation | Configuration setting for Host Isolation from the network | boolean |
| Endpoint.policy | The policy fields are used to hold information about applied policy. | object |
| Endpoint.policy.applied | information about the policy that is applied | object |
| Endpoint.policy.applied.id | the id of the applied policy | keyword |
| Endpoint.policy.applied.name | the name of this applied policy | keyword |
| Endpoint.policy.applied.status | the status of the applied policy | keyword |
| Endpoint.state | Represents the current state of a non-policy setting These fields reflect the current status of a field, which may differ from what it is configured to be (see Endpoint.configuration) | object |
| Endpoint.state.isolation | Current network isolation state of the host | boolean |
| Endpoint.status | The current status of the endpoint e.g. enrolled, unenrolled. | keyword |
| agent.id | Unique identifier of this agent (if one exists). Example: For Beats this would be beat.id. | keyword |
| agent.name | Custom name of the agent. This is a name that can be given to an agent. This can be helpful if for example two Filebeat instances are running on the same host but a human readable separation is needed on which Filebeat instance data is coming from. | keyword |
| agent.type | Type of the agent. The agent type always stays the same and should be given by the agent used. In case of Filebeat the agent would always be Filebeat also if two Filebeat instances are run on the same machine. | keyword |
| agent.version | Version of the agent. | keyword |
| data_stream.dataset | Data stream dataset name. | constant_keyword |
| data_stream.namespace | Data stream namespace. | constant_keyword |
| data_stream.type | Data stream type. | constant_keyword |
| ecs.version | ECS version this event conforms to. `ecs.version` is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
| elastic.agent | The agent fields contain data about the Elastic Agent. The Elastic Agent is the management agent that manages other agents or process on the host. | object |
| elastic.agent.id | Unique identifier of this elastic agent (if one exists). | keyword |
| event.action | The action captured by the event. This describes the information in the event. It is more specific than `event.category`. Examples are `group-add`, `process-started`, `file-created`. The value is normally defined by the implementer. | keyword |
| event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
| event.code | Identification code for this event, if one exists. Some event sources use event codes to identify messages unambiguously, regardless of message language or wording adjustments over time. An example of this is the Windows Event ID. | keyword |
| event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
| event.dataset | Name of the dataset. If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from. It's recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name. | keyword |
| event.hash | Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity. | keyword |
| event.id | Unique ID to describe the event. | keyword |
| event.ingested | Timestamp when an event arrived in the central data store. This is different from `@timestamp`, which is when the event originally occurred.  It's also different from `event.created`, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: `@timestamp` < `event.created` < `event.ingested`. | date |
| event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
| event.module | Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), `event.module` should contain the name of this module. | keyword |
| event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense. | keyword |
| event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
| event.sequence | Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regardless of the timestamp precision. | long |
| event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`. | long |
| event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |
| host.architecture | Operating system architecture. | keyword |
| host.domain | Name of the domain of which the host is a member. For example, on Windows this could be the host's Active Directory domain or NetBIOS domain name. For Linux this could be the domain of the host's LDAP provider. | keyword |
| host.hostname | Hostname of the host. It normally contains what the `hostname` command returns on the host machine. | keyword |
| host.id | Unique host id. As hostname is not always unique, use values that are meaningful in your environment. Example: The current usage of `beat.name`. | keyword |
| host.ip | Host ip addresses. | ip |
| host.mac | Host MAC addresses. The notation format from RFC 7042 is suggested: Each octet (that is, 8-bit byte) is represented by two [uppercase] hexadecimal digits giving the value of the octet as an unsigned integer. Successive octets are separated by a hyphen. | keyword |
| host.name | Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name (FQDN), or a name specified by the user. The recommended value is the lowercase FQDN of the host. | keyword |
| host.os.Ext | Object for all custom defined fields to live in. | object |
| host.os.Ext.variant | A string value or phrase that further aid to classify or qualify the operating system (OS).  For example the distribution for a Linux OS will be entered in this field. | keyword |
| host.os.family | OS family (such as redhat, debian, freebsd, windows). | keyword |
| host.os.full | Operating system name, including the version or code name. | keyword |
| host.os.kernel | Operating system kernel version as a raw string. | keyword |
| host.os.name | Operating system name, without the version. | keyword |
| host.os.platform | Operating system platform (such centos, ubuntu, windows). | keyword |
| host.os.type | Use the `os.type` field to categorize the operating system into one of the broad commercial families. If the OS you're dealing with is not listed as an expected value, the field should not be populated. Please let us know by opening an issue with ECS, to propose its addition. | keyword |
| host.os.version | Operating system version as a raw string. | keyword |
| host.type | Type of host. For Cloud providers this can be the machine type like `t2.medium`. If vm, this could be the container, for example, or other information meaningful in your environment. | keyword |
| host.uptime | Seconds the host has been up. | long |

It's recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name. | keyword |
| event.hash | Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity. | keyword |
| event.id | Unique ID to describe the event. | keyword |
| event.ingested | Timestamp when an event arrived in the central data store. This is different from `@timestamp`, which is when the event originally occurred.  It's also different from `event.created`, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: `@timestamp` < `event.created` < `event.ingested`. | date |
| event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
| event.module | Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), `event.module` should contain the name of this module. | keyword |
| event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense. | keyword |
| event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
| event.sequence | Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regardless of the timestamp precision. | long |
| event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`. | long |
| event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |
| host.architecture | Operating system architecture. | keyword |
| host.hostname | Hostname of the host. It normally contains what the `hostname` command returns on the host machine. | keyword |
| host.id | Unique host id. As hostname is not always unique, use values that are meaningful in your environment. Example: The current usage of `beat.name`. | keyword |
| host.ip | Host ip addresses. | ip |
| host.mac | Host MAC addresses. The notation format from RFC 7042 is suggested: Each octet (that is, 8-bit byte) is represented by two [uppercase] hexadecimal digits giving the value of the octet as an unsigned integer. Successive octets are separated by a hyphen. | keyword |
| host.name | Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name (FQDN), or a name specified by the user. The recommended value is the lowercase FQDN of the host. | keyword |
| host.os.Ext | Object for all custom defined fields to live in. | object |
| host.os.Ext.variant | A string value or phrase that further aid to classify or qualify the operating system (OS).  For example the distribution for a Linux OS will be entered in this field. | keyword |
| host.os.family | OS family (such as redhat, debian, freebsd, windows). | keyword |
| host.os.full | Operating system name, including the version or code name. | keyword |
| host.os.kernel | Operating system kernel version as a raw string. | keyword |
| host.os.name | Operating system name, without the version. | keyword |
| host.os.platform | Operating system platform (such centos, ubuntu, windows). | keyword |
| host.os.type | Use the `os.type` field to categorize the operating system into one of the broad commercial families. If the OS you're dealing with is not listed as an expected value, the field should not be populated. Please let us know by opening an issue with ECS, to propose its addition. | keyword |
| host.os.version | Operating system version as a raw string. | keyword |
| message | For log events the message field contains the log message, optimized for viewing in a log viewer. For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event. If multiple messages exist, they can be combined into one message. | match_only_text |
