Related integration is a potential dependency of a rule. It's assumed that if the user installs one of the related integrations of a rule, the rule might start to work properly because it will have source events (generated by this integration) potentially matching the rule's query.

NOTE: Proper work is not guaranteed, because a related integration, if installed, can be configured differently or generate data that is not necessarily relevant for this rule.

Related integration is a combination of a Fleet package and (optionally) one of the package's "integrations" that this package contains. It is represented by 3 properties:
- package: name of the package (required, unique id)
- version: version of the package (required, semver-compatible)
- integration: name of the integration of this package (optional, id within the package)
There are Fleet packages like windows that contain only one integration; in this case, integration should be unspecified. There are also packages like aws and azure that contain several integrations; in this case, integration should be specified.

@example const x: RelatedIntegration = { package: 'windows', version: '1.5.x', };

@example const x: RelatedIntegration = { package: 'azure', version: '~1.1.6', integration: 'activitylogs', };

Related integration is a potential dependency of a rule. It's assumed that if the user installs one of the related integrations of a rule, the rule might start to work properly because it will have source events (generated by this integration) potentially matching the rule's query.

NOTE: Proper work is not guaranteed, because a related integration, if installed, can be configured differently or generate data that is not necessarily relevant for this rule.

Related integration is a combination of a Fleet package and (optionally) one of the package's "integrations" that this package contains. It is represented by 3 properties:
- package: name of the package (required, unique id)
- version: version of the package (required, semver-compatible)
- integration: name of the integration of this package (optional, id within the package)
There are Fleet packages like windows that contain only one integration; in this case, integration should be unspecified. There are also packages like aws and azure that contain several integrations; in this case, integration should be specified.

@example const x: RelatedIntegration = { package: 'windows', version: '1.5.x', };

@example const x: RelatedIntegration = { package: 'azure', version: '~1.1.6', integration: 'activitylogs', };

related_integrations array[object] Required

Hide related_integrations attributes Show related_integrations attributes object

Related integration is a potential dependency of a rule. It's assumed that if the user installs one of the related integrations of a rule, the rule might start to work properly because it will have source events (generated by this integration) potentially matching the rule's query.

NOTE: Proper work is not guaranteed, because a related integration, if installed, can be configured differently or generate data that is not necessarily relevant for this rule.

Related integration is a combination of a Fleet package and (optionally) one of the package's "integrations" that this package contains. It is represented by 3 properties:

package: name of the package (required, unique id)

version: version of the package (required, semver-compatible)

integration: name of the integration of this package (optional, id within the package)

There are Fleet packages like windows that contain only one integration; in this case, integration should be unspecified. There are also packages like aws and azure that contain several integrations; in this case, integration should be specified.

@example const x: RelatedIntegration = { package: 'windows', version: '1.5.x', };

@example const x: RelatedIntegration = { package: 'azure', version: '~1.1.6', integration: 'activitylogs', };

Required field is an event field that must be present in the source indices of a given rule.

@example const standardEcsField: RequiredField = { name: 'event.action', type: 'keyword', ecs: true, };

Added in PR #163235 Right now we only have a single field but anticipate adding more related fields to store various configuration states such as override - where a user might say if they want only these fields to display, or if they want these fields + the fields we select. When expanding this field, it may look something like:

const investigationFields = z.object({ field_names: NonEmptyArray(NonEmptyString), override: z.boolean().optional(), });

Related integration is a potential dependency of a rule. It's assumed that if the user installs one of the related integrations of a rule, the rule might start to work properly because it will have source events (generated by this integration) potentially matching the rule's query.

NOTE: Proper work is not guaranteed, because a related integration, if installed, can be configured differently or generate data that is not necessarily relevant for this rule.

Related integration is a combination of a Fleet package and (optionally) one of the package's "integrations" that this package contains. It is represented by 3 properties:

package: name of the package (required, unique id)

version: version of the package (required, semver-compatible)

integration: name of the integration of this package (optional, id within the package)

There are Fleet packages like windows that contain only one integration; in this case, integration should be unspecified. There are also packages like aws and azure that contain several integrations; in this case, integration should be specified.

@example const x: RelatedIntegration = { package: 'windows', version: '1.5.x', };

Related integration is a potential dependency of a rule. It's assumed that if the user installs one of the related integrations of a rule, the rule might start to work properly because it will have source events (generated by this integration) potentially matching the rule's query.

NOTE: Proper work is not guaranteed, because a related integration, if installed, can be configured differently or generate data that is not necessarily relevant for this rule.

Related integration is a combination of a Fleet package and (optionally) one of the package's "integrations" that this package contains. It is represented by 3 properties:

package: name of the package (required, unique id)

version: version of the package (required, semver-compatible)

integration: name of the integration of this package (optional, id within the package)

There are Fleet packages like windows that contain only one integration; in this case, integration should be unspecified. There are also packages like aws and azure that contain several integrations; in this case, integration should be specified.

investigation_fields object

Schema for fields relating to investigation fields. These are user defined fields we use to highlight in various features in the UI such as alert details flyout and exceptions auto-population from alert. Added in PR #163235 Right now we only have a single field but anticipate adding more related fields to store various configuration states such as override - where a user might say if they want only these fields to display, or if they want these fields + the fields we select. When expanding this field, it may look something like:

const investigationFields = z.object({ field_names: NonEmptyArray(NonEmptyString), override: z.boolean().optional(), });

related_integrations array[object] Required

Hide related_integrations attributes Show related_integrations attributes object

Related integration is a potential dependency of a rule. It's assumed that if the user installs one of the related integrations of a rule, the rule might start to work properly because it will have source events (generated by this integration) potentially matching the rule's query.

NOTE: Proper work is not guaranteed, because a related integration, if installed, can be configured differently or generate data that is not necessarily relevant for this rule.

Related integration is a combination of a Fleet package and (optionally) one of the package's "integrations" that this package contains. It is represented by 3 properties:

package: name of the package (required, unique id)

version: version of the package (required, semver-compatible)

integration: name of the integration of this package (optional, id within the package)

There are Fleet packages like windows that contain only one integration; in this case, integration should be unspecified. There are also packages like aws and azure that contain several integrations; in this case, integration should be specified.

@example const x: RelatedIntegration = { package: 'windows', version: '1.5.x', };

@example const x: RelatedIntegration = { package: 'azure', version: '~1.1.6', integration: 'activitylogs', };

required_fields array[object] Required

Hide required_fields attributes Show required_fields attributes object

Describes an Elasticsearch field that is needed for the rule to function.

Almost all types of Security rules check source event documents for a match to some kind of query or filter. If a document has certain field with certain values, then it's a match and the rule will generate an alert.

Required field is an event field that must be present in the source indices of a given rule.

@example const standardEcsField: RequiredField = { name: 'event.action', type: 'keyword', ecs: true, };

@example const nonEcsField: RequiredField = { name: 'winlog.event_data.AttributeLDAPDisplayName', type: 'keyword', ecs: false, };
