    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.

    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)

    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)

    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)

    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.

    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)

    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.

  • references array[string] Required

    Array containing notes about or references to relevant information about the rule. Defaults to an empty array.

  • related_integrations array[object] Required

    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.
