Security Analytics settings

The Security Analytics plugin supports the following settings. All settings in this list are dynamic:

plugins.security_analytics.index_timeout (Time value): The timeout for creating detectors, findings, rules, and custom log types using the REST APIs. Default is 60 seconds.

plugins.security_analytics.alert_history_enabled (Boolean): Specifies whether to create .opensearch-sap-<detector_type>-alerts-history-<date> indexes. Default is true.

plugins.security_analytics.alert_finding_enabled (Boolean): Specifies whether to create .opensearch-sap-<detector_type>-findings-<date> indexes. Default is true.

plugins.security_analytics.alert_history_rollover_period (Time value): Specifies how frequently to roll over and delete alert history indexes. Default is 12 hours.

plugins.security_analytics.alert_finding_rollover_period (Time value): Specifies how frequently to roll over and delete finding history indexes. Default is 12 hours.

plugins.security_analytics.correlation_history_rollover_period (Time value): Specifies how frequently to roll over and delete correlation history indexes. Default is 12 hours.

plugins.security_analytics.alert_history_max_age (Time value): The oldest document to store in the alert history index before creating a new index. If the number of alerts in this time period does not exceed alert_history_max_docs, a new alert history index is created per period (for example, one index every 30 days). Default is 30 days.

plugins.security_analytics.finding_history_max_age (Time value): The oldest document to store in the finding history index before creating a new index. If the number of findings in this time period does not exceed finding_history_max_docs, a new finding history index is created per period (for example, one index every 30 days). Default is 30 days.

plugins.security_analytics.correlation_history_max_age (Time value): The oldest document to store in the correlation history index before creating a new index. If the number of correlations in this time period does not exceed correlation_history_max_docs, a new correlation history index is created per period (for example, one index every 30 days). Default is 30 days.

plugins.security_analytics.alert_history_max_docs (Integer): The maximum number of alerts to store in the alert history index before creating a new index. Default is 1,000.

plugins.security_analytics.alert_finding_max_docs (Integer): The maximum number of findings to store in the findings history index before creating a new index. Default is 1,000.

plugins.security_analytics.correlation_history_max_docs (Integer): The maximum number of correlations to store in the correlation history index before creating a new index. Default is 1,000.

plugins.security_analytics.alert_history_retention_period (Time value): The amount of time to keep alert history indexes before automatically deleting them. Default is 60 days.

plugins.security_analytics.finding_history_retention_period (Time value): The amount of time to keep finding history indexes before automatically deleting them. Default is 60 days.

plugins.security_analytics.correlation_history_retention_period (Time value): The amount of time to keep correlation history indexes before automatically deleting them. Default is 60 days.

plugins.security_analytics.request_timeout (Time value): The timeout for all requests the Security Analytics plugin sends to other parts of OpenSearch. Default is 10 seconds.

plugins.security_analytics.action_throttle_max_value (Time value): The maximum amount of time you can set for action throttling. Default is 24 hours. (This value displays as 1440 minutes in OpenSearch Dashboards.)

plugins.security_analytics.filter_by_backend_roles (Boolean): When set to true, restricts access to detectors, alerts, findings, and custom log types by backend role when enabled. Default is false.

plugins.security_analytics.enable_workflow_usage (Boolean): Supports the Alerting plugin workflow integration with Security Analytics. Determines whether composite monitor workflows are generated for the Alerting plugin after creating a new threat detector in Security Analytics. When set to true, composite monitor workflows based on an associated threat detector's configuration are enabled. When set to false, composite monitor workflows based on an associated threat detector's configuration are disabled. Default is true. For more information about Alerting plugin workflow integration with Security Analytics, see Integrated Alerting plugin workflows.

plugins.security_analytics.correlation_time_window (Time value): Security Analytics generates correlations within a time window. This setting specifies the time window within which documents must be indexed into the index in order to be included in the same correlation. Default is 5 minutes.

plugins.security_analytics.mappings.default_schema (String): The default mapping schema used for configuring a field mapping for a security analytics detector. Default is ecs.

plugins.security_analytics.threatintel.tifjob.update_interval (Time value): The threat intelligence feature uses a job runner to periodically fetch new feeds. This setting is the rate at which the runner fetches and updates these new feeds. Default is 1440 minutes.

plugins.security_analytics.threatintel.tifjob.batch_size (Integer): The maximum number of documents to ingest in a bulk request during the threat intelligence feed data creation process. Default is 10,000.

plugins.security_analytics.threat_intel_timeout (Time value): The timeout value for creating and deleting threat intelligence feed data. Default is 30 seconds.
