Advanced settings

Update advanced Elastic Security settings.

The advanced settings determine:

  • Which indices Elastic Security uses to retrieve data
  • Machine learning anomaly score display threshold
  • The navigation menu style used throughout the Elastic Security app
  • Whether the news feed is displayed on the Overview dashboard
  • The default time interval used to filter Elastic Security pages
  • The default Elastic Security pages refresh time
  • Which IP reputation links appear on IP detail pages
  • Whether cross-cluster search (CCS) privilege warnings are displayed
  • Whether related integrations are displayed on the Rules page tables
  • The options provided in the alert tag menu

You must have the appropriate user role to access and change advanced settings.

Warning

Modifying advanced settings can affect performance and cause problems that are difficult to diagnose. Setting a property value to a blank field reverts to the default behavior, which might not be compatible with other configuration settings. Deleting a custom setting removes it permanently.

Access advanced settings

To access advanced settings, go to Project SettingsManagementAdvanced Settings, then scroll down to Security Solution settings.

Tip

For more information on non-Security settings, refer to Advanced Settings. Some settings might not be available in serverless projects.

Update default Elastic Security indices

The securitySolution:defaultIndex field defines which Elasticsearch indices the Elastic Security app uses to collect data. By default, index patterns are used to match sets of Elasticsearch indices:

  • apm-*-transaction*
  • auditbeat-*
  • endgame-*
  • filebeat-*
  • logs-*
  • packetbeat-*
  • winlogbeat-*

Note

Index patterns use wildcards to specify a set of indices. For example, the filebeat-* index pattern means all indices starting with filebeat- are available in the Elastic Security app.

All of the default index patterns match Beats and Elastic Agent indices. This means all data shipped via Beats and the Elastic Agent is automatically added to the Elastic Security app.

You can add or remove any indices and index patterns as required, with a maximum of 50 items in the comma-delimited list. For background information on Elasticsearch indices, refer to Data in: documents and indices.

Note

If you leave the -*elastic-cloud-logs-* index pattern selected, all Elastic cloud logs are excluded from all queries in the Elastic Security app by default. This is to avoid adding data from cloud monitoring to the app.

Important

Elastic Security requires ECS-compliant data. If you use third-party data collectors to ship data to Elasticsearch, the data must be mapped to ECS. Elastic Security ECS field reference lists ECS fields used in Elastic Security.

Update default Elastic Security threat intelligence indices

The securitySolution:defaultThreatIndex advanced setting specifies threat intelligence indices that Elastic Security features query for ingested threat indicators. This setting affects features that query threat intelligence indices, such as the Threat Intelligence view on the Overview page, indicator match rules, and the alert enrichment query.

You can specify a maximum of 10 threat intelligence indices; multiple indices must be separated by commas. By default, only the logs-ti* index pattern is specified. Do not remove or overwrite this index pattern, as it is used by Elastic Agent integrations.

Important

Threat intelligence indices aren't required to be ECS-compatible for use in indicator match rules. However, we strongly recommend compatibility if you want your alerts to be enriched with relevant threat indicator information. When searching for threat indicator data, indicator match rules use the threat indicator path specified in the Indicator prefix override advanced setting. Visit Configure advanced rule settings for more information.

Telemetry settings

Elastic transmits certain information about Elastic Security when users interact with the Elastic Security app, detailed below. Elastic redacts or obfuscates personal data (IP addresses, host names, usernames, etc.) before transmitting messages. Security-specific telemetry events include:

  • Detection rule security alerts: Information about Elastic-authored prebuilt detection rules using the detection engine. Examples of alert data include machine learning job influencers, process names, and cloud audit events.
  • Elastic Endpoint Security alerts: Information about malicious activity detected using Elastic Endpoint detection engines. Examples of alert data include malicious process names, digital signatures, and file names written by the malicious software. Examples of alert metadata include the time of the alert, the Elastic Endpoint version and related detection engine versions.
  • Configuration data for Elastic Endpoint: Information about the configuration of Elastic Endpoint deployments. Examples of configuration data include the Endpoint versions, operating system versions, and performance counters for Endpoint.
  • Exception list entries for Elastic rules: Information about exceptions added for Elastic rules. Examples include trusted applications, detection exceptions, and rule exceptions.
  • Security alert activity records: Information about actions taken on alerts generated in the Elastic Security app, such as acknowledged or closed.

To learn more, refer to our Privacy Statement.

Set machine learning score threshold

When security machine learning jobs are enabled, this setting determines the threshold above which anomaly scores appear in Elastic Security:

  • securitySolution:defaultAnomalyScore

Modify news feed settings

You can change these settings, which affect the news feed displayed on the Elastic Security Overview page:

  • securitySolution:enableNewsFeed: Enables the security news feed on the Security Overview page.

  • securitySolution:newsFeedUrl: The URL from which the security news feed content is retrieved.

Display the expandable flyout

The securitySolution:enableExpandableFlyout setting enables the expandable alert details flyout on the Alerts page. This setting is turned on by default. Turn it off to apply a simplified alert details flyout design.

Exclude cold and frozen tier data from analyzer queries

Including data from cold and frozen data tiers in visual event analyzer queries may result in performance degradation. The securitySolution:excludeColdAndFrozenTiersInAnalyzer setting allows you to exclude this data from analyzer queries. This setting is turned off by default.

Change the default search interval and data refresh time

These settings determine the default time interval and refresh rate Elastic Security pages use to display data when you open the app:

  • securitySolution:timeDefaults: Default time interval
  • securitySolution:refreshIntervalDefaults: Default refresh rate

Note

Refer to Date Math for information about the syntax. The UI time filter overrides the default values.

On IP details pages (NetworkIP address), links to external sites for verifying the IP address's reputation are displayed. By default, links to these sites are listed: TALOS and VIRUSTOTAL.

The securitySolution:ipReputationLinks field determines which IP reputation sites are listed. To modify the listed sites, edit the field's JSON array. These fields must be defined in each array element:

  • name: The link's UI display name.
  • url_template: The link's URL. It can include {{ip}}, which is placeholder for the IP address you are viewing on the IP detail page.

Example

Adds a link to https://www.dnschecker.org on IP detail pages:

[
  { "name": "virustotal.com", "url_template": "https://www.virustotal.com/gui/search/{{ip}}" },
  { "name": "dnschecker.org", "url_template": "https://www.dnschecker.org/ip-location.php?ip={{ip}}" },
  { "name": "talosIntelligence.com", "url_template": "https://talosintelligence.com/reputation_center/lookup?search={{ip}}" }
]

Configure cross-cluster search privilege warnings

Each time a detection rule runs using a remote cross-cluster search (CCS) index pattern, it will return a warning saying that the rule may not have the required read privileges to the remote index. Because privileges cannot be checked across remote indices, this warning displays even when the rule actually does have read privileges to the remote index.

If you've ensured that your detection rules have the required privileges across your remote indices, you can use the securitySolution:enableCcsWarning setting to disable this warning and reduce noise.

By default, Elastic prebuilt rules in the Rules and Rule Monitoring tables include a badge showing how many related integrations have been installed. Turn off securitySolution:showRelatedIntegrations to hide this in the rules tables (related integrations will still appear on rule details pages).

Manage alert tag options

The securitySolution:alertTags field determines which options display in the alert tag menu. The default alert tag options are Duplicate, False Positive, and Further investigation required. You can update the alert tag menu by editing these options or adding more. To learn more about using alert tags, refer to Apply and filter alert tags.
