Detection rule mapping enables your organization to see which detection rules are available to identify specific techniques.
The primary purpose of the mapping is to provide visibility if your organization has the necessary detection rules to identify when an alert or event is triggered as a result of an attack by an adversary using a specific technique.
For example, view the following illustration that shows a list of the detection rules mapped to various techniques. You can also view this information in the MITRE-ATT&CK navigator.
If you do not intend to use the base system SIEM auto-extraction rules, then enable the automatic rollup of MITRE-ATT&CK TTPs based on the detection rule mapping. You can populate the alert or event rule that triggers the security incident in the Alert Rule name field. You can also populate the Alert Rule name field by using SIEM integration, email parsing, manual creation, etc. For more information, see Rollup MITRE-ATT&CK information from detection rules.
The detection rules feature has been updated to include mapping a single tactic to multiple techniques. Previously, you could map a single tactic with a single technique. If you are upgrading the Threat Intelligence plugin from version 12.0.4 to a higher version, then review the following points before using the detection rules in MITRE-ATT&CK module.
- You find multiple records merged into a single record if the fields - rule name, alert sensor, source, category, subcategory, and MITRE-ATT&CK tactic are common.
- The old records are marked as true in the deprecated column and false in the active column.
- The new merged records are available for use and are marked as false in the deprecated column and true in the active column.
- After you verify the upgrade, and view that all your detection rules are successfully migrated, you can delete the old records that are marked as true in the deprecated column.
