Manage indicator relationships - Administrator Guide - Threat Intel Management Guide - Cortex XSIAM - Cortex - Security Operations

Indicator relationships are connections between different indicators. These relationships can be IP addresses related to one another, domains impersonating legitimate domains, etc. These relationships enable you to enhance investigations with information about indicators and how they might be connected to other incidents or indicators. For example, if you have a phishing incident with several indicators, one of those indicators might lead to another indicator, which is a malicious threat actor. Once you know the threat actor, you can investigate to see the incidents it was involved in, its known TTPs (tactics, techniques, and procedures), and other indicators that might be related to the threat actor. The initial incident which started as a phishing investigation immediately becomes a true positive and relates to a specific malicious entity.

Relationships are created from threat intel feeds and enrichment integrations that support the automatic creation of relationships, such as AlienVault OTX v2 and URLhaus, by selecting Create relationships in the integration settings. Based on the information that exists in the integrations, the relationships are formed.

You can view indicator relationships by clicking on the indicator from an alert, and then from the Quick View window click the Relationships tab.

The Threat Intel Management system in Cortex XSIAM includes a feed that brings in a collection of threat intel objects as indicators. These indicators are stored in the Cortex XSIAM threat intel library and include Malware, Attack Patterns, Campaigns, and Threat Actors. When you add or update an indicator from Unit 42 Intel, a relationship is formed in the database between the relevant threat intel object and the new, or updated, indicator.
