Supplemental Guidance
To maximize the effectiveness of monitoring, it is important to know what threat observables and indicators the sensors need to be searching for. By using well-established frameworks, services, and automated tools, organizations improve their ability to rapidly share and feed the relevant threat detection signatures into monitoring tools.
Practitioner Notes
This enhancement requires using automated tools to share and consume threat intelligence rather than relying solely on manual processes like email alerts or PDF reports.
Example 1: Implement STIX/TAXII feeds in your SIEM so threat indicators (malicious IPs, domains, file hashes) are automatically ingested and correlated against your network traffic and endpoint telemetry without human intervention.
Example 2: In Microsoft Sentinel, go to Threat Intelligence → Data Connectors and enable the TAXII or Microsoft Defender Threat Intelligence connector. This automatically pulls in threat indicators and creates detection rules that fire when those indicators are seen in your environment.
