CISA releases logging guidance for federal agencies and critical infrastructure

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has released the Logging Reference Architecture (LRA) to improve network monitoring and visibility. While developed to help federal civilian agencies meet the requirements of OMB Memorandum M-26-14, CISA is encouraging critical infrastructure operators, state, local, territorial, and tribal governments to adopt the framework as a benchmark.

The LRA focuses on two primary operational goals: Continuous Event Monitoring (CEM) for near-real-time detection and response, and Threat Hunting, Investigation, Response, and Forensics (THIRF) to reconstruct events following a compromise. The guidance emphasizes that simply collecting logs is insufficient; data must be timely, detailed, and reliable to be useful during an actual incident.

The framework includes assessment tools and checklists to evaluate architectural decisions and practical implementation. It also provides guidance on integrating artificial intelligence into logging processes to counter threats accelerated by automation.
