Security Incident Response (SIRT)
Security Incident Response (SIRT) is the structured practice of detecting, containing, analyzing, and recovering from cybersecurity breaches and attacks. A Security Incident Response Team (SIRT) coordinates cross-functional efforts across IT, legal, communications, and leadership to minimize damage and restore operations. It encompasses the full lifecycle defined by NIST SP 800-61: preparation, detection and analysis, containment/eradication/recovery, and post-incident review.
As AI companies store sensitive model weights, training data, and user PII at scale, a single breach can halt operations, trigger regulatory penalties, and destroy user trust. Regulators and customers now expect documented incident response plans, especially under frameworks like NIST CSF 2.0 (updated 2024) and the EU AI Act. SIRT roles are consistently among the highest-demand positions in security operations, with companies competing for professionals who can lead response under pressure.
