The IR lifecycle includes preparation, detection and analysis, containment, eradication, recovery, and post-incident review. Each phase ensures threats are handled systematically to minimize damage and prevent recurrence. A Computer Security Incident Response Team (CSIRT) is a specialized group responsible for detecting, investigating, containing, and recovering from cybersecurity incidents within an organization. Digital forensics involves collecting, preserving, and analyzing digital evidence from systems, networks, and devices. It follows strict chain of custody procedures to ensure evidence integrity for investigations or legal proceedings. Forensic acquisition is the process of creating verified copies of digital data from devices or systems while preserving the original evidence. It ensures investigators work with accurate data without altering the source. Frameworks like GDPR, HIPAA, PCI DSS, SOX, and the NIST Cybersecurity Framework define incident notification requirements, data handling obligations, and response timelines that organizations must follow after a breach.
