Incident response uses digital forensics to determine what happened, how an attacker gained access, what systems or data were affected, and whether malicious activity remains. Forensic work can include evidence preservation, endpoint and network analysis, malware analysis, timeline development, and investigation of identity or cloud activity. The findings support containment and recovery while helping organizations maintain defensible records of the incident.
