Incident Response: Detecting, Containing and Recovering from Cyber Incidents
Incident Response (IR) is the structured process for detecting, containing, resolving, and following up on cybersecurity incidents. A well-prepared IR process determines the extent and duration of the damage caused by an attack.
Summary: Digital Forensics and Incident Response (DFIR) combines digital forensics (securing and analyzing evidence) with incident response (containing and resolving incidents). Following cyberattacks, DFIR teams secure evidence in a manner admissible in court, reconstruct the attack timeline, identify the initial attack vector, and assist with law enforcement. Core disciplines: Memory Forensics, Disk Forensics, Network Forensics, Malware Analysis.
