What is Incident Response?
Also known as: DFIR
Incident response is the organized process of preparing for, detecting, containing, eradicating, and recovering from cybersecurity incidents, and digital forensics is the discipline of collecting and analyzing evidence to understand what happened. Together, DFIR matters because a structured response limits damage, preserves evidence, and speeds recovery after an attack.
Example
After detecting ransomware, a team isolates affected hosts, preserves disk images for forensic analysis, and restores clean systems from backups.
