What is incident response?

Also known as: IR, incident response plan

Definition

Incident response is the organized process of preparing for, detecting, containing, eradicating and recovering from security incidents, then learning from them.

Why it matters

NIST SP 800-61 Rev. 3 frames incident response within overall cybersecurity risk management using the NIST CSF functions. A written plan with named roles, contacts and practiced steps shortens the time from detection to recovery.
