What is NIST SP 800-61?

NIST SP 800-61The NIST Computer Security Incident Handling Guide, describing the four-phase lifecycle used by incident response teams in government and industry.


NIST SP 800-61 Revision 2, Computer Security Incident Handling Guide, is published by the United States National Institute of Standards and Technology and is the most widely cited reference for incident response programs. It defines a four-phase incident-response lifecycle: Preparation; Detection and Analysis; Containment, Eradication, and Recovery; and Post-Incident Activity. The guide gives detailed recommendations for building an incident-response team, classifying incidents, sharing information with internal and external parties, and continuously improving through lessons learned. It is heavily referenced by federal agencies and required by frameworks such as NIST CSF, FedRAMP, and the Cybersecurity Maturity Model Certification (CMMC).
