NIST SP 800-61 Rev 3: Incident Response as a CSF 2.0 Community Profile

What Rev 3 Covers

• Maps prior lifecycle phases to CSF 2.0 Functions (e.g., Preparation aligns with Govern/Identify/Protect; Detection & Analysis with Detect; Containment/Eradication/Recovery with Respond/Recover)
• Two Community Profile tables: Preparation & Lessons Learned (including ID.IM improvement) and Incident Response (Detect, Respond, Recover)
• Priority labels (High/Medium/Low) as starting points organizations should customize

Why It Matters

Teams googling “NIST IR lifecycle” still expect Rev 2 phases. Rev 3 expects CSF language and continuous improvement via ID.IM — aligning IR with the rest of cybersecurity risk management, not a standalone binder.

• ThreatHawk SIEM and Agentic SOC AI — Detect and Respond operations
• Compliance Standards Automation — IR plan and exercise evidence mapped to CSF Subcategories and 800-53 IR

Frequently Asked Questions

Is the classic four-phase IR lifecycle gone?

SP 800-61 Rev 3 re-frames recommendations around CSF 2.0 Functions. Organizations may still use a lifecycle model that fits them; Rev 3 maps older phases to CSF outcomes.

Is 800-61 Rev 3 only for federal agencies?

It is written for most organizations. The Community Profile is a starting point to customize by sector, size, and risk.

How does this relate to the CSF Respond function guide?

Complementary. The CSF Respond page explains RS Categories; SP 800-61 Rev 3 provides IR-focused recommendations across the CSF Core.
