NIST SP 800-61 Rev. 3 How should teams handle communications under NIST SP 800-61 Rev. 3 incident response

Separate operational coordination, required notification, public messaging, and voluntary information sharing so each follows the right owner, audience, approval, channel, and timing.

Rev. 3 recommends advance coordination mechanisms and approved procedures. Current law, regulation, policy, contract, response plans, and information-sharing agreements determine the case-specific requirements.

Overview

NIST SP 800-61 Rev. 3 separates incident communications into four categories: , , , and . Classify the message first, then apply the correct owner, audience, approval, secure channel, timing, disclosure limit, and evidence requirement.

Question 1

How should teams handle communications under NIST SP 800-61 Rev. 3 incident response?

Use to align internal and external responders on current and planned actions. Use to inform affected customers, employees, partners, regulators, law enforcement, or others when the plan or an applicable requirement calls for it. Route through approved media procedures, and use only with designated stakeholders under response plans and information-sharing agreements.

Prepare these paths before an incident. Procedures should say what must be reported, to whom, and at what times, including initial notices and regular updates. For major incidents, update senior leadership. For malicious insider activity, involve human resources as appropriate. During recovery, continue secure status reporting and coordinate with critical suppliers under contract.

  • Coordinate internal and external incident response activities among the people who have incident response roles and responsibilities.
  • Notify affected parties when the incident response plan or an applicable law, regulation, policy, or contract requires it; verify the scope, trigger, content, recipient, route, and timing for that specific duty.
  • Use public affairs and media relations for public updates, and keep senior leadership informed on major incidents.
  • Share cyber threat information only with designated stakeholders, through secure channels, and in line with response plans, contracts, and information-sharing agreements.
  • Reassess the communication plan when facts, severity, affected parties, recovery status, legal or contractual duties, or public reporting change.
Question 2

What evidence should support communications under NIST SP 800-61 Rev. 3?

Keep one communication log that labels each entry as , , , or . Record the audience, purpose, facts known and unknown, approved content, sender, approver, channel, timestamp, sensitivity, handling restriction, and the law, regulation, policy, contract, plan, or agreement supporting the decision.

  • Stakeholder and contact matrix, communication category, decision authority, and backup contacts.
  • Notification assessment, applicable obligation, trigger time, approval, submission, and acknowledgment.
  • Status updates, approved messages, recipients, channels, timestamps, and corrections.
  • Information-sharing agreement, handling restrictions, public-affairs approval, and recovery communications.
