# Which CSIRT roles should teams define under NIST SP 800-61 Rev. 3?

Which CSIRT roles should teams define under NIST SP 800-61 Rev. 3? Clear, source-linked guidance with practical evidence checks, owner decisions, and implementation steps.

*FAQ* *GLOBAL* *NIST SP 800-61 Rev. 3*

## NIST SP 800-61 Rev. 3 incident response Which CSIRT roles should teams define under NIST SP 800-61 Rev. 3

A standalone answer for teams deciding how csirt roles should be scoped, owned, evidenced, and reviewed under NIST SP 800-61 Rev. 3.

Each answer is standalone, including the decision context, owner mapping, evidence gate, and next-step trigger so users can apply it in one pass.

Define csirt roles as the people and functions that make incident response work under NIST SP 800-61 Rev. 3. A practical CSIRT should name leadership, incident handlers, technology professionals, legal, public affairs and media relations, human resources, physical security and facilities management, asset owners, and any third parties that help perform incident response.

## Which CSIRT roles should teams define under NIST SP 800-61 Rev. 3?

Define csirt roles by naming the operating role, scope, authority, evidence artifact, and source-linked requirement before using it in a live workflow.

NIST SP 800-61 Rev. 3 says incident response roles and responsibilities can include leadership, incident handlers, technology professionals, legal, public affairs and media relations, human resources, physical security and facilities management, asset owners, and third parties.

- Leadership oversees incident response, allocates funding, and may approve high-impact response actions.
- Incident handlers verify incidents, collect and analyze data and evidence, prioritize response activities, and limit damage.
- Technology professionals, legal, public affairs and media relations, human resources, and physical security and facilities management support response and recovery as needed.
- Asset owners help set response and recovery priorities for affected assets and receive status updates.
- Third parties, such as MSSPs, cloud service providers, ISPs, business partners, and law enforcement agencies, may support incident response when the organization needs them.

## What evidence should support csirt roles under NIST SP 800-61 Rev. 3?

Use the NIST SP 800-61 Rev. 3 decision path to make this topic review-ready: document who is responsible, what authority each role has, what evidence proves the assignment, and when the assignment must be reviewed.

- Write the role, authority, and backup for each incident response function.
- Document which actions leadership can approve and which actions incident handlers can take directly.
- Record the external parties that may be involved, such as providers, business partners, or law enforcement.
- Capture the status-update and escalation path for asset owners and senior leadership.
- Review the assignments after major incidents or organizational changes.
