NIST DE.DP-1: Detection Roles and Responsibilities
Detection is only effective when everyone knows their role. NIST Cybersecurity Framework control DE.DP-1 requires organizations to clearly define detection responsibilities across their security team to ensure accountability and prevent gaps. This foundational control eliminates confusion about who monitors what, responds to alerts, and investigates potential incidents.
What this means
DE.DP-1 mandates that your organization establish and document clear roles, responsibilities, and reporting structures specifically for your detection and monitoring functions. This includes defining who is accountable for security monitoring, threat detection, alert triage, and escalation procedures. Without well-defined detection roles, critical security events can be missed, duplicated efforts can occur, and accountability disappears when incidents happen.
How to comply
- 1.Document detection roles including security analysts, SOC staff, and management with specific responsibilities for each position
- 2.Define escalation procedures that clarify when and to whom alerts must be reported based on severity levels
- 3.Assign ownership of specific detection tools, systems, and data sources to named individuals or teams
- 4.Create a RACI matrix or responsibility chart mapping detection activities to team members
- 5.Establish performance expectations and KPIs for detection activities (e.g., mean time to detect, alert response times)
- 6.Communicate detection roles and responsibilities to all relevant personnel and conduct annual refresher training
- 7.Review and update role definitions whenever detection tools, processes, or team structure changes
Evidence auditors look for
- Detection roles and responsibilities documentation signed by security leadership
- Org chart or RACI matrix showing detection team structure and accountability
- Job descriptions or role specifications for SOC analysts, detection engineers, and incident responders
- Escalation procedures document defining alert routing and decision points
- Training records showing detection team members understand their specific responsibilities
- Audit logs or alerts showing detection activities are being performed by assigned personnel
- Change management records documenting updates to detection roles when staffing or systems change
