NIST 800-171 3.6.3 (IR.L2-3.6.3): Incident Response Testing
Test the organizational incident response capability.
CMMC Level 2 practice IR.L2-3.6.3
What 3.6.3 means in practice
Test the incident response capability, for example with a tabletop exercise, a simulation or a full drill, and feed what you learn back into the plan. Tests that find nothing to fix are rare, so assessors expect to see lessons learned.
SPRS points and the CMMC POA&M
- CMMC Level 2 practice
- IR.L2-3.6.3
- SPRS points
- 1 point. When it is not met, the DoD Assessment Methodology subtracts 1 from the score of 110.
- CMMC POA&M
