7 controlsFor the controls you have implemented, how much is backed by current evidence?
An assessor cannot accept a "met" claim without a current artifact (evidence older than 90 days counts as stale).
Do you have a System Security Plan (SSP)?
NIST 800-171 control 3.12.4 requires one — the assessor reads it first.
Do you have a documented POA&M tracking your open gaps?
A Plan of Action & Milestones must close eligible gaps inside the 180-day window.
