Control coverage
The share of in-scope systems, users or assets that a control applies to.
Why it matters
- An incomplete asset list hides control gaps and distorts actual risk.
- Coverage is the denominator behind every control metric.
How it works
- Build a complete asset inventory.
- Define the in-scope population.
- Compare it with what the control reaches.
- Report the share and the exceptions.
