What it means
Control implementation evidence demonstrates that a control is designed, configured, operated, monitored, and corrected as claimed within a defined scope and time period.
Why it matters
A policy or screenshot can show intent or a moment in time but rarely proves sustained effectiveness by itself.
Practical focus
- Define the claim the evidence must support
- Use several evidence types where necessary
- Preserve scope, time, source, and ownership
- Verify exceptions and corrective actions
Common mistakes
- Collecting artifacts without a control claim
- Using stale screenshots
- Confusing implementation with effectiveness
- Producing evidence that cannot be reproduced
