GV.PO-02 says policy for managing cybersecurity risks is reviewed, updated, communicated and enforced to reflect changes in requirements, threats, technology and organizational mission. In other words, the policy you wrote last year needs a plan for staying true.
What good looks like
A review date on every policy and a short list of events that trigger an early review. Updates come from real inputs: risk results, new legal duties, new tools and business changes. After each update, staff are told and re-acknowledge.
How to implement it
- Set a fixed review interval, commonly yearly.
- Define triggers. NIST's examples include changes in law, adopting new technology such as artificial intelligence, acquiring a business, and new contract requirements.
- Use risk results to test the policy: if a risk keeps recurring, the policy may not hold it at an acceptable level.
- Publish a short change summary with every update.
- Re-run acknowledgment for material changes.
Evidence to collect
- Policy version history with change notes.
- Review meeting records and trigger events that caused an update.
- Communication and acknowledgment records after each update.
Common gaps
- Review dates pass with no one noticing.
- A new technology, such as an AI coding assistant, is in use for months before the policy mentions it.
- Updates are published silently.
Quick check
What should trigger an off cycle review?
A new law or contract clause, a major incident, a new class of technology in use, or a business change such as an acquisition.

The CSF is voluntary guidance. There is no CSF certification, so this post describes how to work toward the outcome, not how to pass an audit.
