Write a risk people can decide on

A register is a record of uncertainty and decisions, not a catalog of security products. Start with an important business service and a plausible failure scenario.

Sample decisions

Which business service could be affected, and what evidence supports that scenario?
What decision does leadership need to make now?
Who accepts the remaining risk, for how long, and under what conditions?

Common mistakes

Listing missing tools instead of business risk scenarios.
Presenting unsupported loss estimates as measured facts.
Accepting risk without an accountable owner or expiry.

Write a risk people can decide on: A register is a record of uncertainty and decisions, not a catalog of security products. Start with an important business service and a plausible failure scenario.
Risk register entry: Repeat for each material scenario. Preserve earlier decisions so reviewers can see why the assessment changed.
One-page leadership brief: Fictional example: approve a bounded project to strengthen privileged recovery because current reset procedures can bypass strong MFA. Replace the example with your decision, not a general status summary.

Practical questions before you decide.

Who should use the Cyber Risk Register and Board Brief?

This resource is built for executives, security owners, finance, and enterprise risk teams who need a clear way to turn security guidance into owners, evidence, and next actions.
