Compare two risk register snapshots and report what moved

Why it matters

A risk register is only useful if someone watches how it changes. NIST SP 800-39 makes monitoring risk one of its four core risk-management activities, and NIST IR 8286 describes cybersecurity risk registers being reviewed and rolled up into enterprise risk reporting. In practice the quarterly review often shrinks to one chart: the average score went down, well done. That chart can hide the quarter's most important fact. One risk can climb to the maximum while others fall, a risk marked 'treating' can be getting worse, a risk can drop out of the register with no record of why, or a score can…

What you'll learn

Steps in this lab

  1. Monitoring means comparing, not averaging
  2. Two quarters of the register
  3. Write the snapshot diff
  4. Run it: the average fell, the quarter did not improve
  5. Make it the standing quarterly report
