Equation #23 · Chapter 11

Audit Defense Score D_audit

D_{audit} = \frac{Certifications \times Scope}{Auditor\_Fear}

Audit Defense Score

D_audit · Ch 11

(Certifications × scope) ÷ auditor fear. Make saying NO riskier than saying YES.

Worked example — Security review, and a nervous auditor

You carry SOC 2 Type II and a current pen test, and you inherit your cloud provider's FedRAMP controls — three real, independent attestations. They cover about 6 of 10 of what's in scope. The auditor has been burned before and it shows.

It came out at 6.0. Green — rubber-stamp territory.

Leave that auditor's fear at 8 instead of working it down and the identical paperwork reads 2.25 — yellow, and a quarter in review. By then the certifications are fixed and the fear isn't. Bring the comparison matrix; make saying no the riskier option.

Your turn — change one number

Real independent attestations you carry (count — inherited controls count)3

Scope coverage (1–10)6

Auditor fear (1–10)3

Result6.00

Green. Rubber stamp. Bring the comparison matrix anyway.
