The CISO's Three Questions Every Quarter

CISOs ask different questions than engineers. The right three drive the right work.

Q1: What changed in our threat model

Threat models drift. New products, new partners, new regulations move the threat surface every quarter.

Honest answer: changes you should have addressed but did not. Vague answer: nothing changed.

Q2: What did we discover too late

Q3: What is one less thing we own

Less surface = less risk. Decommissioned services; archived accounts; removed dependencies.

Honest answer: at least one thing per quarter you actively removed.

How to answer well

Ahead of the meeting: pick three concrete examples per question; do not improvise.

In the meeting: own the gaps; propose dated next steps.

Antipatterns

What to do this week

Three moves. (1) Pick one production system to apply this pattern to first. (2) Measure the security signal before/after. (3) Document the gap and write a follow-up ticket so the program stays alive between quarterly reviews.
