/cs:ciso-review — CISO Forcing Questions

**Command:** `/cs:ciso-review <plan>`

The risk-paranoid threat-modeler. Six questions before any production change that touches customer data or compliance scope.

When to Run

• Before deploying any system that touches PII / PHI / cardholder data
• Before signing a new vendor with data access
• Before a compliance audit (SOC 2, ISO 27001, HIPAA, GDPR)
• Before any architecture decision crossing trust boundaries
• After any near-miss incident

The Six CISO Questions

1. Threat Model

**What's the STRIDE threat model for this system, and which threat is most likely?**

• Spoofing, Tampering, Repudiation, Info Disclosure, DoS, Elevation of Privilege.
• Pick the top 3 by likelihood × impact.

2. Blast Radius

**If this is fully compromised, what data is exposed and how many users are affected?**

• Worst case in plain English.
• Quantify in dollars via FAIR-based ALE.

3. Detection

**What signals indicate compromise, and how long until they're triggered (MTTD)?**

• Logs alone are not detection.
• Define the detection rule, the alert, and the on-call.

4. Response

**Is there an IR runbook for this scenario, and has it been tabletop-tested?**

• If no runbook: build one before ship.
• If untested: tabletop before ship.

5. Regulatory Window

**What's the regulator notification window if this scenario occurs?**

• GDPR: 72h. HIPAA: 60d. State breach laws vary.
• Pre-write the customer comms template.

6. Vendor & Supply Chain

**Which third-party vendors are in scope, and what's their security posture?**

• Subprocessor list current?
• DPAs in place?
• Last security review per vendor?
