# /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?

- Likelihood: H/M/L | Impact: H/M/L
- ALE: $X / year

## Blast Radius
- Data exposed (worst case): <description>
- Users affected: N
- Estimated cost: $X

## Detection
- MTTD target: X hours
- Current MTTD: X hours
- Detection rule: <name>

## Response
- IR runbook: ✅ / ❌
- Last tabletop: <date>
