nous-hermeshub /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?
