Is Crypto incident response Quantum Proof? Cyber Program & PQC
Verdict
Incident response for cryptographic break or mass key compromise is part of quantum readiness. Practice rotation and revocation before a CRQC—or a classical breach of a root key—forces an untested fire drill.
Overview
Crypto incidents include CA compromise, leaked code-signing keys, and widespread weak-algorithm exposure.
Quantum changes impact models (forgery at scale) but runbooks look like extreme PKI and identity incidents.
Program inventory focus: Broken classical keys require coordinated rotation across trust domains. Typical classical surfaces: Compromised CA/IdP/code-signing keys; Mass certificate revocation events. Cross-read /security/program and /assessment. Educational only—not compliance advice.
Cryptographic profile
- Signatures: Compromised CA/IdP/code-signing keys, Mass certificate revocation events
- Hash: Forensic disk and log hashes
- Public-key exposure: Broken classical keys require coordinated rotation across trust domains.
What breaks
- No owner for emergency CA rollover
- Revocation soft-fail everywhere
Mitigations
- Runbooks for IdP, CA, code-signing, and VPN gateways
- Tabletop annually
- Out-of-band comms paths that do not depend on the broken trust anchor
FAQ
Is this only for quantum?
No—classical key compromise already justifies the same readiness.
Include legal?
Yes for customer notification and regulatory triggers—coordinate in advance.
