Is Cryptographic inventory Quantum Proof? Cyber Program & PQC
Verdict
Without a cryptographic inventory, no organization is quantum-ready. Inventory is the control that makes hybrid TLS, PQC, and vendor risk measurable.
Overview
A cryptographic inventory lists where cryptography runs: libraries, certificates, protocols, HSMs, SaaS features, and custom code.
It is the foundation for CBOM-style tracking, exception management, and migration roadmaps. Tools help; ownership and scope decisions matter more.
Tie inventory rows to data classification and shelf life so HNDL prioritization is explicit.
Program inventory focus: Unknown classical crypto is unmanageable quantum risk. Typical classical surfaces: Every public-key algorithm in use; Certificates, SSH keys, code-signing, tokens. Cross-read /security/program and /assessment. Educational only—not compliance advice.
Cryptographic profile
- Signatures: Every public-key algorithm in use, Certificates, SSH keys, code-signing, tokens
- Hash: Asset and software bill linkages (SBOM/CBOM)
- Public-key exposure: Unknown classical crypto is unmanageable quantum risk.
What breaks
- Spreadsheet never updated after year one
- Only counting public web certs
- Ignoring SaaS and machine identities
Mitigations
- Define scope: internet edge, remote access, identity, payments, archives
- Automate discovery where possible; interview app owners
- Link each high-value row to an owner and algorithm family
FAQ
Is inventory the same as a vulnerability scan?
No. Scans find known CVEs; inventory finds algorithms, keys, and protocols—including “secure but classical.”
How deep for year one?
Start with internet TLS, VPN/SSH, IdP tokens, code signing, and long-term encrypted archives.
