Control guide — plain-English, per NIST SP 800-53
SC-13 (Cryptographic Protection) requires the system to use cryptography that meets the laws and standards for its purpose — for U.S. federal Moderate systems that means FIPS-validated (Federal Information Processing Standards) algorithms and modules for the protections you depend on. The control names which cryptography is used and why.
What good looks like
- Identify every place cryptography is required — data in transit, data at rest, and authentication.
- Use approved, validated algorithms and modules (FIPS 140-validated) for those uses.
- Avoid weak or deprecated algorithms such as MD5, DES, SSLv3, or early TLS.
- Document the cryptographic uses and configure the operating-system (OS) crypto policy to enforce the approved set.
Framework mapping
- NIST CSF 2.0 — PR.DS-02 — Data are protected using validated cryptographic mechanisms
- CIS Controls v8 — Control 3 — Data Protection (encrypt data with approved algorithms)
How to move it toward Implemented
- SSH provides strong crypto for the admin channel, but SC-13 is not fully met on this asset.
- Two gaps: no FIPS-validated cryptography is specified — enable the OS crypto policy / FIPS mode and record the modules in use — and the DVWA app has no TLS at all (fix with HTTPS, see SC-8).
- Document the approved algorithm set (and disable weak ciphers in
sshd_config), then attach it naming SC-13 to progress from partial toward 'Completed'.
