The ALG providing encryption intermediary services must use NIST FIPS-validated cryptography to implement encryption services.

Discussion

Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The network element must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated.

This requirement applies only to ALGs that provide encryption intermediary services (e.g., HTTPS, TLS, or DNSSEC).

This requirement also applies to Zero Trust initiatives.

Check

If the ALG does not provide encryption intermediary services (e.g., HTTPS, TLS, or DNSSEC), this is not applicable.

Verify the ALG uses NIST FIPS-validated cryptography to implement encryption services.

If the ALG does not use NIST FIPS-validated cryptography to implement encryption services, this is a finding.

Fix

If encryption intermediary services are provided, configure the ALG to use NIST FIPS-validated cryptography to implement encryption services.
