The password hashes stored on the system must have been generated using a FIPS 140-2 approved cryptographic hashing algorithm.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
|---|---|---|---|---|
| V-22304 | GEN000595 | SV-26316r2_rule | DCNR-1 IAIA-1 IAIA-2 | Medium |
| Description |
|---|
| Systems must employ cryptographic hashes for passwords using the SHA-2 family of algorithms or FIPS 140-2 approved successors. The use of unapproved algorithms may result in weak password hashes more vulnerable to compromise. |
