| V-22303 | GEN000590 | SV-38938r1_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 that are more vulnerable to compromise. |

| Determine if the system creates password hashes using a FIPS 140-2 approved cryptographic hashing algorithm by verifying the value of pwd_algorithm in /etc/security/login.cfg. # grep pwd_algorithm /etc/security/login.cfg If the system is not configured to generate password hashes using a FIPS 140-2 approved algorithm, such as SHA256 or a successor, this is a finding. |
