The system must use a FIPS 140-2 approved cryptographic hashing algorithm for generating account password hashes.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
|---|---|---|---|---|
| V-22303 | GEN000590 | SV-26313r2_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. |

| Check Text ( C-35959r2_chk ) |
|---|
| Verify the algorithm used for password hashing is of the SHA-2 family. # egrep "password .* pam_unix.so" /etc/pam.d/system-auth-ac # egrep "ENCRYPT_METHOD" /etc/login.defs # egrep "crypt_style" /etc/libuser.conf If any output indicates the hash algorithm is not set to sha256 or sha512, this is a finding. |
| Fix Text (F-31215r2_fix) |
|---|
| Change the default password algorithm. # authconfig --passalgo=sha512 --update NOTE: Executing the above command will also update the required parameters in /etc/login.defs and /etc/libuser.conf |
