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-63949r1_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-52447r2_chk )
Check all password hashes in /etc/passwd or /etc/shadow begin with '$5$' or '$6$'.

Procedure:
# cut -d ':' -f2 /etc/passwd
# cut -d ':' -f2 /etc/shadow

Any password hashes present not beginning with '$5$' or, '$6$' is a finding. Any entries showing only NP, LK, or x are not findings.
Fix Text (F-54521r1_fix)
Change the passwords for all accounts using non-compliant password hashes.
