Discussion

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 Content

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.

Fix Text

Change the passwords for all accounts using non-compliant password hashes.
