Fix Recommendation

To specify password length requirements for new accounts, edit the file "/etc/login.defs" and add or correct the following lines:

PASS_MIN_LEN 15

The DoD requirement is "15". If a program consults "/etc/login.defs" and also another PAM module (such as "pam_cracklib") during a password change operation, then the most restrictive must be satisfied.

Check Contents

To check the minimum password length, run the command:

$ grep PASS_MIN_LEN /etc/login.defs

The DoD requirement is "15".

If it is not set to the required value, this is a finding.

$ grep –E ‘pam_cracklib.so.*minlen’ /etc/pam.d/*

If no results are returned, this is not a finding.

If any results are returned and are not set to “15” or greater, this is a finding.
