To configure the number of retry prompts that are permitted per-session: Edit the 'pam_pwquality.so' statement in '/etc/pam.d/system-auth' to show 'retry=3', or a lower value if site policy is more restrictive. The DoD requirement is a maximum of 3 prompts per session.


Parameter:

[3_attempts]


Technical Mechanism:

Setting the password retry prompts that are permitted on a per-session basis to a low value requires some software, such as SSH, to re-connect. This can slow down and draw additional attention to some types of password-guessing attacks. Note that this is different from account lockout, which is provided by the pam_faillock module.
