The system must require passwords to contain at least one numeric character.

Complex passwords can reduce the likelihood of success of automated password-guessing attacks.

Check the MINDIGIT setting.

# grep ^MINDIGIT /etc/default/passwd

If the MINDIGIT setting is less than one, this is a finding.

The root role is required.

# pfedit /etc/default/passwd 

Locate the line containing:

MINDIGIT

Change the line to read:

MINDIGIT=1
