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

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

Check the MINUPPER setting.

# grep ^MINUPPER /etc/default/passwd

If MINUPPER is not set to 1 or more, this is a finding.

The root role is required. # pfedit /etc/default/passwd

Locate the line containing:

MINUPPER

Change the line to read:

MINUPPER=1
