Description
To enforce the use of complex passwords, minimum numbers of characters of different classes are mandated. The use of complex passwords reduces the ability of attackers to successfully obtain valid passwords using guessing or exhaustive search techniques. Complexity requirements increase the password search space by requiring users to construct passwords from a larger character set than they may otherwise use.

Check Text ( C-36899r1_chk )
NOTE: This will always require a manual review. More importantly, AIX by default does not currently support enforcement of upper and lower case characters in passwords. This is considered a local, written policies check. Consult site documentation for the local policy specifying non-use of mixed case characters in passwords. If it does not, this is a finding.

Fix Text (F-33092r1_fix)
No Fix. AIX does not provide this functionality out of the box.
