AIX must enforce password complexity by requiring that at least one lower-case character be used.
An XCCDF Rule
Description
<VulnDiscussion>Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password complexity is one factor of several that determines how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that need to be tested before the password is compromised.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

From the command prompt, run the following command to set "minloweralpha=1" for the default stanza in "/etc/security/user":
# chsec -f /etc/security/user -s default -a minloweralpha=1
For each user who has "minloweralpha=0" set its "minloweralpha" to "1" by running the following command from command prompt:
# chsec -f /etc/security/user -s [user_name] -a minloweralpha=1
