AIX7-00-001121 - AIX must enforce password complexity by requiring that at least one lower-case character be used.
Information
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.
Solution
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
