AIX7-00-001126 - AIX Operating systems must enforce a 60-day maximum password lifetime restriction - default user

Information

Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed periodically. If the operating system does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the operating system passwords could be compromised.

Solution

From the command prompt, run the following command to set 'maxage=8' (56 days) for the default stanza in '/etc/security/user':
# chsec -f /etc/security/user -s default -a maxage=8

For each user who has 'maxage' value great than '8', set its 'maxage' to '8' by running the following command from command prompt:
# chsec -f /etc/security/user -s [user_name] -a maxage=8
