AIX 5.3 STIG:
GEN000700
(in version v1 r3)
Title
User passwords must be changed at least every 60 days. (Cat II impact)
Discussion
Limiting the lifespan of authenticators limits the period of time an unauthorized user has access to the system while using compromised credentials and reduces the period of time available for password-guessing attacks to run against a single password.
Check Content
Check the maxage field for each user. The field represents the number of weeks a password is valid. Procedure: # /usr/sbin/lsuser -a maxage ALL If the maxage field is 0 or greater than 8 for any user, this is a finding.
Fix Text
Use the chsec command to set the maxage field to 8 for each user. # chsec -f /etc/security/user -s default -a maxage=8 # chuser maxage=8 < user id >
