AIX7-00-001132 - AIX must prevent the use of dictionary words for passwords.

Information

If the operating system allows the user to select passwords based on dictionary words, then this increases the chances of password compromise by increasing the opportunity for successful guesses and brute-force attacks.

Solution

From the command prompt, run the following command to set "dictionlist" attribute for the default stanza in "/etc/security/user":
# chsec -f /etc/security/user -s default -a dictionlist="/etc/security/ice/dictionary/English"

From the command prompt, run the following command to set "dictionlist" attribute for users who have an empty "dictionlist" attribute:
# chsec -f /etc/security/user -s [user_name] -a dictionlist="/etc/security/ice/dictionary/English"
