Fix Recommendation

From the command prompt, run the following command to set system wide password algorithm to "ssha512" so that it supports passwords longer than 8-character:
# chsec -f /etc/security/login.cfg -s usw -a pwd_algorithm=ssha512

For each users who have hashed passwords in "/etc/security/passwd" file that does not start with "{ssha512}", run passwd commands to reset the users' passwords so that they have to change their passwords in the next login:
# passwd [user_name]

Check Contents

From the command prompt, run the following command to check system wide password algorithm:

# lssec -f /etc/security/login.cfg -s usw -a pwd_algorithm
usw pwd_algorithm=ssha512

If the "pwd_algorithm" is not set to "ssha512", or "ssha256", this is a finding.
