Fix Recommendation

From the command prompt, run the following command to set "minupperalpha=1" for the default stanza in "/etc/security/user":
# chsec -f /etc/security/user -s default -a minupperalpha=1

For each user who has "minupperalpha=0", set its "minupperalpha" to "1" by running the following command from command prompt:
# chsec -f /etc/security/user -s [user_name] -a minupperalpha=1

Check Contents

From the command prompt, run the following command to check the system default "minupperalpha" attribute value:
# lssec -f /etc/security/user -s default -a minupperalpha

The above command should yield the following output:
default minupperalpha=1

If the default "minupperalpha" value is not set, or its value is less than "1", this is a finding.

From the command prompt, run the following command to check "minupperalpha" attribute value for all accounts:
# lsuser -a minupperalpha ALL

The above command should yield the following output:
root minupperalpha=2
user2 minupperalpha=2
user3 minupperalpha=1

If any user's "minupperalpha" value is less than "1", this is a finding.
