The AIX user home directories must not have extended ACLs.

Excessive permissions on home directories allow unauthorized access to user files.

Verify user home directories have no extended ACLs using command:

# cat /etc/passwd | cut -f 6,6 -d ":" | xargs -n1 aclget * * ACL_type AIXC * attributes: base permissions owner(root): rwx group(system): r-x others: r--- extended permissions disabled

If extended permissions are not disabled, this is a finding.

Remove the extended ACL from the user home directory and disable extended permissions: # acledit <directory>
