The AIX root accounts home directory must not have an extended ACL.

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

Verify the "root" account's home directory has no extended ACL using command:

# aclget ~root * * ACL_type AIXC * attributes: base permissions owner(root): rwx group(system): --- others: --- extended permissions disabled

If extended permissions are enabled, the directory has an extended ACL, and this is a finding.

Remove the extended ACL from the "root" account's home directory using command: # acledit ~root

Change extended attributes to disabled.
