Verify all system command files have no extended ACLs by running the following commands:
# aclget /etc
# aclget /bin
# aclget /usr/bin
# aclget /usr/lbin
# aclget /usr/ucb
# aclget /sbin
# aclget /usr/sbin

If any of the command files have extended permissions enabled, this is a finding.

# acledit [command-path ]/[ command-file]
