Check Text ( C-42370r1_chk )
Check all system command files have no extended ACLs.

# ls -lL /etc /bin /usr/bin /usr/local/bin /sbin /usr/sbin /usr/local/sbin

If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.
