Check user home directories for local initialization files with extended ACLs. # for HOMEDIR in $(cut -d: -f6 /etc/passwd); do find ${HOMEDIR} -type f -name '\.*' | xargs ls -ld | grep '\+'; done 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.
