| Check Text ( C-36390r3_chk ) |
|---|
| Check user home directories for local initialization files with extended ACLs. # ls `cat /etc/passwd | cut -f 6,6 -d ":" ` | grep "/home" | sort | uniq | xargs -n1 ls -alL 2>/dev/null | egrep "\.bash_logout|\.bash_profile|\.bashrc|\.cshrc|\.dispatch|\.dtprofile|\.emacs|\.env|\.exrc|\.login|\.logout|\.profile" NOTE that the above command assumes the "base" of the user's home directory is "/home". If the system being checked uses a different "base", that "base" must be substituted for what is used in the above example. If the permissions include a '+', the file has an extended ACL, this is a finding. |
| Fix Text (F-31731r1_fix) |
|---|
| Remove the optional ACL from the file. # chacl -z [local initialization file with extended ACL] |
