Title

User home directories must not have extended ACLs. (Cat III impact)

Discussion

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

Check Content

Verify user's home directories have no extended ACLs. # cut -d : -f 6 /etc/passwd | xargs -n1 ls -ld If the permissions include a "+", the file has an extended ACL, this is a finding.

Fix Text

Remove the extended ACL from the file. # getfacl [user home directory with extended ACL] Remove each ACE returned. # setfacl -d [ACE] [user home directory with extended ACL]
