Verify the operating system limits the ability of non-privileged users to grant other users direct access to the contents of their home directories/folders.
Ensure that the user permissions on all user home directories is set to 770 permissions with the following command:
$ find $(awk -F: '($3>=1000)&&($7 !~ /nologin/){print $6}' /etc/passwd) -maxdepth 0 -not -perm 770 -ls
If there is any output, this is a finding.
