| Verify all files and directories in a local interactive user home directory are group-owned by a group that the user is a member. |
Check the group owner of all files and directories in a local interactive user's home directory with the following command:
Note: The example will be for the user "smithj", who has a home directory of "/home/smithj".
$ sudo ls -lLR ///
-rw-r--r-- 1 smithj smithj 18 Mar 5 17:06 file1
-rw-r--r-- 1 smithj smithj 193 Mar 5 17:06 file2
-rw-r--r-- 1 smithj sa 231 Mar 5 17:06 file3
If any files found with a group-owner different from the home directory user private group, check to see if the user is a member of that group with the following command:
$ sudo grep smithj /etc/group
If any files or directories are group owned by a group that the directory owner is not a member of, this is a finding.
