| Verify all files and directories in a local interactive user's home directory have a valid owner. Check the 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 /home/smithj -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 smithj 231 Mar 5 17:06 file3 If any files or directories are found without an owner, this is a finding. |

| Either remove all files and directories from the system that do not have a valid user, or assign a valid user to all unowned files and directories on RHEL 7 with the "chown" command: Note: The example will be for the user smithj, who has a home directory of "/home/smithj". $ sudo chown smithj /home/smithj/ |
