Check Text (C-221732r991589_chk)
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.
Fix Text (F-23436r744078_fix)
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 OL 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/<file or directory>
