Verify all files and directories contained in a local interactive user home directory, excluding local initialization files, have a mode of "0750".
Check the mode of all non-initialization files in a local interactive user home directory with the following command:
Files that begin with a "." are excluded from this requirement.
Note: The example will be for the user "smithj", who has a home directory of "/home/smithj".
# ls -lLR /home/smithj
-rwxr-x--- 1 smithj smithj 18 Mar 5 17:06 file1
-rwxr----- 1 smithj smithj 193 Mar 5 17:06 file2
-rw-r-x--- 1 smithj smithj 231 Mar 5 17:06 file3
If any files are found with a mode more permissive than "0750", this is a finding.
