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.
