Fix Recommendation

Change the mode of interactive user's home directories to "0770". To change the mode of a local interactive user's home directory, use the following command:

Note: The example will be for the user "wadea".

$ sudo chmod 0770 /home/wadea

Check Contents

Verify the assigned home directory of all local interactive users has a mode of "0770" or less permissive using the following command:

Note: This may miss interactive users that have been assigned a privileged user identifier (UID). Evidence of interactive use may be obtained from a number of log files containing system logon information.

$ sudo ls -ld $(awk -F: '($3>=1000)&&($7 !~ /nologin/){print $6}' /etc/passwd)

drwxrwx--- 2 wadea admin 4096 Jun 5 12:41 wadea

If home directories referenced in "/etc/passwd" do not have a mode of "0770" or less permissive, this is a finding.
