Discussion

Users' home directories/folders may contain information of a sensitive nature. Nonprivileged users should coordinate any information sharing with a system administrator (SA) through shared resources.

Check Content

Verify TOSS 5 limits the ability of nonprivileged users to grant other users direct access to the contents of their home directories/folders.

Ensure the user permissions on all user home directories is set to 770 permissions using the following command:

$ find $(awk -F: '($3>=1000)&&($7 !~ /nologin/){print $6}' /etc/passwd) -maxdepth 0 -not -perm 770 -ls  2> /dev/null

If there is any output, this is a finding.

Fix Text

Change the mode of interactive user's home directories to "0770." using the following command:

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

$ sudo chmod 0770 /home/smithj
