Title

All TOSS local interactive user home directories must have mode 0770 or less permissive. (Cat II impact)

Discussion

Users' home directories/folders may contain information of a sensitive nature. Non-privileged users should coordinate any sharing of information with an SA through shared resources.

Check Content

Verify the operating system limits the ability of non-privileged users to grant other users direct access to the contents of their home directories/folders. Ensure that the user permissions on all user home directories is set to 770 permissions with the following command: $ find $(awk -F: '($3>=1000)&&($7 !~ /nologin/){print $6}' /etc/passwd) -maxdepth 0 -not -perm 770 -ls If there is any output, this is a finding.

Fix Text

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 "smithj." $ sudo chmod 0770 /home/smithj
