PHTN-40-000187 - The Photon operating system must define default permissions for all authenticated users in such a way that the user can only read and modify their own files.

Information

Setting the most restrictive default permissions ensures that when new accounts are created they do not have unnecessary access.

Solution

UMASK 077
