| Setting the most restrictive default permissions ensures that when new accounts are created, they do not have unnecessary access. |
| ℹ️ Check |
|---|
| Verify the SUSE operating system defines default permissions for all authenticated users in such a way that the users can only read and modify their own files. Check the system default permissions with the following command: > grep -i "^umask" /etc/login.defs UMASK 077 If the "UMASK" variable is set to "000", the severity is raised to a CAT I, and this is a finding. If the value of "UMASK" is not set to "077", or "UMASK" is missing, this is a finding. |
| ✔️ Fix |
|---|
| Configure the SUSE operating system to define the default permissions for all authenticated users in such a way that the users can only read and modify their own files. Add or edit the "UMASK" parameter in the "/etc/login.defs" file to match the example below: UMASK 077 |
