How to Restrict Helpdesk User Permissions for Enhanced Security?

To ensure that only authorized personnel can access the list views in our SharePoint-based helpdesk system, you can restrict regular users by creating a custom SharePoint helpdesk permissions level. Here’s a step-by-step guide to setting up these permissions.

1. Open the site hosting the Office 365 ticketing system, click on the settings gear, and then select Site Permissions.

2. Click on Advanced Permissions Settings.

3. Click on Permission Levels.

4. Click on Add a Permission Level.

5. Enter a name and description, and select the permissions shown in the image below.

6. Click on Create.

7. You can create a new SharePoint group and assign the newly created permission level to it.

8. Add everyone to that group, which means all users.

This will prevent anyone from viewing any list views.

For this to work, please keep the following in mind:

1. Remove everyone or all regular users from any other groups.
2. Ensure that admins remain in the Owners or Members group.
