Hello,

You can determine the level of interaction that you want users to have on the Symantec Endpoint Protection client. Choose which features are available for users to configure. For example, you can control the number of notifications that appear and limit users' ability to create firewall rules and virus and spyware scans. You can also give users full access to the user interface.

The features that users can customize for the user interface are called managed settings. The user does not have access to all the client features, such as password protection.

To password-protect the client

1. In the console, click Clients.

2. Under Clients, select the group for which you want to set up password protection.

3. On the Policies tab, under Location-independent Policies and Settings, click General Settings.

4. Click Security Settings.

5. On the Security Settings tab, choose any of the following check boxes:

   • Require a password to open the client user interface

   • Require a password to stop the client service

   •  Require a password to import or export a policy

   • Require a password to uninstall the client

6. In the Password text box, type the password.

   The password is limited to 15 characters or less.

7. In the Confirm password text box, type the password again.

8. Click OK.
