Define External Media Restrictions

1. Begin a new restriction rule:
   1. Select PoliciesMalwareRestrictions.
   2. From the action menu
      , Add a new restriction rule.
   3. Select External Media.
2. Select the type of external media from which you want to restrict executable files from running, either Removable Drives or Optical Drives. By default, running non-malicious and unknown applications from removable and optical drives is allowed.
3. (Optional) Add Conditions to the rule. By default, a new rule does not contain any conditions.
   To specify a condition, select the Conditions tab, select the condition in the Conditions list, and then Add it to the Selected Conditions list. Repeat this step to add more conditions, as needed. You can also define new Conditions.
4. (Optional) Define the Target Objects to which to apply the rule.
   To define a smaller subset of target objects, select the Objects tab, and then enter one or more AD Users, AD Computers, AD Groups, AD Organizational Unit, Existing Endpoints, or Existing Groups in the Include or Exclude areas. The Endpoint Security Manager queries Active Directory to verify the users, computers, groups, or organizational units. The ESM Console also offers autocompletion as you type for existing endpoints and existing virtual groups.
5. (Optional) Review the rule name and description. The ESM Console automatically generates the rule name and description based on the rule details but permits you to change these fields, if needed.
   To override the autogenerated name, select the Name tab, clear the Activate automatic description option, and then enter a rule name and description of your choice.
6. Save the restrictions rule.
   Do either of the following:

   • Save the rule without activating it. This option is only available for inactive, cloned, or new rules. When you are ready to activate the rule, select the rule from the PoliciesMalwareRestrictions page and then click Activate.
   • Apply the rule to activate it immediately.

   After saving or applying a rule, you can return to the Restrictions page at any time to Delete or Deactivate the rule.
7. (Optional) To whitelist specific external media locations from your external media restriction rule, add one or more folders to the External Media Whitelist. For more information, see Manage Global Whitelists.
