Whitelist a Network Folder

To prevent attack scenarios that are based on writing malicious executable files to remote folders, you can create a restriction rule to block all executable files run from specific folders. To enable executable files to run from known trusted network locations, you can create a
Network Folder Behavior
restriction rule to whitelist the file or remote folder path.
When you enable this rule, Traps blocks all executable files that run from network locations except for those expressly whitelisted in the rule. When a user attempts to open an executable file from a network folder that is not specified in the whitelist, Traps blocks the attempt and reports the security event to the ESM Server.
  1. Begin a new restriction rule:
    1. Select
      Policies
      Malware
      Restrictions
      .
    2. From the action menu ,
      Add
      a new restriction rule.
    3. Select
      Network Folder Behavior
      .
  2. Select the option to
    Restrict file execution from all network folders except the locations listed below
    .
  3. Click the add folder icon , to
    Add
    the file or folder path in uniform naming convention (UNC) format.
    To whitelist a folder, you must terminate the path with a wildcard. For example,
    \\networkpath\temp\*
    matches any file launched from the
    \\networkpath\temp\
    folder or subfolder).
    For additional syntax examples, see Wildcards and Variables in Policy Rules.
  4. Repeat the previous step to add multiple paths as needed.
  5. (
    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.
  6. (
    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.
  7. (
    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.
  8. 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
      Policies
      Malware
      Restrictions
      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.
