Define Child Process Restrictions

The child process restriction rule is supported in Traps 3.4 and earlier releases. To restrict child processes on endpoints running Traps 4.0 and later releases, Configure Child Process Protection.
In an attempt to control an endpoint, an attacker can cause a legitimate process to spawn malicious child processes. Define a restriction rule to prevent child processes from launching from one or more processes.
  1. Begin a new restriction rule:
    1. Select PoliciesMalwareRestrictions.
    2. From the action menu manage-hidden-menu-icon.png , Add a new restriction rule.
    3. Select Child Processes (Pre-4.0 Agents).
  2. Define the behavior for child processes. By default, child processes spawned from a process are allowed.
    1. In the Select Processes search field, enter and then select the name of a process. As you type, the ESM Console offers auto-completion for any processes that match your search term.
      To modify the processes list, see View, Modify, or Delete a Process.
    2. Repeat steps a to add additional process names, as needed.
  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. To add a condition to the Conditions list, see Define Activation Conditions for a Rule on Windows Endpoints.
  4. (Optional) Define the Target Objects to which to apply the restriction rule. By default, a new rule applies to all objects in your organization.
    To define a subset of target objects, select the Objects tab, and then enter one or more Users, Computers, Groups, Organizational Unit, or Existing Endpoints in the Include or Exclude areas. The Endpoint Security Manager queries Active Directory to verify the users, computers, groups, or organizational units or identifies existing endpoints from previous communication messages.
  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.
