You can take preventive isolation measures on compromised endpoints that may pose a security risk to your network using context menus on the Trend Vision One console.

This task is supported by the following services:
  • Trend Vision One
    • Windows agent
    • Linux agent
    • Mac agent
  • Apex One as a Service
    • Windows agent
  • Trend Cloud One - Endpoint & Workload Security
    • Windows agent
    • Linux agent
    • Mac agent
Note
Note
Taking certain response actions on critical endpoints could obstruct key operations or services. For critical devices, Trend Micro recommends excluding the endpoints from certain response actions instead.
To allow network traffic on isolated critical endpoints, such as DNS servers, proxy servers, or VPN routers, you can add an inbound or outbound network traffic exception for the IP addresses of the specified endpoints.

Procedure

  1. After identifying the endpoint to isolate, access the context or response menu and click Isolate Endpoint.
    The Isolate Endpoint Task screen appears.
  2. Confirm the targets of the response.
  3. (Optional) Specify a Description for the response or event.
  4. Click Create.
    Trend Vision One creates the task and displays the current task status in Response Management.
  5. Monitor the task status.
    1. Open Response Management.
    2. (Optional) Locate the task using the Search field or by selecting Isolate Endpoint from the Action drop-down list.
    3. View the task status.
      • Pending approval (pending-approval.jpg) (if applicable): The automated response task was created on the Workbench app and is waiting for approval
      • Rejected (rejected.jpg) (if applicable): The automated response task created on the Workbench app was rejected
      • In progress (in-progress.jpg): Trend Vision One sent the command and is waiting for a response.
      • Queued (queued.jpg): The managing server queued the command because the agent was offline.
      • Successful (successful.jpg): The command was successfully executed.
      • Unsuccessful (error.jpg): An error or time-out occurred when attempting to send the command to the managing server, the agent is offline for more than 24 hours, or the command execution timed out.
      Important
      Important
      The Task status indicates whether the managing server was able to successfully receive and execute the command. If the command target is a Security Agent, the Task status does not necessarily indicate whether the target Security Agent or object successfully executed the command.
    After resolving the security issue on the isolated endpoint, you can restore network connectivity using the options button (options-icon.jpg) in the Response Management app.
