Adding an object to the User-Defined Suspicious Objects List does not terminate any active processes or connections to the object. To terminate active processes, ensure that you also trigger the Terminate response.

Procedure

  1. After identifying the object to block, access the context or response menu and click Add to Block List.
    The Add to Block List Task screen appears.
  2. Confirm the targets of the response.
    Trend Vision One can add the following types of objects to the User-Defined Suspicious Objects List on selected servers:
    • File SHA-1
    • IP address
    • URL
    • Domain
    • Email address
    		  
  3. 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 Add to Block List from the Action drop-down list.

      The Task Status indicates whether the managing server was able to successfully receive the command but does not necessarily mean that the target servers already synchronized the User-Defined Suspicious Objects List to all related products.
      Adding an object to the User-Defined Suspicious Objects List does not terminate any active processes or connections to the object. To terminate active processes, ensure that you also trigger the Terminate response.
