Isolate endpoints in Nebula

Isolate endpoints to stop threats from spreading between endpoints by restricting their communication or access. An isolated endpoint can still communicate with the console and run Nebula processes.

Types of isolation

There are three different isolation types. They may be enabled separately or combined to increase isolation. The three isolation types are:

• Network Isolation: Prevent the endpoint from communicating with other devices on your network.
• Process Isolation: Restrict which processes can run on the endpoint and prevent processes from interacting.
• Desktop Isolation (Windows only): Prevent end users from accessing the endpoint.

With Process Isolation enabled, only Privileged Processes are allowed to launch on the endpoint. Privileged Processes belong to one of these types:

• Predefined (hardcoded) processes: Currently there are two predefined processes: CONSENT.exe, necessary to execute UAC elevated processes; and CSRSS.EXE which is a critical system process.
• Processes digitally signed by Malwarebytes: These are allowed to run unrestricted on isolated endpoints.
• Processes spawned by other Privileged Processes: A process with a privileged parent process is also privileged. Privileged child process may create more privileged child processes.

Isolate endpoints

Before you can isolate an endpoint, the policy settings must be enabled. For more information, see Endpoint Detection and Response policy settings in Nebula. 

To isolate an endpoint:

1. On the left navigation menu, go to Manage > Endpoints, then select an endpoint to isolate. 
2. Click the Actions menu on the top right. Select Isolate endpoint(s).
3. Confirm the types of isolation you want, and click Yes. All isolation types are enabled by default. To change the isolation type applied to an endpoint, you must remove the isolation and then apply the new isolation types.
   

Remove endpoint isolation

You can remove endpoints from isolation on the Endpoints screen. Removing an endpoint from isolation turns off all isolation types.

1. Select an isolated endpoint. 
2. Click the Actions menu and select Remove Isolation.
3. The endpoint will be removed from isolation and automatically reboot. You may lose any unsaved work.
