Use Case: Simulate the Risk Of Network Configuration Changes

You can use a topology model to define virtual network models based on your existing network. You can create a network model that is based on a series of modifications that can be combined and configured.

You can use a topology model to determine the effect of configuration changes on your network using a simulation.

Topology models provide the following key functionality:

  • Create virtual topologies for testing network changes.

  • Simulate attacks against virtual networks.

  • Lower risk and exposure to protected assets through testing.

  • Virtual network segments allow you to confine and test sensitive portions of your network or assets.

To simulate a network configuration change:

  1. Create a topology model.

  2. Simulate an attack against the topology model.

Creating a Topology Model

You can create a topology model to test network changes and simulate attacks.

  1. Click the Risks tab.

  2. On the navigation menu, select Simulations > Topology Models.

  3. From the Actions list, select New.

  4. Type a name for the model.

  5. Select any modifications you want to apply to the topology.

  6. Configure the tests added to the Configure model as follows pane.

  7. Click Save Model.

Create a simulation for your new topology model.

Simulating an Attack

You can simulate an attack on ports and protocols.

  1. Click the Risks tab.

  2. On the navigation menu, select Simulation >Simulations.

  3. From the Actions list box, select New.

  4. Type a name for the simulation.

  5. Select a topology model that you created.

  6. From the Where do you want the simulation to begin list, select an origin for the simulation.

  7. Add the simulation attack, Attack targets one of the following open ports using protocols.

  8. For this simulation, click open ports, and then add port 22.

  9. Click protocols, and then select TCP.

    SSH uses TCP.

  10. Click OK.

  11. Click Save Simulation.

  12. From the Actions list, select Run Simulation.

    The results column contains a list box with the date the simulation was run and a link to view the results.

  13. Click View Results.
