Monitor Changes in the Virtual Environment
To secure applications and prevent threats in an environment where new users and servers are constantly emerging, your security policy must be nimble. To be nimble, the firewall must be able to learn about new or modified IP addresses and consistently apply policy without requiring configuration changes on the firewall.
This capability is provided by the coordination between the VM Information Sources and Dynamic Address Groups features on the firewall. The firewall and Panorama provide an automated way to gather information on the virtual machine (or guest) inventory on each monitored source and create policy objects that stay in sync with the dynamic changes on the network.
