APPLICATION-AWARE FIREWALL POLICY ENFORCEMENT BY DATA CENTER CONTROLLER

Abstract:

A Software-defined Networking (SDN) controller of data center with application-aware firewall policy enforcement is disclosed. In one example, the SDN controller receives a request to initialize an instance of an application. in response to receiving the request, the SDN controller transmits, to a firewall component positioned between an SDN gateway device of the data center and a network external to the data center, a message. In some examples, the messing includes an application signature corresponding to the instance of the application and an application firewall policy corresponding to the application signature. The message instructs the firewall component to install the application firewall policy for application to network traffic for the instance of the application.
