DECOUPLING HARDWARE AND SOFTWARE COMPONENTS OF NETWORK SECURITY DEVICES TO PROVIDE SECURITY SOFTWARE AS A SERVICE IN A DISTRIBUTED COMPUTING ENVIRONMENT

A computer system and method provides cloud-based network security software as a service in a distributed computing environment. A computer system executing on a portion of hardware computing resources associated with the distributed computing environment receives a security service request from a customer platform device external to the distributed computing environment, the request identifying a customer platform asset within the distributed computing environment and instructing that a security service selected by the customer platform device be provided to the identified customer platform asset. In response to receiving the security service request, a network security software component associated with the selected security service on one or more virtual machines within the distributed computing environment is executed to provide the selected security service to the identified customer platform asset. The one or more virtual machines are deployed on a set of the hardware computing resources associated with the distributed computing environment.
