Software-defined protection
Software-defined Protection (SDP) is a computer networking security architecture and methodology that combines network security devices and defensive protections that leverage both internal and external intelligence sources. An SDP infrastructure is designed to be modular, scalable and secure. The SDP architecture partitions the security infrastructure into three interconnected layers. The Enforcement Layer inspects traffic and enforces protection within well-defined network segments. The Control Layer generates security policies and deploys those protections to enforcement points. The Management Layer orchestrates the infrastructure and integrates security with business processes. The SDP architecture supports traditional network security and access control policy requirements, as well as the threat prevention required for enterprises implementing technologies such as mobile computing and Software-defined Networking (SDN).
==Enforcement Layer==
The Enforcement Layer of SDP enables organizations to design segmented networks, implement physical and virtual security enforcement points based upon that segmentation, and execute the protection logic for the prescribed network segments.
SDP incorporates the principal of segmentation into the Enforcement Layer. Segmentation divides a network into compartments that have different security characteristics. Based upon segment requirements, security controls are established for threat containment and recovery. Enforcement points, or platforms for executing protections, must then be implemented at the boundaries of the segments to enforce the defined protection logic. Enforcement points may be implemented as network security gateways, host-based software, mobile device applications, or virtual machines in the cloud.
