Computer networks are ubiquitous in nature with a plethora of networking models that are suited to different organizations. However, security has been a concern in such networks besides managing network effectively. Mostly network security is based on the needs of the organization which used the network for secure communications. However, the actual implementation of security is achieved by defining policies that guide the policy management tool to take expert decisions. The policies when defined perfectly, the security can be most effective. Network administrators depend on traditional tools that can be used to monitor happenings in the network. However, when there are plenty of messages in the reports and network administrators need time to analyze and made decisions, they cannot prevent damage that has been caused already. Therefore a real time approach is desired for both network management and security in computer networks. We believe that policy based security and network mana.

Network Functions Virtualization (NFV) and Software Defined Networking (SDN) make it easier for security administrators to manage security policies on a network system. However, it is still challenging to map high-level security policies defined by users into low-level security policies that can be applied to network security devices. To address this problem, we introduce a framework for effectively managing user-defined security policies for network security functions based on standard interfaces that are currently being standardized in an IETF working group. To show the feasibility of the proposed framework, we implemented a prototype based on the RESTCONF protocol and showed that the proposed framework can be applied in real-world scenarios for network separation, DDoS mitigation and ransomeware prevention.
