Policy Based Security and Network Management in Computer Networks

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 management can help improve networks when the process is holistic and updated from time to time. This paper reviews literature that provides insights pertaining to policy based security and network management.
