NETWORK VULNERABILITY: A REVIEW

Abstract

Network security consists of the policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Securing and protecting a computer network from possible attacks or intrusions is very difficult task. Intruders can attack vulnerable systems and networks and compromise data as well as critical systems. But by the review and analysis of the existing vulnerabilities using some of the available technological approaches, general point solutions are acquired, giving clues for strategic network protections. The research aim at x-raying some of the available network vulnerability technological approaches and some models which can be implemented to detect and measure intrusion tendencies of a network in order to ensure a secure network. The methodology adopted are; (1) Extensive review of relevant literatures on network security, network policy, and methods used in attacking computer network, (2) Analysis of vulnerability types, expected vulnerabilities in network and scanning tools to detect vulnerabilities. The result of the review and analysis x-raying some of the available network vulnerability technological approaches and models which can be implemented to detect and measure intrusion tendencies of a network in order to ensure a secure network.
