LAN security management system

Abstract

In today’s competitive era, the success of an organization solely depends on its protection of resources involved in computing. Intrusions are silent enemies that can strike any organization without warning. While these threats can go unnoticed until they cause operational disasters, there is no single “silver bullet” cure for organizational security threats. There are numerous intrusion detection systems (IDS) that work at network level which could not trace all the intrusions. So, it is required to develop integrated IDS which works at both host level and network level and reacts proactively to the threats. To develop an effective network security system for LAN includes the following components. To develop a network management system (NMS) which analyzes the traffic and throughput, predicts the link failure and monitors the availability of the device.To develop a hybrid intrusion detection system (IDS) which identifies the known and unknown malicious activities (Signature and Anomaly) and alarms the administrator.To perform port scanning which scans the activities of network devices (routes, switches, and host computer services) and report abnormal services.
