Abstract:
In an organization’s of computer network, the intrusion of detection and prevention is the important one because of malicious and dedicated attacks are very high. In this paper, we describe the network infrastructure and study of a network intrusion detection system (NIDS) and network intrusion prevention system (NIPS) with syslog server in small and medium size network organization. The purposes of NIDS and NIPS are to prevent, manage and detect the unauthorized access. False negatives are obviously a problem. It is difficult to figure out what you know. In our propose system, we use other components of the security component syslog server. It will show signs of attack that the IDS is not alerting on. Snort is a popular NIDS with signature based rules for detecting of known attacks. For IPS, it is used Snort inline that acts as to protect from untrusted network. So inline prevention system is a solution of network-based security.
