applied data and is not included in the TCP/UDP/IP header. To achieve a higher level of security, the firewall must combine the packet filter and the application gateway. An application gateway, which is an application-specific server in which all application data must pass through the application gateway. Multiple application gateways can run on the same host, but each gateway is a separate server with its own process. However, the application gateway also has its drawbacks. First, each applic

Snort is an IDs (intrusion detection System) software developed by the U.S. Sourcefire Company under the GPL v2 Snort has three modes of operation: sniffer, packet recorder, network intrusion detection system mode. The sniffer mo

Introduction to snort Snort is a packet sniffing Based on libpcap and can be used as a lightweight network intrusion detection system (NIDS ). The so-called lightweight means that the normal operations of the network are affected as low as possible during detection. An excellent lightweight NIDS should have cross-

Because UNIX systems often undertake key tasks, they are often the first choice for intruders to attack. Therefore, intrusion detection and system security protection are one of the most important tasks of administrators. So, without the help of other tools, how can we determine the current security of the system? How

Since computers are connected through networks, network security has become a major problem. With the development of the INTERNET, security system requirements are also increasing. One of its requirements is intrusion detection systems.This article aims to introduce several common Intrusion
