Snort has always been the leader of network intrusion Detection (IDS) and intrusion prevention tools (IPS) and, as the open source community continues to evolve, Sourcefire for its parent company (for years, Sourcefire offers a full-featured commercial version of vendor support and instant updates snort , while still offering a limited free version of
the hybrid mode, the libpcap or winpcap function is used to capture data packets from the network based on different operating systems. The captured data packets are then sent to the package decoder for decoding.
Run Snort:It is mainly achieved through the coordination of various plug-ins to make it powerful, so it is also important to select the appropriate database, Web server, graphics processing program software and version during deployment.
Disadvantages:The reason why
packets and some packet attributes, and there is no specific rule association mechanism, Snort can only detect attacks with coarse lines. Currently, the mainstream commercial NIDs products have adopted meticulous application-layer protocol analysis technology. The application-layer protocol analysis technology not only greatly improves the accuracy and efficiency of detection, but also brings the exception detection capability based on protocol analy
systems (IDS/IPS) are composed of hardware and software. If you want to build a high-performance intrusion detection and defense system, the hardware and software required to form IDS/IPS must be prepared by ourselves! Without any of the two, it is impossible to complete the task of creating an intrusion detection and defense system.

Nowadays, enterprises have many choices to protect the network from external attacks. For example, firewall is a good choice. In most cases, it can distinguish abnormal data packets, therefore, we can take timely measures to prevent problems before they happen.
However, for most enterprises, IDS is the best choice to completely isolate potential threats. Intrusion detection and defense are generally used together with the enterprise's first firewall, which includes the following two basic layers
