connected to the network in series. Its function is shown in figure 2. Figure 2: IPS In addition to IPS, some vendors have also proposed IMS (intrusion management system ). IMS is a process in which you need to consider the vulnerabilities in the network before a behavior occurs, and determine what attack behaviors may be formed and the risks of

response in the function of IDs monitoring, so as to make sure that there is an attack behavior, respond immediately, and cut off the connection actively. It is not deployed in parallel with IDs in the network, but in tandem access to the network, its function as shown in Figure 2. Figure 2:ips Function Sketch In addition to IPs, some vendors have proposed IMS (Intrusion Management

This article describes the hacker intrusion methods for the vulnerabilities in the intrusion detection system. Once the network intrusion detection system is installed, the network

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 Snort for f

to provide unlimited access to the network and obtain key data through spoofing. Without knowing it, the wireless LAN User thought that he was connected to the wireless LAN through a good signal, but he was not aware that he had been listened to by hackers. With the low cost and ease of configuration, wireless LAN is becoming increasingly popular. Many users can also set up wireless base stations (WAPS) in their traditional LAN ), the backdoor programs installed by some users on the network als

Introduction In Java Web applications, especially website development, we sometimes need to add an intrusion detection program for applications to prevent malicious refreshing, prevent Unauthorized users from repeatedly sending data to Web applications. Of course, intrusion detection can be implemented in many ways,

A good network administrator not only to manage the net, can promptly eliminate all kinds of faults, but also pay attention to network security, beware of hacker intrusion. So familiarity with common manual intrusion detection methods and commands should also be one of the basic skills of network administrators. This article introduces some UNIX common manual

. Currently, most popular intrusion detection systems have powerful string matching capabilities, which is sufficient to detect most variants of such attacks. However, some poorly-written signatures can give attackers a chance. Attackers can also make changes on this basis, which increases the defense difficulty of the intrusion
