, however, proxy applications are required for different services and network bottlenecks are established. packet filtering and multiple application technologies are integrated, building a compound Firewall is a feature of domestic Firewall Products and is also the mainstream technology of firewall development in the future. In view of the data packet detection function integrated in the firewall is a good solution, it can make up for the shortcomings
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

I. 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 detecti
Intrusion detection System (IDS) is a reasonable complement to the firewall, which helps the security system to detect possible intrusion precursors and deal with network attacks. The intrusion
The Intrusion Detection System (IDS) checks all inbound and outbound network activities and confirms a suspicious pattern in which IDS can specify the attempt to access (or damage the system) someone's network attack (or system attack ). The
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
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
Intrusion detection System (IDS) is a network security device that monitors the transmission of the network in real time, alerts when suspicious transmissions are detected, or takes proactive measures. The difference between it and other network security devices is that intrusion d

In the field of network security, with the continuous "fool" of hacker application technology, IDs of intrusion detection system is gradually increasing. In a network, only effective implementation of IDs, can be acutely aware of the attacker's violations, in order to prevent them! In this paper, the concept, behavior and strategy of IDs are introduced in questio
Recently encountered many examples of server intrusion, in order to facilitate future intrusion detection and forensics, I queried some of the Linux server intrusion forensics related information, and in this summary sharing, in order to query later.General server intrusion,

The Intrusion Detection System (IDS) is a new generation of security defense technology developed over the past decade. It collects and analyzes information from several key points in a computer network or system, whether there are violations of security policies and signs of attacks. This is a dynamic security technol
Intrusion Detection and Prevention (IDP Intrusion Detection and Prevention) is a defense against Intrusion. It collects and analyzes information about several key points in a computer network or computer system, and checks whether
The well-configured Win2000 Server can defend against more than 90% of intrusions and infiltration. However, as mentioned at the end of the previous chapter, system security is a continuous process, with the emergence of new vulnerabilities and changes in server applications, the security status of the system is constantly changing. At the same time, because the attack and defense are the unity of contradic
