Title: Introduction to Intrusion detection technology time: 2004-06-13 Source: http://www.meiclub.com/Abstract with the development of computer technology, especially network, computer system has been developed from independent host to complex and interconnected open system, This has brought great convenience to people

(2) related firewalls: devices with network boundaries can be attacked by themselves, and some attacks are poorly protected. Not all threats come from outside the firewall. (3) Easy

Introduction to Intrusion Detection Systems Chapter 1 concept of Intrusion Detection System As more and more companies transfer their core services to the Internet, network security is an unavoidable problem. Traditionally, companies generally adopt firewalls as the firs

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

With the development of network security technology, apart from firewall and anti-virus system protection, intrusion detection technology has become an effective way to defend against hacker attacks. Although the intrusion detection technology is still evolving, the market f

With the increasing risk coefficient of network security, firewalls, once the most important security defense means, cannot meet people's requirements for network security. As a supplement to firewalls and their benefits, IDS (Intrusion Detection System) can help network systems quickly detect attacks, it extends the security management capabilities of

With the increasing of the risk coefficient of network security, the firewall, which used to be the main security precaution, can not meet the need of the network security. As a useful complement to the firewall, IDS (Intrusion detection System) can help the network system to quickly detect the occurrence of the attack

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

In Java Web applications, especially Web site development, we sometimes need to add an intrusion detection program to the application to prevent the malicious refresh of the ability to prevent illegal users from constantly sending data to the Web application. Of course, intrusion detection can be implemented in many wa

Win2000 server Security Configuration, a carefully configured Win2000 server can protect against more than 90% intrusion and infiltration, but system security is a continuous process, with the advent of new vulnerabilities and server application changes, the security situation of the system is also changing At the same time, because of the contradictory unity of

. 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

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
