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 question and answer form, which is expected to help

Article Title: the IDS intrusion detection tool in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. This article briefly introduces several Linux IDS intrusion detection tools

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 technology that detects, records, alerts, and responses. It not only detects external intrusions,

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 there are violations of security policies an

This article briefly introduces several Linux IDS intrusion detection tools, such as psad, Apparmor, and SELinuxu. First, let's take a look at the principles and practices of the intrusion detection system. If you only have one computer, it is entirely possible for you to spend a lot of time carefully reviewing system

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 mode simply reads the packet from the network and displays it as a continuous stream on the

Linux Kernel real-time Intrusion Detection security enhancement-introduction-general Linux technology-Linux programming and kernel information. The following is a detailed description. I. Introduction Ice cubes It is now recognized that there is no absolute method or absolutely secure system in the world to prevent hacker intrusion: Software without vulnerabilit

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 intrusion detection system is different from the firewall in that the firewall

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-System Platform operations, it has the least impac

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 contradictions, the Director and the Director are constantly changing. Therefore, a brilliant syste

Security O M: Use of Linux backdoor intrusion detection tools 1. Introduction to rootkit Rootkit is the most common backdoor tool in Linux. It mainly replaces system files for intrusion and concealment. This Trojan is more dangerous and concealed than a common backdoor, it is difficult to find such Trojans through common det
