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
Intrusion DetectionThe system is not omnipotent, and the high price also makes people retreat. Moreover, the investment in configuring intrusion detection systems or firewalls for a single server or small network is too large. In previous articles, we have introduced part of the process of Windows2000 Server intrusion
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.

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

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

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
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

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 can we discover intrusions? The following describes some common check methods.

Since computers are connected through networks, network security has become a major problem. With the development of the INTERNET, security system requirements are also increasing. One of its requirements is intrusion detection systems.This article aims to introduce several common Intrusion Detection Systems and Their

Are there any open standards for intrusion detection?
So far, there are no mature open standards for intrusion detection. But we are working in this direction.An Internet Engineering Task Group (IETF) is an entity that develops Internet standards. They have a working group dedicated to developing a common IDS alarm for
