snort intrusion detection system

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

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

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

The progress of this project is still unknown, and the FAQ author cannot obtain known data.The general Intrusion Detection Framework (CID

[citation]: The role of intrusion detection is to monitor intrusion events, to protect important data from illegal theft.your data is stored in RAM, but the data in a power-down RAM is gone;there is a place where the data of a piece of RAM related to the backup battery is not released (unless the battery is dead);There is also a way to automatically clear out thi

Intrusion detection is considered to be the second security gate behind the firewall, which can monitor the network effectively without affecting the network performance. However, for a long time, the problem of "false report" and "false positives" of IDs has been bothering users. In this respect, the East soft Neteye IDs from "Application First", in the full range of products strictly implement this idea,

With the rapid development of networks, networks have become an indispensable part of computer applications. However, the risks and opportunities of network attacks also increase rapidly. How to establish a reasonable network security system has become a hot issue in the network field. Currently, it is impossible for developers to ensure that the development software does not have any vulnerabilities, at the same time, it is difficult for network secu

It does not have interoperability issues and provides customers with more aggressive defense capabilities, including mixed threats, by integrating Symantec's long-standing reputation for antivirus,

Introduction This article focuses on several host-based Intrusion Detection Systems on Linux. In addition, I will introduce how to install these software packages, how they are useful, and when they are used. System Security 101 This article assumes that you have some basic knowledge about system security. In addition,

The netstat command can help us understand the overall usage of the network. Depending on the netstat parameters, it can display different network connection information. Netstat parameters, some of which are described below. How to detect whether there is a Trojan horse, the computer system backstage has been secretly manipulated, whether to be monitored.
