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 security personnel to detect massive network info

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. Today we talk about how to query suspicious connection, call Task Manager Ctrl+shift+esc key combination, find the corresponding PID value, r

Generally, when enterprises or organizations are preparing to enter this field, they often choose to start with network-based IDS, because there are a lot of open source code and materials on the Internet, which is easier to implement, in addition, network-based IDS have strong adaptability. With the development experience of simple network IDs, it is much easier to move towards host-based IDS, distributed IDs, and intelligent IDs. Here, I will take network-based IDS as an example to introduce t

Linux Kernel security is gaining more and more attention with the popularity of Linux systems. Here we will introduce LIDS, the Linux kernel security intrusion detection system. Check what problems exist in the Linux kernel and what features LIDS can bring to us. LIDS (Linux Intrusion Detection System) is a Linux kerne

Implanted attack intrusion detection Solution1. What is an implant attack? What is an implant attack? In other words, Trojan horses are used to upload Trojans to your system, modify the original programs, or disguise programs. It is hard for you to find out, and resident systems.2. Why do hackers implant Trojans in your system? In general, Trojan attacks target hackers and seldom damage your system. Instead

[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

Suricata is a network intrusion detection and protection engine developed by the Open Information Security Foundation and its supported vendors. The engine is multi-threaded and has built-in support for IPv6. You can load existing snort rules and signatures, Support for Barnyard and barnyard2 tools Suricata 1.0 improvements: 1. Added support for tag keywords;2. DCERPC supporting UDP;3. Duplicate signature

Intrusion detection and network audit product is the twin brother? Intrusion detection System (IDS) is an important tool for network security monitoring, is the network "Street" on the patrol, always pay attention to the abnormal behavior of the network, network audit is the user's behavior record, is the network "

As an excellent open-source host intrusion detection system, Snort can be installed and run on both windows and Linux platforms. As a Linux operating system based on desktop applications, Ubuntu can also install Snort. During the Snort installation process, [install LAMP, Snort and some software libraries] Ubuntu is a Debian Linux system, which is very simple to install software and Ubuntu has images at the

Currently, application-level intrusion into applications and their background databases has become increasingly rampant, such as SQL injection, cross-site scripting attacks, and unauthorized user access. All these intrusions may bypass the front-end security system and initiate attacks against data sources. To deal with such threats, the new level of security stands out, which is application security. This security technology applies the traditional n
