intrusion detection system tutorial

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

applied data and is not included in the TCP/UDP/IP header. To achieve a higher level of security, the firewall must combine the packet filter and the application gateway. An application gateway, which is an application-specific server in which all application data must pass through the application gateway. Multiple application gateways can run on the same host, but each gateway is a separate server with its own process. However, the application gateway also has its drawbacks. First, each applic

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

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

The Intranet Intrusion detection system ("IDs system") can find out some high risk events such as network virus, system vulnerability, abnormal attack and so on in time, which enhances the security of intranet, and effectively guarantees the normal operation of each importan
