I. AIDE Introduction AIDE (Adevanced Intrusion Detection Environment, Advanced Intrusion Detection Environment) is an Intrusion Detection tool used to check the integrity of documents. AIDE can construct a database for a specified

processes from being terminated illegally. However, when the intruder has the ROOT permission, we cannot do anything. System Management unprotected Many system management systems, such as module loading/uninstallation, route setting, and firewall rules, can be easily modified if the user ID is 0. Therefore, it becomes insecure when intruders obtain the ROOT permission. Super User (root) as ROOT may abuse p

Article Title: about the use of Linux kernel security intrusion detection system. 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 section briefly introduces the Linux kernel se

is changed for a legitimate reason. For some customers, their security policies may require some Intrusion Detection System (IDS) to be installed on the server ). However, whether users require IDS or not, system administrators can deploy IDS. Install AIDE on CentOS or RHEL The initial installation (and first running)

Therefore, it becomes insecure when intruders obtain the ROOT permission. Super User (root) as ROOT may abuse Permissions He can do whatever he wants. as ROOT, he can even modify the

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 gua

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

This section briefly introduces the Linux kernel security intrusion detection system and introduces the problems exposed by the Linux System and the features of the intrusion detection system
