snort intrusion detection system

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

The firewall has two main limitations:1, the firewall is Access control equipment (ACL), mainly based on the source IP address to real access control, to achieve the security of the network layer, but can not detect or intercept the injection in ordinary traffic malicious attack code, such as the Web service injection attacks.2. The firewall is unable to detect or intercept attacks that occur in the internal network.Firewall is the first line of defense to achieve network security,

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

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

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
