Abstract

The present disclosure relates to a method, device, storage medium, and equipment for preventing network attacks, and relates to the field of communication technology. The method includes: when a first data packet is received, according to the The source IP address obtains the information entropy of the source IP address of the data flow, determines whether there is a denial of service DoS attack according to the information entropy, and when there is a DoS attack, carries out defensive processing on the first data packet through the size of the information entropy. It can reduce the impact of the defense mechanism on the TCP protocol and reduce the consumption of system resources.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a method, device, storage medium and equipment for preventing network attacks. Background technique [0002] With the rapid development of information technology such as the Internet, people's lifestyles and habits have also undergone tremendous changes. At every moment, there will be massive data in the Internet for communication and to provide services for people's various activities. Therefore, Network security issues are extremely important in today's communication technology field. Among the various attack methods on the Internet, DoS (English: Denial of Service, Chinese: Denial of Service) is the most widely applicable TCP / IP protocol (English: Transmission Control Protocol / Internet Protocol, Chinese: Transmission Control Protocol / Internet Protocol). ) attack is the most serious. [0003] In the DoS attack, the most important method is SYN (English: S...
