Network security defense system based on dynamic transformation

Abstract

The invention belongs to the technical field of network security, and particularly relates to a network security defense system based on dynamic transformation, which comprises an independent antivirus terminal, a network monitoring terminal, an external equipment monitoring terminal, a data backup unit and a dynamic transformation unit. The independent antivirus terminal is used for carrying outvirus searching and killing on at least one network terminal. The network monitoring terminal is used for detecting the security of data transmission of the network terminal. The external equipment monitoring terminal is used for detecting whether the external memory carries viruses or not. The data backup unit is used for backing up important information in the network terminal when the network terminal is attacked by viruses. The dynamic conversion unit is used for generating a virtual IP address according to the real IP address of the network terminal and connecting the network through thevirtual IP address. Compared with the prior art, the operation speed of the network terminal can be remarkably increased, meanwhile, network security protection with a high security coefficient is achieved, and the security of the network terminal is improved.

Description

technical field [0001] The invention belongs to the technical field of network security, in particular to a network security defense system based on dynamic transformation. Background technique [0002] In the 21st century, with the advent of the Internet information age, the price of personal computers in China is getting lower and lower, and the cost of accessing the Internet is also getting lower and lower. When computer users visit websites through browsing, they often have network problems. Chinese computer users generally have low computer skills, especially when opening a webpage and clicking on some online reading websites or video websites, the repeated advertisement pop-up windows and newly opened browser pop-up windows make computer users miserable . Pop-up windows and some virus and Trojan horses will be downloaded secretly and will continue to cause system memory loss, and eventually the system will crash and freeze. [0003] The most common network security d...

Pop-up windows and some viruses and Trojan horses will be downloaded secretly and will continue to cause system memory loss, and eventually the system will crash and freeze

[0003] The most common network security defense scheme in the existing technology can only passively defend and will not actively restore the computer's memory to make the system smooth. On the contrary, the common network security defense system still keeps occupying the system's memory, making the system It becomes very stuck, which affects the performance of the computer, causing many new personal computers to be unwilling to install a network defense system
