Research and application of Web network attack protection and block chain log storage based on software definition

At present, the network space environment is complex, and the network attack protection is easy to conflict with the normal business. Aiming at this problem, this paper proposes a Web network attack protection system based on the software definition architecture, which uses the detection module injection and honeypot technology, and realizes a network attack protection method based on the storage of block chain. This method can effectively reduce the pressure on the production server and confuse the attacker to achieve the effect of environmental attack. In addition, it can also combine with the blockchain to quickly store the evidence of attack.
