It brings the convenience of connection and service. The rapid development of WEB technology not only improves people’s ability to acquire and manipulate information, but also produces more serious security problems. In view of this, this paper combines firewall technology and intrusion detection technology to enhance the ability of honeypot technology (HT) to deceive attackers, and designs a WEB security protection system based on HT. The system can guarantee the reliability of the web in the face of web attacks, and can restore text files and data in time. After testing the performance of HT, it is proved that HT can improve the speed of WEB application to open web pages.
