The network security risks faced by foreign trade websites far exceed those of domestic trade websites. They not only have conventional SQL injection and XSS attacks, but also need to deal with targeted threats such as cross-border DDoS attacks and data theft. It is urgent to build a comprehensive protection system. The protection system should be built from three levels: network layer, application layer, and data layer, forming a defense in depth.

The core of network layer protection is the deployment of advanced anti DDoS CDN and WAF (Web Application Firewall). Advanced anti DDoS CDN can hide the source server IP and disperse DDoS attack traffic, while WAF can accurately identify and intercept malicious requests such as SQL injection and XSS, and update protection rules for different attack characteristics in different regions. The application layer needs to strengthen code security by using methods such as parameter filtering and input validation to avoid vulnerabilities, conducting regular code audits and penetration testing, and promptly fixing security risks.

The focus of data layer protection is to ensure the security of user information and transaction data. Sensitive data needs to be encrypted and stored, and HTTPS protocol is used to achieve data transmission encryption. At the same time, strict compliance with data compliance requirements of target markets such as GDPR and CCPA is required. In addition, it is necessary to establish a security monitoring and emergency response mechanism, detect abnormal access behavior in a timely manner through a real-time monitoring system, develop emergency response procedures for attacks, and minimize the losses caused by attacks. Security protection is not a one-time solution, and protection strategies need to be continuously upgraded based on the development of network attack technology.
