What are the security protection measures for CDN servers?Security protection measures include preventing DDoS attacks, deploying WAF, using SSL/TLS protocol encryption, access control, security audit logs, strengthened authentication and authorization, regular security updates and patches, security scanning and vulnerability assessment, security training and awareness, network isolation and Security configuration, etc. Detailed introduction: 1.

How to prevent DDoS attacks after nginx reverse proxyMethods to prevent DDoS attacks: You can limit the number of requests per second. Use the ngx_http_limit_req_module module to limit the number of requests per unit time through the leaky bucket principle. Once the number of requests per unit time exceeds the limit, a 503 error will be returned; then you can also limit IP connections. number to prevent attacks.
