Role-Based Access: Restrict user access based on roles and permissions. 4. SSL/TLS Encryption: Secure Sockets Layer (SSL) and Transport Layer Security (TLS): Use SSL/TLS certificates to encrypt data in transit. HTTPS: Enable HTTPS for your website to ensure secure communication. 5. Web Application Firewall (WAF): WAF Deployment: Deploy a WAF to filter and block malicious traffic. Signature-Based and Behavior-Based Rules: Configure WAF rules to identify and thwart attacks. 6.
