In an era of increasing digital threats, implementing security headers such as HSTS and CSP is crucial for safeguarding web applications and their users. This guide provides technical and practical instructions for deploying HSTS and CSP at the edge using Azion Applications, highlighting the advantages of such an approach, including reduced latency and enhanced security through instant deployments and continuous protection. HSTS, or Strict-Transport-Security, ensures browsers use HTTPS, protecting against downgrade and MITM attacks, while CSP, or Content-Security-Policy, mitigates XSS attacks by defining trusted sources for web resources. The article outlines step-by-step instructions for configuring these security measures using Azion's Rules Engine, emphasizing best practices like starting with report-only mode for CSP and gradually enforcing policies. By applying these headers at the edge, organizations can reduce latency, block malicious traffic early, and improve compliance with regulatory requirements such as LGPD and HIPAA, ultimately enhancing the security and performance of their web applications.
