Episode 63 — Web Communication Security II: Headers and HSTS
The smallest details in web configuration often have the biggest impact on security, and this episode explains how HTTP headers and strict transport policies shape browser behavior. You’ll learn about critical headers like Content-Security-Policy (CSP), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy, all of which defend against common injection and clickjacking attacks. The discussion explores how browsers interpret these directives, translating simple configuration lines into robust front-line protections.
Listeners will also learn how HTTP Strict Transport Security (HSTS) enforces encrypted connections, eliminating the risk of downgrade attacks or accidental plaintext exposure. The episode walks through how to enable, test, and validate these headers safely, as well as how to use tools like security scanners to identify missing or misconfigured directives. By understanding how these small configurations add up to significant hardening, you’ll be able to answer exam questions confidently and improve the real-world resilience of any web platform.
