Exploring HTTP/HTTPS Security Through Controlled Downgrade Attack Simulations
ShadowSentinel is a hands-on exploration of HTTP and HTTPS communication through controlled security experiments conducted in an isolated virtual environment.
The project explores how protocol downgrade scenarios can occur under insecure configurations and examines how modern web security mechanisms—including HSTS, TLS certificate validation, and browser security policies—help defend against them.
Rather than claiming to "break HTTPS," ShadowSentinel focuses on understanding protocol behavior, experimenting with real-world security concepts, and learning how modern browsers and transport-layer protections mitigate downgrade attacks in authorized environments.
