Web filtering for education using AWS Network Firewall with egress TLS inspection

This article discusses using AWS Network Firewall with TLS inspection for web filtering in educational environments, demonstrating how to decrypt and inspect encrypted HTTPS traffic.

• Enables visibility into encrypted traffic, even with Encrypted Client Hello (ECH)
• Decrypts and re-encrypts HTTPS traffic to inspect encrypted data
• Uses a self-signed certificate for TLS inspection (not recommended for production)
• Implements Suricata-based rule groups to filter web traffic
• Provides step-by-step guide for deploying Network Firewall with TLS inspection

The solution allows organizations to effectively filter HTTPS traffic, enforce URL-based access control, and improve network security by inspecting encrypted communications.
