Layer 7 Network Policies

This hands-on lab guides you through implementing Layer 7 (application layer) network policies with Cilium.

You'll learn to:

• Deploy an HTTP-based application for L7 policy testing
• Create policies that filter based on HTTP paths
• Implement HTTP method restrictions (GET, POST, etc.)
• Use Hubble to observe L7 traffic flows
• Understand the performance implications of L7 policies

Layer 7 policies provide fine-grained control over application traffic and are a key differentiator of Cilium.

Key Resources:

• L7 Protocol Visibility
• HTTP-Aware Policy
