Episode 101 — TLS Inspection: what it reveals, what it breaks, performance impact
TLS inspection appears in CloudNetX scenarios as a deliberate tradeoff between visibility and privacy, and the exam expects you to understand both the security value and the operational risk. This episode defines TLS inspection as decrypting encrypted traffic at a controlled point, inspecting content for policy enforcement or threat detection, then re-encrypting traffic for delivery to its destination. The first paragraph focuses on what TLS inspection reveals: malicious payloads hidden in encrypted sessions, policy violations such as disallowed uploads, and sensitive data movement that would otherwise be invisible to network controls. It also explains why inspection is sometimes required by policy or compliance, especially when the organization must demonstrate that sensitive data is not leaving through encrypted channels. The episode frames inspection as an architectural control that must be scoped intentionally, because inspecting everything is rarely feasible or appropriate.
