Episode 19 — Encrypt data in transit across every open pathway

Data in transit crosses many boundaries—wired, wireless, internal, and external—and the exam expects you to secure each with protocols and configurations that stand up to scrutiny. This episode clarifies what “strong” means in practice: current, secure versions of TLS with certificate validation, robust cipher suites, and verified configurations on both client and server components. We address internal traffic as well as public connections, including administrative sessions, application-to-database links, APIs to providers, and user endpoints. You will learn to spot weak patterns in stems such as accepting self-signed certificates in production paths, leaving older protocol versions enabled for “compatibility,” or using plaintext protocols for device management. We connect controls to artifacts like configuration exports, certificate inventories with expiration tracking, and automated test outputs that prove secure negotiation.Examples show common pitfalls and exam-ready remedies. A reverse proxy terminates TLS but forwards clear-text to an application tier that shares a network with untrusted systems; the correct answer extends encryption or enforces segmentation that compensates adequately. A mobile app pins certificates but the back-end API rotates keys without process alignment, causing insecure fallbacks; the right choice maintains strong validation with planned rotations and monitoring. Wireless traffic on a guest network uses modern encryption yet bridges to internal networks through shared services; the exam will favor isolation and controlled routing that preserves boundaries even when radio encryption is sound. Troubleshooting includes handling legacy agents, securing file transfers used by vendors, and validating that monitoring tools can decrypt or inspect traffic where policy allows, or else rely on metadata and endpoint telemetry for coverage. Select answers that close every live path with strong protocols and that produce evidence of configuration, testing, and lifecycle management.
