Episode 43 — Protect Data in Transit Using TLS Choices and Certificate Hygiene
This episode explains how to protect data in transit using TLS and disciplined certificate management, a topic that appears on the exam through encryption, identity assurance, and operational troubleshooting scenarios. You will learn what TLS provides, including confidentiality and endpoint verification, and how to decide where encryption must be enforced end-to-end rather than relied on “somewhere in the middle.” We cover certificate lifecycle management, including issuance, renewal, revocation, monitoring, and ownership, and why expired certificates commonly trigger outages and unsafe workarounds that weaken security. A scenario explores a partner integration under time pressure where someone proposes disabling verification, and you will learn how to maintain trust while restoring functionality by fixing trust chains, renewals, and configuration errors. Troubleshooting considerations include weak protocol support, inconsistent configurations across services, failure to automate renewal, and lack of visibility into certificate sprawl, all framed as governance problems leaders can solve with standards, inventory, and measurable controls.
