Episode 40 — Select transport protocols that protect privacy across modern and legacy paths (Domain 4B-4 Communication and Transport Protocols)

This episode focuses on communication and transport protocols as privacy safeguards, because the protocol choices and configurations determine whether data can be intercepted, altered, misrouted, or exposed through weak defaults. You’ll learn how to evaluate protocols in terms of confidentiality, integrity, authentication, and downgrade risk, and how to recognize when “encrypted somewhere” is not the same as end-to-end protection with clear trust boundaries. We’ll work through scenarios involving web traffic, API calls, file transfers, email-like workflows, legacy integrations, and internal service traffic, highlighting where privacy risk increases with plaintext channels, weak certificate handling, or inconsistent enforcement across environments. You’ll also practice choosing best practices that are exam-relevant, such as strong encryption in transit, modern protocol configurations, mutual authentication where appropriate, and monitoring that can prove secure transport is actually being used.
