Episode 4 — Select Symmetric Encryption Algorithms Based on Speed, Use Case, and Risk
This episode focuses on symmetric encryption choices and the decision logic behind using fast shared-key cryptography for protecting data at rest and data in motion, a foundational topic that appears throughout secure system design and operational controls. You will learn where symmetric encryption is the right tool, how to think about algorithm strength versus configuration, and why operational practices like key storage and access control frequently determine real security outcomes. We cover common use cases such as encrypting backups, disks, databases, and service-to-service traffic, then discuss tradeoffs involving performance, compatibility, and risk exposure when legacy protocols or weak modes are still present. Along the way, you will hear troubleshooting considerations for verifying encryption is actually enabled, spotting insecure defaults, and planning for key rotation when data lifetimes exceed key lifetimes.
