Episode 56: Encryption Principles and Practices

Encryption is a cornerstone of data protection, and in this episode, we break down its role in securing data both at rest and in transit. You’ll learn about the key encryption types—symmetric, asymmetric, and hashing—and how each serves a distinct purpose in confidentiality, integrity, and authentication strategies. We explore how encryption is applied across systems, from full-disk encryption and encrypted databases to TLS protocols, encrypted backups, and secure communications. From a CCISO perspective, implementing encryption isn’t just about deploying the right algorithm—it’s about key management, policy alignment, regulatory compliance, and ensuring usability doesn’t suffer in the process. We also discuss hardware security modules (HSMs), cloud key management systems, and emerging topics like homomorphic encryption and post-quantum cryptography. On the exam, you’ll need to demonstrate both conceptual understanding and executive oversight of encryption strategies across your enterprise.  Ready to start your journey with confidence?
