Episode 34 — Operate encryption keys under strict dual control
This episode covers dual control for cryptographic keys and why the ISA exam treats it as more than a procedural formality, especially when keys protect account data or enable decryption in sensitive systems. You’ll define dual control and split knowledge, then explain how they reduce insider risk by ensuring no single person can unilaterally generate, activate, export, or use critical keys without oversight. We’ll walk through how dual control is implemented in modern environments, including HSM-backed key management, cloud KMS workflows, and controlled key ceremonies, and we’ll connect those mechanisms to the evidence an assessor expects. You’ll learn how to evaluate real enforcement by checking role assignments, approval workflows, audit logs, and technical constraints that prevent a single administrator from bypassing controls. Troubleshooting scenarios will include small teams where duties overlap, emergency access requests, and legacy platforms that lack strong separation, along with practical design options such as compensating workflows, controlled break-glass access with logging, and governance that keeps the control defensible under operational pressure.
