Data is constantly on the move—or waiting to be accessed—and must be protected in both states. In this episode, we examine the best practices for securing data at rest (stored on disk or cloud) and data in transit (moving across networks). You'll learn about encryption methods, key management practices, access controls, and monitoring techniques. We also address compliance requirements that demand specific protections for data in these states. Protecting data wherever it resides or flows is a foundational concept every CISSP candidate must master.
