Episode 23: Information Lifecycle and Data Classification

Understanding how data flows through its lifecycle is essential for protecting it appropriately. This episode walks through the phases of the information lifecycle: creation, storage, usage, transmission, archival, and disposal. We then examine data classification schemes—such as public, internal, confidential, and restricted—and how classification drives the application of controls. You'll learn how to create classification policies, apply labels, and ensure data is treated consistently according to its value and sensitivity. This foundation is critical for managing risk and enforcing security policies across diverse data environments.
