Definition
Device Encryption is a data-protection mechanism that transforms stored data into a form unreadable to anyone without the appropriate authorisation or cryptographic keys.
Human Explanation
Even if a device is lost or stolen, the data stored on it remains inaccessible without the correct means of decryption.
Why it Matters
Encryption reduces the Risk of information disclosure when a device is lost or its storage is accessed without authorisation.
Conceptual Boundary
Device Encryption protects stored data, but it does not secure a device against every type of attack or replace other security mechanisms.
Practical Perspective
Device Encryption creates the greatest value when it is the standard for every device that stores organisational data.
