Encryption at Rest
Encryption
Scrambling data while it’s stored.
Definition
Encryption at rest protects data saved on a device or server (disk, database, backups) so it can’t be read without the right key.
In plain English
Scrambling data while it’s stored.
Why this matters
Why it matters: If a laptop is stolen or a server is accessed, encrypted data is harder to misuse.
Example
Example: Your phone storage is encrypted with your passcode.
