Security - Process
Encryption at rest
Protecting stored data by scrambling it so it cannot be read without the right key
What's it for?
Protects stored information so someone who gets the files or disks still cannot easily read it.
For example…
Stored files remain unreadable without the correct key
A company encrypts its stored customer records so that someone who steals a copy of the underlying files cannot read the information
Think of it like…
Keeping papers in a locked filing cabinet when the office is closed
