Definition: A security process that encodes data to prevent unauthorized access.
Explanation
Encryption is the process of converting data into a coded format that can only be accessed or read by someone who has the correct decryption key or password. It protects data from unauthorized access, especially when devices or files are lost or stolen. However, once the authorized user decrypts the data, encryption no longer controls how the content is used or shared.
Example
If a USB drive containing sensitive documents is encrypted, anyone who finds the drive cannot open the files without the password. But once the intended recipient enters the password and accesses the files, they can copy, share, or modify the content unless additional controls are in place.
Who This Is For
This term is important for IT professionals, content creators, business owners, and anyone responsible for protecting sensitive digital files from unauthorized access or theft.
