Protocols such as Transport Layer Security (TLS) and Hypertext Transfer Protocol Secure (HTTPS) protect patient data in ____, whereas encryption of stored files protects data at rest.

### Why this is right The listed secure channels protect patient information while it is being transmitted between systems. The material distinguishes this from encryption of data at rest, which protects stored information. ### The concept Data in transmission is moving across a connection and could be intercepted if the channel is not protected. Encryption during transmission helps make intercepted data unreadable to unauthorized parties. Encryption at rest protects stored data, such as information on a device or in storage. Key management is needed because authorized users must be able to use the keys that protect encrypted information, while unauthorized users should not. ### Terms - **Transport Layer Security (TLS)**: a protocol used to protect data sent over a network connection. - **Hypertext Transfer Protocol Secure (HTTPS)**: a secure form of web communication that uses encryption. - **Virtual private network (VPN)**: a protected network connection used to carry data between endpoints. - **Data at rest**: information stored on a device or system. ### Remember Encryption at rest protects stored information; secure channels protect information in transit.
