Static encryption refers to protecting data at rest, while dynamic encryption refers to protecting data in transit.

### Why this is right The lesson uses static encryption for data at rest, such as whole disks or individual files. It uses dynamic encryption for data moving across a network, with examples including virtual private networks and Transport Layer Security. ### The concept At-rest protection applies while information is stored. In-transit protection applies while information travels between systems. These describe where or when the protection is applied, not whether the method is symmetric or asymmetric. A system may use more than one cryptographic method in either setting. ### The other options - **False. Static encryption refers to protecting data at rest, while dynamic encryption refers to protecting data in transit.**: This reverses the lesson’s stated definitions. ### Terms - **Data at rest**: Stored data that is not currently moving between systems. - **Data in transit**: Data being sent across a network or communication link. - **Virtual Private Network (VPN)**: A protected network connection used to secure communications. - **Transport Layer Security (TLS)**: A protocol used to protect network communications. ### Remember Static means stored; dynamic means moving.
