Which cybersecurity architecture layer protects enterprise data whether it is at rest, in motion, or in use?

### Why this is right Data security is defined by what it protects: enterprise data in any state. It therefore applies whether information is stored, transferred, or being used. ### The concept Architecture layers protect different parts of an enterprise. Perimeter security helps guard back-end systems from remote activity, network security partitions connections, and endpoint security protects devices. Data security follows the information across those settings rather than protecting only one device or network boundary. ### The other options - **Perimeter security**: protects against remote malicious activity and unauthorized access to back-end systems. - **Network security**: partitions a broader network into groups. - **Endpoint security**: protects devices that connect to networks or systems. ### Terms - **Perimeter security**: physical and technical measures, plus policies, that help protect systems at the enterprise boundary. - **Endpoint**: a device such as a computer, laptop, phone, or tablet. - **Data at rest, in motion, and in use**: data that is stored, transferred, or actively processed. ### Remember Data security follows the data, while endpoint and network security focus on particular parts of the environment.
