A cybersecurity analyst is reviewing the data lifecycle within their organization's financial systems. The analyst is focusing on securing sensitive data, such as credit card numbers and transaction details, at the moment it is being actively processed by an application in the system's RAM and CPU. Which data state is the analyst currently examining?
The correct answer is 'Data in use'. Data in use refers to information that is actively being processed or manipulated by an application, which includes being loaded into system memory (RAM) or processed by the CPU. 'Data at rest' describes data that is stored on a physical medium like a hard drive or database and is not currently being accessed. 'Data in transit' refers to data that is moving across a network. 'Encrypted data' is not a data state itself but a security control that can be applied to data in any of the three states (at rest, in transit, or in use).
