Explanation
Strong data loss prevention (DLP) solutions help protect information in all states: at rest, in transit and in use.
This is because DLP solutions are technologies or tools that help to prevent unauthorized or accidental disclosure, modification, or deletion of sensitive or confidential information by users or applications. DLP solutions help to protect information in all states, by applying different types of controls or mechanisms depending on the state of the information. For example, DLP solutions can protect information at rest by encrypting or masking the data stored on devices or media; protect information in transit by inspecting or filtering the data transmitted over networks or channels; and protect information in use by restricting or monitoring the access or usage of the data by users or applications. The other options are not states that strong data loss prevention (DLP) solutions help protect information in, but rather different levels (B), classifications C, or actions (D) that are related to information security.
