Which of the following best describes data loss prevention?

Data loss prevention (DLP) is best described as a system for keeping sensitive information safe from unauthorized access or leaks. This encompasses various strategies and tools designed to monitor and control the transfer of sensitive data, ensuring that sensitive information does not leave the organization unintentionally or maliciously. DLP solutions typically include methods for identifying, monitoring, and protecting sensitive data at rest, in motion, and in use. By implementing DLP, organizations can help mitigate risks associated with data breaches and maintain compliance with various regulations regarding data privacy and security.

The context surrounding other options highlights their different focuses. Procedures for recovering lost digital files relate to data recovery rather than preventing data from being lost or exposed originally. Securing physical storage devices is more about physical security measures and does not directly address the handling and protection of sensitive information. Tools for reporting data misuse are responses to data breaches or misuse rather than proactive measures to prevent loss or leaks of data in the first place.
