Endpoint-Based DLP systems are responsible for which of the following?

Endpoint-Based DLP (Data Loss Prevention) systems are designed specifically to monitor and protect sensitive data that resides on endpoint devices, such as laptops, desktops, and mobile devices. The primary function of these systems is to scan files and monitor activities on these endpoints to prevent unauthorized access and sharing of confidential information. This includes checking documents and files for sensitive data patterns, enforcing security policies, and blocking actions that could lead to data breaches, such as copying data to external drives or sending it through unsecured channels.

While the other options may relate to DLP and data protection in general, they do not accurately describe the specific role of endpoint-based DLP systems. For instance, preventing data transfer on the network pertains more to network-based DLP solutions, while monitoring network traffic typically involves tools dedicated to observing data flows rather than focusing on endpoint activity. Storing data on cloud services is outside the scope of what an endpoint-based DLP system does, as its main focus is on monitoring and controlling data at the specific device level. Therefore, scanning files on endpoint devices is indeed the correct identification of the fundamental responsibility of endpoint-based DLP systems.
