CompTIA Security+ Question D-21

Several employees have been printing files that include personally identifiable information of customers. Auditors have raised concerns about the destruction of these hard copies after they are created, and management has decided the best way to address this concern is by preventing these files from being printed.
Which of the following would be the BEST control to implement?

A. File encryption
B. Printer hardening
C. Clean desk policies
D. Data loss prevention

Answer: D

Explanation:
Data loss prevention (DLP) systems monitor the contents of systems (workstations, servers, and networks) to make sure that key content is not deleted or removed. They also monitor who is using the data (looking for unauthorized access) and transmitting the data. This would address the concerns of the auditors.
