Which term refers to preventing mass data exfiltration using an external device?

• A. Print blocking
• B. RDP Blocking
• C. VDI Implementation Restriction
• D. Removable/External Media Blocking

Answer: (D)

Blocking removable and external media focuses on preventing data from being copied to USB drives, external hard drives, and other portable storage. This directly stops mass exfiltration by making it difficult or impossible to physically carry large amounts of data out of the organization on a device. Implementations often use endpoint security or policy controls to disable, restrict, or monitor access to removable storage, and they log events for incident response.

Other vectors aren’t the primary target here: printing blocks hard copies, which is a different leakage path; blocking remote desktop protocols stops remote access that could be used for exfiltration over a network; and restricting virtual desktop infrastructure reduces certain deployment risks but doesn’t address the specific risk of taking data out on removable media.
