Microsoft Defender for Endpoint has new options to secure removable storage on Windows and macOS. Microsoft also has new printer protection capabilities in preview through the software (via Bleeping Computer). The new options should help organizations secure PCs that use external devices.

Microsoft explains that with more people working from home, devices like printers and removable storage have become targets for attackers:

External devices such as USB and home printers are commonplace tools needed to complete daily business operations. These devices help employee productivity, but also pose a threat to enterprise data and serve as a potential entry point for malware and viruses. The move to remote work due to COVID-19 over the last year has raised the risk to another level.

Microsoft Defender for Endpoint already has control protections for device installation, removable storage Endpoint DLP, and removable storage BitLocker. Now, the program also has control capabilities for removable storage access on Windows.

Microsoft explains that "the new feature allows to Audit/Allow/Prevent Read, Write, or Execute access to removable storage based on various device properties, e.g., Vendor ID, Serial Number, Friendly Name, with or without an exclusion."
