What should a company do to best protect itself from data exfiltration via removable media?

Utilizing host-based security tools to block removable-media devices is an effective strategy for preventing data exfiltration. Removable media, such as USB drives, can easily transport significant amounts of data out of an organization, posing a considerable risk if misused. By implementing security controls that directly restrict or control the use of these devices, a company reduces the chances of sensitive or proprietary data being transferred outside the organization without authorization.

This proactive approach ensures that even if malicious actors attempt to use removable media for data theft, they will be thwarted by the security measures in place. This method is also advantageous because it can be implemented across all endpoints and managed centrally, ensuring consistency and compliance with security policies.

Other strategies, such as monitoring large data transfer transactions or providing training on the media policy, can complement this measure but do not provide the same level of immediate and direct protection against the physical transfer of data via removable devices. Group policies to block user access may also be effective; however, the application of host-based security tools specifically addresses the core issue of removable media access and usage.
