ISC2 CISSP Practice Question

An organization operates a classified research network that is air-gapped from the Internet. Engineers occasionally request to connect USB flash drives to transfer configuration files. Which of the following is the BEST control to mitigate the security risks posed by portable USB storage devices in this highly sensitive environment?

  • Permit engineers to use personal USB drives after they sign an acceptable-use agreement acknowledging the risks.

  • Require users to run an antivirus scan on their USB drive and lift all restrictions if no malware is detected.

  • Implement USB port control that blocks all unauthorized devices and allow only organization-supplied, encrypted, whitelisted drives under a formal approval process.

  • Allow any USB device to be connected as long as endpoint antivirus and EDR software are kept up to date.
