Gabriel wants to make certain that sensitive data can be transmitted in unencrypted form by using physical safeguards. What type of solution should she implement?

Protected cable distribution uses such controls as electrical, electromagnetic, and even acoustic or air pressure sensors to ensure that cables and distribution infrastructure are not accessed, allowing sensitive information to be transmitted in unencrypted form. The U.S. government identifies three options: hardened carrier, alarmed carrier, and continuously viewed protected distribution systems. Shielded cables are used to prevent EMI.
