Why it matters: Exploiting USB devices and the protocol itself has become far too easy in recent years. Widespread availability of inexpensive malicious hardware has lead many to simply disable unused ports. Through the addition of cryptographic authentication to USB Type-C devices, a much greater level of protection is offered.
System administrators have had to take additional precautions over the past several years in order to avoid abuse of USB ports on devices. Today, the USB Implementers Forum has officially launched the USB Type-C Authentication Program that sets standards for improved security.
