The development and adoption of removable USB mass storage is truly remarkable. On the other hand, most security officers wish that this technology didn’t exist at all. First of all it is a medium that can carry computer viruses and software that shouldn’t be used in the corporate environment. To deal with this issue, some organizations have disabled USB ports through the BIOS, while others have gone to the more extreme measure of filling the USB connectors with a thick epoxy adhesive. Surprisingly, there are very compelling advances to be gained in the security industry by properly harnessing the power and protocol of USB mass storage. As any technology evolves we always see more features and functionality being added to newer models of devices. Some flash drives even have fingerprint sensors and processors built in so that biometric authentication of the owner is required before the storage can be accessed.
