Lockheed Martin and IronKey have teamed up to create a new, ultra-secure USB drive called IronClad. The boot drive contains an operating system, programs and files, allowing users to plug it into any host PC and have access to their own desktop and files. There is no real need to access the host computer's hard drive, and the IronClad USB drive has 256-bit hardware-level encryption for protection from malware threats, including with rootkits.
