“We have significantly reduced the ‘surface’ that can be attacked by malicious software,” says Dr. Peng Ning, a professor of computer science at NC State and co-author of a paper describing the research. “For example, our approach relies on a software foundation called the Trusted Computing Base, or TCB, that has approximately 300 lines of code, meaning that only these 300 lines of code need to be trusted in order to ensure the isolation offered by our approach. Previous techniques have exposed thousands of lines of code to potential attacks. We have a smaller attack surface to protect.”
