While high-profile cyber hacks have made headlines around the world, a Lehigh University researcher is helping to ensure that businesses and government bodies of all sizes can keep their computers and network safe.
Gang Tan, Ph.D., an Assistant Professor of Computer Science and Engineering at Lehigh, is part of a group that is developing a system that retrofits existing computer software with security functions and enables software to remain secure after updates are installed.
The system would insert security checks to perform user authorization, authenticate users for software privileges, and monitor security needs for existing software.
Tan is working with a team that also includes researchers from Penn State University, the University of Vermont, and Rutgers University. The team received a four-year, $1.2 million grant recently from the National Science Foundation for the retrofit project.
Tan said in a published feature story that the new software would help businesses bolster their security while defraying costs and saving time instead of purchasing and installing redesigned software packages.
“Because so many software systems have been designed without enough attention to security, we believe it’s better to retrofit existing systems with better security checks,” Tan said. “There’s clearly a need for this.”
