Hardware, Software Advances Help Protect Operating Systems From Attack

View as: Print Mobile App Share:

North Carolina State University (NCSU) researchers have developed a system that utilizes hardware and software to restore an operating system (OS) if it is attacked. The researchers are focusing on attacks involving compromised computer applications, such as Web browsers that can then be used to access the OS. "Our approach has three components — attack detection, security fault isolation, and recovery," says NCSU professor Yan Solihin.

The method works by analyzing the OS when it is functioning properly and rechecking it at different points in time. If the system is found to be compromised or not working properly, it will erase everything that has been done since the last "clean" check, in addition to identifying the source of the attack.

"We've developed hardware support that allows the OS to incorporate these survivability components more efficiently, so that they take up less time and energy," Solihin says.
