Scientists Unveil Lightweight Rootkit Protection

DangerFace writes "Scientists are set to unveil a lightweight system they say makes an operating system significantly more resistant to rootkits without degrading its performance. The hypervisor-based system is dubbed HookSafe, and it works by relocating kernel hooks in a guest OS to a dedicated page-aligned memory space that's tightly locked down. The team installed HookSafe on a machine running Ubuntu 8.04, and found the system successfully prevented nine real-world rootkits targeting that platform from installing or hiding themselves. The program was able to achieve that protection with only a 6 percent reduction in performance benchmarks."

    I would gladly give up 6% of the performance of my machine if I could be safe from rootkits. Now queue the "those who would give up system performance for system security deserve neither" posts.

      Damn straight! The same goes for guns! It should be a law that computer admins have to carry guns in order to protect their machines! Have a computer in your house? Well then, you are required to have a gun by your machine - even if you live in NY City!

      Those who would give up essential system performance for temporary system security... probably need to learn how to overclock their systems.

    So this thing acts as a hypervisor and loads its own hooks into the kernel. Sounds like something a root kit would do.

    It reminds me of one approach to avoid a terrorist attack when flying. Carry your own bomb onto the plane. After all, what are the chances that there would be two bombs on the plane?

      That's why the TSA's so harmful. If you outlaw bombs on a plane, then only terrorists will have bombs.
