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.
"I'm just here to regulate funkiness."
But does it run... oh, right.
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?
Give me Classic Slashdot or give me death!
Now, I might be nieve but why can't these memory aligning tricks be done in the kernel naively?
My spelling error detector just exploded! You jerk!
No, it's a lie. It's not possible to build a rootkit for linux, it's magical.

Damn, my RAM is full of llamas.
I think you had a little typo there, but I fixed it.

You're either insulated, or you suck at humor. By your logic windows boxes get administratored.
Well, with some of the messes I've had to clean up from previous Admins it isn't an unfair statement
