Well I can't explain it cause it doesn't exist. However, I guess just a box you plug in and it allows you control over processes (using an software interface of course) no different then a software hips, however, since it is hardware, it wouldn't be prone to being shutdown by malware as a software based hips would be!
I was just about to write that this is a silly idea, but then I read about Komoku (recently bought by M$) and guess what, they use a PCI Card to detect rootkits on the system, from outside the OS. But I´m not sure if this device can actually prevent rootkits from loading in the first place. They also offer a much cheaper software solution, btw.
Well Sandboxie isn't really virtualization, since it doesn't virtualize an enviroment, it is a sandboxing app. Also I don't know if I'd really consider Hypersight a virtualization app as well, more of a HIPS, even though it uses the hypervisor, it isn't quite virtualization though.
Wrong, you´ve got different types of virtualization. And Hypersight actually turns the whole OS into a virtual machine. It runs in a layer below the OS and has complete control, or something like this.
Anyways this is just my opinion about a hypervisor-HIPS, I just dont think it will work out real great in the end. I mean, hell, it can't even block rootkits...
I have to disagree, just because it´s software based doesn´t mean it´s crap. In fact, I would actually pay money for this stuff. AFAIK, it can detect AND prevent rootkits from loading. At least in theory, because I´m not sure if Hypersight already works correctly. Also, I´ve read that it can make use of security features from the processor (Intel Vanderpool/AMD Pacifica) plus a separate TPM chip to protect itself from attacks.
