New Two-Headed Hard Drive Intended To Secure Web Sites

dlur writes: "This article states that Scarabs (In Japanese), a Japanese company, is developing a hard drive with two heads, one read-only and another that is read/write. With this comes two cables, the read-only side going to the external web server, and the r/w cable going to an internal protected server. While this should make it quite a bit tougher for script kiddies to place their mark on a page, I doubt it will stop any real hackers from getting to a site's DB as that would still need to be r/w."

The OS assumes that it, and it alone, modifies the disk, and that the disk won't change state without the OS making that change. This is one of the reasons you don't want to allow raw disk access from a VMWare or DOSemu session to a mounted file system - the emulated OS will access the disk, and the host OS's file system won't know about it. Boom! Instant corrupted file system.

There is this concept called drivers. It's the kind of thing that allows Windows 2000 to read, you know, FAT, FAT32, and NTFS file systems.

The same goes for, oh I don't know... Linux? We know how many file systems Linx supports, don't we?

Oh, and god forbid, what about NFS and Samba? Are the machines that host the NFS/Samba shares NOT allowed to change the contents of those systems?

Or what about, I don't know, a USB drive on your digital camera or MP3 player?

I'm not trying to be an asshole, but my point is this happens all the time and it's rather easy with the proper drivers installed.
