12-13-96 "A hardware device may offer a solution to software virus problems" Calluna, a Scottish disc drive company, has developed a hardware product which it believes offers computers complete protection against viruses. It consists of a microprocessor on a small circuit board which is placed between the PC's hard disc drive and its system board, and which functions independently of the PC's own CPU as a second CPU. The microprocessor can be programmed to monitor all traffic being routed to the PC's hard disc drive. If it detects virus-like activity or any other illegal activity it alerts the user and allows the option of blocking access to the hard disc drive. The second CPU could also be allocated partitioned sections of the computer's hard drive to store all material downloaded from the Internet. Or the device could be used as a firewall to prevent unauthorised access to the PC's hard drive. [Might this have crypto use?] ----- CPU_two
