Protect Your Hard Drive

Rainer Mauth

Do you trust today's operating systems and firewalls to securely shield the data on your computer from hacking attacks and viruses? As recent incidents show, software is vulnerable to bugs that compromise security. That's why Calluna developed a "hardware firewall" that monitors all low-level hard disk activities and protects against illegal disk writes and accesses.

Called Hardwall, the card plugs into an ISA slot and operates separately from the system processor. It sets up firewalls at the boundaries of every partition on your hard disk and lets you define different levels of access. Because these firewalls operate separ ately on a low physical level controlled by Hardwall, the vendor says, they are impossible to penetrate and cannot be circumvented.

Hardwall also efficiently shields your system from viruses and accidental configuration changes. For example, it can set the boot partition of your hard disk to "write many recoverable" mode. This means that you may write to the partition as often as required during a session, but each time you reboot the machine, all changes are set back to the initial state. If information in this partition is infected by a virus or corrupted, the defect will be removed automatically upon rebooting. Hardwall is not virus-specific, so you don't need to update virus-scanning software.

Hardwall is an intelligent virus isolator and antihacking device that can work in a desktop PC as well as in a Windows NT server. Its big advantage is that it operates separately from CPU and OS and therefore doesn't degrade system performance.
