Firewall for Your Hard Drives
DriveSentry, by Drive Sentry Inc., creates a white list of programs that are allowed to write to your hard drives.
If any program that is not on the list attempts to add or modify a file on your hard drive, Drive Sentry will intercept that action and ask for your input on the matter. If a virus or other malicious program is attempting to access your files, you have an opportunity to block it. Quite handy.
DriveSentry can also be used to prevent rootkits and keyloggers from writing to the hard drive, and it works with peripheral storage devices like USB drives.
DriveSentry is available for download from the maker at the following link: http://www.drivesentry.com/index.htm
We haven’t tried this program yet, but plan to give it a test in the near future. It looks promising.
