PREDATOR locks your PC when you are away, even if your Windows session is still active.
It uses a regular USB flash drive as an access control device, and works as follows:
How Predator works:
- you insert the USB drive
- you run PREDATOR (auto start with Windows is possible)
- You do your work…
when you’re away from your PC, you simply remove the USB drive:
– once it is removed, the keyboard and mouse are disabled and the screen darkens
When you return back to your PC, you put the USB flash drive in place:
– keyboard and mouse are immediately released, and the display is restored.
Some features of Predator
PREDATOR can protect several PCs with the same USB flash drive, e.g. your home and office computers.
PREDATOR can protect several user accounts on a PC, each one having its own settings and its own USB stick.
PREDATOR can lock user accounts according to an hourly, daily or weekly schedule, each one with its own timetable.
PREDATOR can send alert messages by Email.
PREDATOR can take pictures of the person who tries to use your computer and attach them to an email or upload them to a remote server.
PREDATOR records all security-related events in a log file: start, alarms, stop. By reading this log, you will know if intruders have tried to use your computer while you have been away.
PREDATOR frequently changes the security codes recorded on your USB drive. If an intruder manages to copy your stick, this copy will not work because the codes on your own stick will have changed in the meantime.
PREDATOR protects its own in-memory process. Nobody can stop it with Ctrl-Alt-Del.
PREDATOR disables the CD Autorun feature in Windows, to prevent intruders from running malware on specially crafted CDs.
How to use Predator
Step 1: Download and install Predator from their website
Step 2: After downloading, launch and plug in your USB flash drive. None of the contents of the drive will be deleted or altered in any way, so feel free to use your primary thumb drive.
When you insert the drive, a dialog box will appear asking you to create a password. Click OK to continue.
Step 3: In the Preferences window, take note of a few key settings. First, enter a secure, unique password in the “New password” field. If you lose your USB drive, you’ll use it to unlock your computer.
If you’d like, you can check the Always Required box and you’ll be asked to enter the password each time you use your thumb drive to unlock your PC.
Finally, in the section under Flash Drives, ensure that the correct USB flash drive is selected. When you’re done, click “Create key” and then OK.
Step 4: Predator will exit. When it does, click the Predator icon in the taskbar to restart the program. A few seconds later, the icon will turn green, alerting you that Predator is running.
Every 30 seconds, Predator will check to see that your USB drive is plugged in. If it isn’t, your computer will dim and lock down.
