The best intentions often lead to panic and congested e-mail systems. Most desktop computers now come with a security cable slot. To prevent unauthorized removal of your computer, loop a cable around an immovable object and lock the cable to the security cable slot with a padlock or other locking device. Anti-theft devices are of differing designs. Before purchasing such a device, make sure it will work with the cable slot on your computer.
Laptop computers are readily transportable and therefore are the most easily stolen.
Take care when traveling with a laptop as computer thieves are lurking in airports and hotels and have developed many creative schemes to separate you from your computer. The number one safety measure against theft of a laptop computer is to not let it out of your sight. When passing through airport checks, do not place your laptop on the conveyor until it is your turn to pass through the check. Follow your computer through the checkpoint. Do not leave your laptop with the hotel porter in the lobby.
