1. Be watchful. Avoid talking shop on airplanes, in terminals or bars, locales where odds are the greatest that a competitor might be listening. If you have to discuss business, lower your voice and avoid top-secret subjects.

2. Be aware. When working on a laptop, never expose the screen in public. Avoid typing in an aisle seat or using anything larger than 12-point type.

3. Be on guard. People, on the exhibit floor, who are quite anxious to get strategic information on your company and new products, may surround you. If you need to have a meeting, consider renting a private room.

4. Be cautious. Remember, everyone can hear your conversation when talking business on pay or cell phones in public.

5. Watch your laptop. Don’t let your laptop out of your sight. If your computer contains sensitive files, purchase a cable lock or invest in security software that allows you to monitor your computer’s location at regular intervals. Consider encrypting your most sensitive files.

6. Keep sensitive materials to a minimum. Don’t take more company documents than you know you’ll need, and never read them in public places.
