Finally, a good deal of security comes from taking simple, physical precautions. Get a privacy screen for your laptop, and keep an eye out for “shoulder surfers”. Put a Post-it over your laptop and phone cameras when you’re not actively using them, and never let your devices out of your sight or loan them to anyone. The one exception to this may be in cases where you are meeting a source in person: Rather than turning your phone off, leave it at home or at work.
