CYBER SPACE
Cyberspace has long been deemed the “5th theatre of war” with an attack surface that is increasing year after year. New devices are connected and disconnected every day creating a changing landscape for potential adversaries. Imagine trying to defend landscape that is constantly changing. When you plug one electronic device into another, the landscape changes. The Universal Serial Bus (USB) drive is an electronic device that you plug in to transfer files, pictures, movies, and sometimes malicious code. Many companies are disabling USB storage drives in an effort to defend and reduce their attack surface. However, mice, keyboards, or other mobile devices connected via USB are often allowed. Protect yourself from transferring malicious code by following these tips: 1. Never plug in USB devices you have found. 2. Avoid using USB drives owned by others. Instead, stick to hardware with which you are familiar. 3. Bring your own charger with you on trips, and avoid public USB charging stations. 4. Charge your device with an outlet, not a computer or smart refrigerator. 5. Keep patches updated on your mobile devices and computers. 6. Think before you plug one of your devices into another microprocessor. (Microprocessor: an integrated circuit that contains all the functions of a central processing unit.)
