 Each morning thousands of people around the globe wake up with one job to do. Steal our secrets and technology. And prepare to cripple us in the event of war. How? By targeting you. Constantly. Each and every day our adversaries are looking for your weak spot. An easy entry into our system. Remember those files you transferred to your home computer? That phone you plugged into your computer to charge? Passwords you never change? These actions aren't harmless. They can cost us lives. From our nuclear arsenal to the phones allowing our war fighters to communicate. On the ground, in the air, and at sea. Computers are essential to everything we do. And keeping these systems secure is everybody's job. We need your help. You are on the front lines of this fight. Yes. You. You are a war fighter in the cyber domain. A Sentinel for the department and nation. Take this month to educate yourself on the threat we face. And what you can do to turn back the enemy. Start by doing these three simple things. Update your security software. Set up multi-factor authentication. Change your passwords. This is not a drill. This is a fight. What role will you play?
