A major cyber attack hit the East Coast October 21 and spread to the West Coast. Sites like Twitter, Netflix, and VISA were reportedly down.In CERT training we talk about keeping cash on hand in the event of a disaster, but we don’t really talk about it for cyber attacks. What if you can’t access your ATM or bank account? Something to keep in mind. Keep small bills – you may not be able to get change. Start saving now. When you get home every day, take the dollar bills you have and set them aside. Every week, set aside a couple of five dollar bills or a ten dollar bill. They will add up.
