Let’s pretend that you are a system administrator at a small business that is located in the south of the United States somewhere. The exact state and location is not important because an attack like the one that we are about to describe can happen anywhere. I am just setting up the mood.
So let’s pretend that you are monitoring your network one day and all of the sudden you start to see a boost of traffic. Now you are starting to think to yourself why is this boost happening? Has your company offered a new product that has everyone excited? Did some news happen about your company while you were asleep last night? No, you don’t think so but now you are starting to notice that something weird is happening. You are no longer getting a huge amount of traffic; you are starting to become overloaded. And it just will not stop.
What happened is not that you have become suddenly popular. What happened is that you have just been hit with a massive cyber attack. This type of attack is known as a DDOS attack. The letters DDOS stand for Distributed Denial of Service attack. This means that some hacker that you do not know about got control of hundreds of zombie computers from around the world and they have attacked your network. The attack on their end is going off without a hitch and now you are not able to get any legit users to your servers. To the outside world your web site is completely shut down.
DDOs attacks happen all of the time and there is a reason why. The reason why is because they are pretty hard to stop. While some ISP’s have found ways to limit the effect that a DDOS attack has, it still can cause a lot of damage to your network. You not only have the loss of revenue that happens when people cannot get to your website but you also have the extra bandwidth costs that you must now deal with.
As a system network administrator, DDOS attacks are bound to happen. You just have to learn how to recognize them and know what to do when they do happen. This way you can limit the effects that they do have. You may also want to initiate a DDoS policy.
