It’s an unfortunate fact that for every nice person that’s out there on the Internet, there’s always going to be someone looking to cause trouble. That trouble commonly comes in the form of a DDoS (distributed denial of service) attack, and when this happens it can cause some serious issues with a website. If you’ve ever been on the receiving end of a DDoS attack, you likely know this. If you haven’t, you should be aware of just how inconvenient and damaging this kind of attack can be. If you’re managing an online retail site, for example, a DDoS attack could put a serious dent in both your site traffic and sales, which means you’re losing money by the minute as the attack continues. In order to avoid this kind of scenario (or at least to be able to stop it from being too damaging) it’s a very good idea to be aware of just what you can do to try and prevent a DDoS attack.
Buy More Bandwidth Than You Need
One of the easiest ways to prevent the severity of a DDoS attack is to buy more bandwidth than you need. Unfortunately, this is going to cost you. The reason you’re going to want more than you need is that a DDoS attack focuses on bombarding your site with insane amounts of traffic, which in turn overwhelms your bandwidth. If you have the excess bandwidth, however, it means that the attack may not work as the person or persons behind it had planned. This isn’t a sure-fire prevention method, though; some DDoS attacks could consist of unbelievably massive amounts of traffic being hurled at your site, and if that’s the case you’d need far more bandwidth than you could realistically have access to in order to be unaffected.
Have a Plan of Action in Order
Just because you don’t think you’d ever be on the receiving end of a DDoS attack doesn’t mean it won’t happen. A large part of prevention is making sure that you’re ready to act the moment you suspect your website is under attack. This means that you should have the contact info for either your ISP or your hosting provider easily available. The sooner you can get into contact with your provider/ISP, the faster you can work together toward taking steps that can either mitigate the attack or deny it all together. You should also be familiar with the warning signs of an impending attack, and one of the most obvious is a sudden, huge spike in site traffic. Get familiar with the traffic patterns on your site. Once you do this, you’ll be easily able to spot a pattern that looks unfamiliar compared to how traffic usually is.
Make Use of a Cloud-Based Solution
There are some programs out there that specialize in DDoS prevention. These are usually cloud-based and function by acting as an absorption shield that can soak up the DDoS traffic that’s intended for your website. This protective feature is always turned on, which means that you won’t need to activate it once you know an attack is underway as it will already be functioning. These protection programs can also include additional defensive measures that can protect your DNS from being attacked and overwhelmed.
