DDoS Attacks: How to prevent the least and handle the worst
IntroductionDo you know how much an hour of downtime costs for your business? Statistics say, that depending on the size of the enterprise, the numbers can go up to $40,000 per hour of offline state. The more devices can be used to access your website and store — from desktops to Smart TVs, the more vulnerable the system becomes. Expanding your business to new sales channels feels great, but comes with a danger you might not be ready for. In this article, we will talk about ‘distributed denial of service’ attacks: what they are, how they work, and what you can do to stay invincible.
What is a DDoS attack?When a DDoS attack happens, your website becomes unavailable due to overwhelming web traffic from different sources at the same time. It looks very similar to the situations your online store deals with on Black Friday, Christmas, and New Year eves, when accidental peaks of activity can make your store servers go down for some time.But DDoS attacks are performed to break down your site by crashing its infrastructure. Therefore your site becomes unavailable for an uncertain period of time, and your customers are not able to buy anything from you during that period of time. What is more, DDoS attacks can go unnoticed for quite a long time, and you wouldn’t be able to provide customer support while your website or application is down. No sales, no feedback, drop-in visitors, and a damaged brand reputation is the result of a successful DDoS attack.DDoS attacks come in form of thousands of repetitive requests coming from different compromised IP addresses. IP blocking isn’t the cure, since there are too many of them to track, and sometimes they are hard to distinguish from the legitimate traffic. Powerful servers are not the ultimate solution anymore, as internet access is coming to more and more devices, making it easier to plan knockdown attacks on websites.
What is at stake in the case of DDoS attack?One in five customers says that they won’t return to the online store they had troubles with. Сconversion rates highly depend on your website speed and availability. A suspiciously slow online store throwing an error message every other time is the last thing that When you are offline, you can’t make money anymore. Another underestimated danger is that no matter how small your business is, or how competitive your market is, it can happen to your store. The attackers can strive for you for different reasons: they can blackmail you for money or carry out someone’s order to bring you down. It is indeed good to remember that most ecommerce companies have experienced a DDoS attack at least once in the past, and 40% of ecommerce business owners still don’t know how to handle or prepare for a DDoS attack. What makes every ecommerce website vulnerable are targeted attacks on DNS providers. They can result in downtime for hundreds of websites. Is there anything you can do?Protection from DDoS attacks must be a stable part of your online security strategy. If well-known and huge companies like BBC, GitHub, OVH have suffered and weren’t able to foresee and defeat an attack, how smaller enterprises and companies can? There are a few ways to prepare and fight off possible threats.
- Learn to recognize attacks when you see them
- Filter data traffic in as many ways as possible
- Make sure to dump log files during DDoS attack
- Plan a response to a DDoS attack before it happens
