How to Stop a DDOS Attack on Your Website

ddos attack A distributed denial of service (DDOS) attack is becoming more common against business websites every day. This type of attack consists of overloading your IP address with a huge amount of traffic. If the IP address leads to the web server, then even a cloud server may be overwhelmed which will cut off the legitimate traffic to your website. The result is that everything shuts down and your website is now unavailable.

The attack itself is rather simple in nature, but the general complexities that were faced in previous years have now passed and today, DDOS attacks have become fairly common. This is because it is easier to use different IP address sources to flood your website with unwanted traffic which usually occurs at the worst possible time.

However, thanks to new cloud hosting measures there are ways in which you can prevent such an attack from occurring. This will require preparation and the ability to react early so that a DDOS attack can be headed off before it shuts down your website.

How to Stop a DDOS Attack

Everything starts with knowing the basic type of traffic you get to your website. The better you know the type of traffic, the easier it is to spot a DDOS attack and take measures to stop it from shutting down your website.

Increase Bandwidth: This is one common method which can slow down the effects of an initial attack. The more bandwidth you have, the longer it will take a DDOS attack to shut down your website. This buys you time in reacting to an attack so you can take more measures.

Respond Quickly: If you see a surge in traffic that does not look like the normal type that visits your website, you can take quick action to block or handle this surge, including the following;

–       Add filters to drop packets from obvious malicious sources

–       Rate limit your router to prevent your cloud server from being overwhelmed

–       Lower the ICMP, SYN, and UDP thresholds

–       Get rid of malformed packages

By reacting quickly, you can blunt the effect of the attack before your server is affected. This will require monitoring the situation and having procedures in place, but if you are prepared than it can be done. However, even these measures are often not enough to stop a DDOS attack.

Call for Help: Your hosting provider should be contacted immediately at the first signs of a DDOS attack. If the attack is strong enough, they may have detected it and have already started to take measures. But the earlier you warn them, the better. The personnel who run the server are experienced with DDOS attacks and will be shunting away the obvious malicious traffic while keeping the legitimate ones heading towards your website.

Have a good relationship with your Cloud Provider: Ask your Cloud Provider to help you when you need it. You may not always be available to monitor your applications, so you could ask your provider to help you, solving your problem.

That’s why proximity is very important at the time of choosing a provider to host your application/website.
