How to block a DDoS attack ?

A DDoS attack can bring your website to a halt, reduce your search engine rankings and of course cause the loss of your data. Even with protective measures, there is no such thing as 0 risk. Here’s how to block a DDoS attack.

Overbudgeting for bandwidth

One of the quick ways to stop a DDoS attack is to expand your bandwidth as soon as you notice a sudden and unexplainable increase in traffic volume to your site. Most web hosts allow you to quickly expand your bandwidth and handle an additional traffic spike. This will buy you time to find the source of the attack and counter it completely, do you want to know more about security ? If so, click here.

Protect your network perimeter

In the first few minutes after a DDoS attack, there are a few technical measures that will help you mitigate the effects. For example, you can limit your router throughput to prevent your web server from being overwhelmed, add filters to tell your router to drop packets from obvious attack sources, time out half-open connections more aggressively, drop spoofed or malformed packets, set lower thresholds for SYN, ICMP, and UDP flood removal.

Contact your hosting provider

Depending on the strength of the DDoS attack, the hosting provider may have already detected it or it may even be the target. Its data center probably has larger bandwidths and higher capacity routers than your company’s. Their staff also has experience in dealing with cyber threats. So don’t hesitate to notify them as soon as the attack begins. The hosting company can “route block” your traffic to prevent packets from reaching your site. 

In order to counter and block DDoS attacks before they happen, hire a cybersecurity expert by posting an ad on their site. They will be able to help you secure your computer network and your website to the maximum extent possible.
