You might have heard about DDoS Attacks, but do you know what DDoS attack actually is, how it works and how to prevent these attacks? If not then it is fine because in this article you are going to get complete information about it.

If you are a blogger then you must know about DDoS Attack and DDoS Attack Protection and you will also know how big a problem it is for Webmaster.

Thousands of websites are downed due to DDoS Attacks, even these DDOS Attackers have not left such websites.

So imagine how difficult it would be for a non-techy blogger to protect your website from DDoS.

Let us first know what is this thing and why is it such a big danger? What is DDoS? How does it work?

What is DDoS Attack?
The DDoS attack is a type of cyber attack which overloads the WordPress Hosting Server by sending multiple requests.

The full form of DDoS is Distributed Denial of Service attack. That is, DoS (Denial of Service) is an evolved form of Humo.
Under these attacks, attackers try to load the target website by sending DNS and HTTP requests to the server.

This means that it is an unfortunate attempt to attack a target website's server and disrupt its normal traffic and downgrade it.

Under these attacks, the infrastructure of the website is heavily damaged by bringing a flood of traffic to the hosting server. In this, the server goes down, sometimes the server crashes.

Now suppose, your website is a host on a server that can handle only 100-500 requests in realtime and its monthly limit to transfer data is 500GB or 1TB.

In such a situation, hackers will have to hack your site, then they will send a DDoS attack per second 1,000+ request to your site's server, and will override your month's data transfer limit in no time.

Meaning clearly, DDoS attack is a huge problem for WORDPRESS, the world's most popular blogging platform.

Let us know how it works?

In this type of attack, the website is downed by sending thousands of requests to the targeted server using various computers and devices.

They make a network called botnet by taking advantage of machines or servers spread across different regions. Each affected machine attacks the target server as a bot.

In this way, they send millions of requests to the target server in a short time, which the site server cannot handle and crashes, then the site stops working.

The world's largest and popular websites like Amazon, Netflix, PayPal, Visa and Github (popular coding website) have also hit it.

The problem of DDoS attacks was very less in 2003 but gradually it increased and in 2018 it increased by 90% compared to 2003, which means that there is now a lot of attrition.

If you do not want this type of problem on your website, then DDoS Protection has become necessary for your website.

But this is not an easy task, will you be able to set the request limit very easily, for a newbie blogger, this is a very difficult task.

That is why DDoS attacks are the best way to secure your site that you can activate WAF (Website Application Firewall) service for DDoS attack protection.

Some many websites and companies provide free and premium firewall service here. But among them, Cloud Flare, Sucuri.net service is the best.
