Explaining DDoS Attack and how to protect your site from it

Nowadays, websites and online platforms are increasingly becoming targets of cyber attacks and a Distributed Denial of Service (DDoS) attack is one of the most widespread and destructive forms of cyber attacks. DDoS attacks are designed to flood a website's servers with a flood of fake traffic, making the website inaccessible to its users. In this article, we'll dive into DDoS attacks, the impact they can have on a website, and most importantly, measures you can take to protect your WordPress site from DDoS attacks.

From understanding the basics of DDoS attacks, to implementing security measures and best practices for keeping a DDoS-safe website, this article will provide a comprehensive guide to protecting your site. What are DDos attacks? DDoS is known as a denial of service attack, which is a type of electronic attack that aims to disrupt the normal course of operation of the target party's server, services, or network. Attackers use a large number of compromised computers and devices, also known as botnets, to send a large number of requests to the targeted server.

The main goal of these types of attacks is to make a website or service unavailable to its users, by flooding the server with a flood of requests. The attack achieves its goal after making the server unable to respond to user requests, which ultimately leads to the service crashing or being temporarily unavailable. How DDoS Attacks Work DDoS attacks involve using a large number of compromised devices to overwhelm a server at the same time. The attacking device creates a botnet known as “botnets” by infecting many computers from different parts of the world with malware and controlling them as a group without the knowledge of the owners.

The attacking device forms the control unit that sends commands to the attacked devices on a specific day and time, and at the planned time, the attack on the targeted server begins from all devices at the same time. Which constitutes confusion and disruption to the server’s workflow, consumption and damage to server resources such as the central processing unit and memory, in addition to consuming network bandwidth, which results in the computer connected to the targeted server facing a block of services, as the massive influx of DDoS attack will prevent the server from responding to its requests. The first DDoS attacks were reported in 1999. The attacks continued and mainly targeted prominent websites including Yahoo, Amazon, and eBay.

As technology advances, attackers begin to use botnets and networks of compromised devices to launch more powerful attacks. With the advent of the Internet of Things (IoT), the number of devices that can be compromised and used in DDoS attacks has increased dramatically. Nowadays, DDoS attacks are becoming more frequent and powerful.
