What is a DDoS attack and how can it be prevented?

In today’s technological world, cybersecurity threats continue to evolve, posing significant challenges for businesses, organizations, and individuals alike. One particular threat that has gained notoriety in recent years is Distributed Denial of Service (DDoS) attacks. As the digital landscape becomes more complex, the frequency and intensity of these attacks increase, leaving destructive consequences in their wake. What is a DDoS attack, and how can it be prevented in 2024? Read on for more information.


What is a DDoS Attack?

A DDoS attack is a malicious attempt to disrupt the normal functioning of a network, service, or website by overwhelming it with a flood of internet traffic. The attack is distributed because it involves a large number of compromised computers or devices, often forming a botnet, coordinated to send a massive amount of traffic to the target.

This surge of traffic overwhelms the target’s resources, making it difficult or impossible for legitimate users to access the network, service, or website. The goal of a DDoS attack is to disrupt the targeted entity’s operations, cause inconvenience, financial loss, or damage its reputation.


How are DDoS Attacks Executed?

To execute a DDoS attack, attackers often use a botnet – a collection of compromised computers or devices that can be remotely controlled by malicious software, turning them into zombies. Malicious software, such as viruses, spyware, worms, Trojan horses, etc., can be used to infect these devices.


Why Do DDoS Attacks Occur?

There are various reasons why individuals or groups launch DDoS attacks. One prevalent motive is the competitive advantage sought by different companies. For instance, Company X might launch a DDoS attack on the website of Company Y to disrupt its user traffic and, consequently, affect its revenue and market standing. DDoS attacks are also common in the competitive gaming sector, where gamers may use such attacks against rivals to gain an edge.


 Types of DDoS Attacks

  1. Server Protocol Attack – Also known as a protocol attack. It targets the way the server processes data, causing a significant load on the server’s resources.
  2. Application Layer Attacks – The most common DDoS attacks, where attackers attempt to gain access to the server or website like regular users, causing a gradual increase in request volume until the site cannot handle the load.
  3. Volumetric Attacks – Extremely impactful attacks, where the server’s bandwidth is exhausted due to a high volume of requests from the botnet. In some cases, the attack may cause the server to send requests to itself, leading to a loop and server crash.


How to Prevent DDoS Attacks in 2024

  1. Rate Limiting on the Server – Implemented to control the rate of incoming data. This proactive measure helps the server handle only a predefined rate of requests, preventing it from being overwhelmed.
  2. Avoid Oversubscription of Bandwidth – While increasing bandwidth might seem like a solution, it can be counterproductive in cases where you become a target for a DDoS attack. Avoid oversubscribing bandwidth, as it may make you more susceptible to large-scale attacks.
  3. Distribute Content Using CDN – Used to distribute content across multiple servers globally. This not only improves website performance but also reduces vulnerability to DDoS attacks. Even if one server is targeted, others in the network can continue functioning.
  4. Implement Proxy Servers – Used to act as intermediaries between user requests and the main server. This allows for a preliminary check of incoming requests before they reach the server, preventing illegitimate ones from affecting the server directly.
  5. Collaborate with Hosting Providers – Work closely with hosting providers who can offer additional protection and assistance during DDoS attacks. Providers may have specialized tools and expertise to mitigate the impact of such attacks.


Recognizing DDoS Attack Signs

It’s not always easy to detect a DDoS attack, especially on personal computers. However, for server hosting providers, signs may include frequent server crashes, prolonged loading times, and a significant increase in incoming requests.


DDoS Attack Types and Mitigation Methods


What to Do When Under Attack

If you suspect a DDoS attack

  1. Contact Hosting Provider – Immediately contact your hosting provider and inform them of the suspected DDoS attack. Providers often have measures in place to help mitigate such attacks.
  2. Engage Website Developers – Consult with your website developers or administrators to assess the situation and implement any necessary protective measures.



DDoS attacks remain a prevalent threat in the digital landscape. Implementing proactive measures and staying informed about the evolving nature of these attacks are crucial for safeguarding against potential disruptions. Whether through rate limiting, distributed content delivery, or collaboration with hosting providers, a multi-layered approach to cybersecurity is essential to mitigate the impact of DDoS attacks in 2024.
