Understanding DDoS Attacks and Their Impact on Websites

Introduction:

Denial-of-Service (DoS) attacks have been a major concern for websites and online services for years. However, Distributed Denial of Service (DDoS) attacks are a different story altogether. A DDoS attack is an attempt to make a website or service unavailable by overwhelming it with traffic from multiple sources. In this article, we will explore the concept of DDoS attacks, their impact on websites, and how they differ from traditional DoS attacks.

The Biggest Ever Recorded:

One of the most significant recorded DDoS attacks was the Mirai botnet attack in Autumn 2016. This attack generated over 1 terabyte per second of traffic, making it one of the largest ever recorded. According to a study, 34% of DDoS attacks clock in at between 100 MB's to 1 GB's, while only 5.3% exceed the 10 GB/s mark.

Impact on Websites:

A 1 GB/s denial-of-service attack is strong enough to take down most websites due to their limited bandwidth. Most data hosting services do not offer enough bandwidth to keep a website online during such an attack. In fact, according to this study, 82% of DDoS attacks last less than 4 hours.

How DDoS Attacks Work:

A DDoS attack typically sends information from one source, but a DDoS attack uses thousands or hundreds of thousands of sources to flood its target. The point of these exercises is to take down a website or service by flooding it with more information than the victim website can process.

What Does DDoS Stand For?

DDoS stands for Distributed Denial of Service, which is the bigger brother of simpler denial-of-service attacks. In simple terms, a DDoS attack is an attempt to overwhelm a website or service with traffic from multiple sources, making it unavailable to users.

In conclusion, DDoS attacks are a serious concern for websites and online services. They can be devastating, causing significant downtime and financial losses. Understanding the concept of DDoS attacks and how they differ from traditional DoS attacks is crucial in developing effective strategies to prevent and mitigate their impact.
