What is a DDoS attack and how to mitigate it?
Datacenter.com – A Distributed Denial-of-Service (DDoS) attack is a malicious attempt to disrupt the traffic of a targeted server, service or network by overwhelming it with a flood of internet traffic (Cloudflare, 2019).

DDoS attacks are much like traffic on a highway. Imagine regular traffic moving at a steady pace and cars on their way to their desired destination. If a flood of cars enters the highway at a particular point, it significantly delays or prevents the cars behind them from reaching their destination at the time they should.

In 2018, more than 400,000 DDoS attacks were reported worldwide (CALYPTIX, 2018). In 2018’s 4th quarter, Great Britain was responsible for 2.18% of these attacks, a staggering difference compared to 2019’s 1st quarter of 0.66% (Gutnikov, 2019).

The goal of this attack is to create congestion by consuming all available bandwidth utilized by the target to access the wider internet it wishes to interact with (Cloudflare, 2019). Large amounts of data are sent to the target by utilizing a form of amplification or another means of creating massive traffic, such as requests from a botnet (which is a group of devices infected with malware that an attacker has remote control over). more>
