DoS
DoS stands for Denial of Service. It is a type of attack on a service that disrupts its normal function and prevents other users from accessing it. The most common target for a DoS attack is an online service such as a website, though attacks can also be launched against networks, machines, or even a single program.
What is DDoS(Distributed Denial of Service)?
Distributed Denial of Service (DDoS) is a type of DOS attack where multiple systems, which are trojan infected, target a particular system which causes a DoS attack.
A DDoS attack uses multiple servers and Internet connections to flood the targeted resource. A DDoS attack is one of the most powerful weapons on the cyber platform. When you come to know about a website being brought down, it generally means it has become a victim of a DDoS attack. This means that the hackers have attacked your website or PC by imposing heavy traffic. Thus, crashing the website or computer due to overloading.
Example: In 2000, Michael Calce, a 15-year-old boy who used the online name “Mafiaboy”, was behind one of the first DDoS attacks. He hacked into the computer networks of various different universities. He used their servers to operate a DDoS attack that brought down several websites such as eBay and Yahoo. In 2016, Dyn was hit with a massive DDoS attack that took down major websites and services such as Netflix, PayPal, Amazon, and GitHub.
