DDoS, or Distributed Denial of Services, is where a server or a machine’s services are made unavailable to its users.
And when the system is offline, the hacker proceeds to either compromise the entire website or a specific function of a website to their own advantage.
It’s kind of like having your car stolen when you really need to get somewhere fast.
The usual agenda of a DDoS campaign is to temporarily interrupt or completely take down a successfully running system.
The most common example of a DDoS attack could be sending tons of URL requests to a website or a webpage in a very small amount of time. This causes bottlenecking at the server side because the CPU just ran out of resources.
Denial-of-service attacks are considered violations of the Internet Architecture Board’s Internet proper use policy, and also violate the acceptable use policies of virtually all Internet service providers.
