Different cyber attacks series 2 of 4
What is DOS attack?
The Denial of Service (DOS) attack involves attacking a targeted system or server with huge amount of request’s made recursively that eventually slow down the victims computer system or server.
This requests overwhelm and consume all available resources and bandwidth, denying legitimate users access to the service.
Goal of Dos attack’s
- To saturate the target machine or network with external communication requests, so it cannot respond to legitimate traffic or requests.
- To force the targeted computer or network to reset or consume its resources so that it can no longer provide its intended service.
There are different types of DoS attacks, including:
- Traffic flooding attacks: The attacker overwhelms the target with useless internet traffic to exhaust bandwidth or resources.
- Crash attacks: The attacker sends malformed data packets to crash the operating system or application.
- Distributed Denial of Service (DDoS): An attack comes from many distributed systems making it more difficult to mitigate.
Understand DDoS attack
A Distributed Denial of Service (DDoS) attack is an attempt to make an online service or a website unavailable by overloading it with huge floods of traffic generated from multiple sources.
Unlike a Denial of Service (DoS) attack, in which one computer and one Internet connection is used to flood a targeted resource with packets, a DDoS attack uses many computers and many Internet connections, often distributed globally in what is referred to as a botnet.
A large-scale volumetric DDoS attack can generate a traffic measured in tens of Gigabits (and even hundreds of Gigabits) per second. A DDoS (Distributed Denial of Service) attack is a type of cyber attack where multiple compromised computer systems, also known as botnets, are used to flood a targeted website, server or network with a large amount of traffic, overwhelming its capacity to respond to legitimate requests.
