What is a DDOs attack?

DDoS, or distributed denial of service, is a malicious attempt to make a website or network service unavailable by disrupting the traffic so that it cannot function.

DDoS Attack achieves efficiency by using vulnerable computer systems as sources of traffic attacks. Users may include computers and other network resources such as IoT devices. From a high point, the DDoS attack is like an unexpected traffic jam blocking the highway, preventing normal traffic from reaching our destination.

Types of DDOs Attacks!

Volumetric Attack

The goal of a volumetric attack is to use the botnet to generate a major amount of traffic and clog up the works on the target. Think of it as an HTTP Flood attack, but with an added exponential response component. For example, if you and 30 of your friends all called the same restaurant and ordered 60 plates at the same time, that restaurant will face difficulties and will not be able to fulfil those requests. Volumetric attacks operate on the same principle. They request something from the target that will vastly increase the size of the response, and the amount of traffic explodes and clogs up the server.

DNS Amplification is a kind of volumetric attack. In this case, they are attacking the DNS server directly and requesting a large amount of data back from the DNS server, which can bring the DNS server down and cripple anyone that is using that DNS server for name resolution services.

Protocol Attack

Attack of the DDoS Protocol targeted a network layer of targeted systems. Their goal is to cover the tablespaces for the main network services, firewall, or loading relay that transmits applications to the target.

Typically, network resources operate in a first-line. The first application comes in, the computer processes the request, and then it goes and finds the next application online, and so on. There are now a limited number of locations on this line, and in a DDoS attack, the queue may be so large that there are no computer resources to handle the initial request.

Application layer attack

The DDoS attack of the program layer is intended to exploit the services of the target and disrupt access to the targeted website or service. Attackers load the bots with a sophisticated application that taxes the targeted server as it tries to respond. The application may require access to a website or a large download. If the target receives a few million of those requests in a short period of time, it can be quickly frustrated and reduced to clarity or completely shut down.

HTTP Flood Attack, for example, is a web application attack that targeted the webserver and targeted many HTTP applications to slow down the server. Think of it as pressing the refresh button on the fire mode immediately in your game controller. That kind of traffic from many thousands of computers at once will quickly drown a web server.

In today’s cyber world, denial of service attacks is one of the most popular sports. Knowing the basic types and how to defend yourself against them is critical for a network administrator (or an individual) who wants to traverse the internet safely. Stopping a live DDoS attack can be difficult, and it may have an impact on your legitimate users. This is why it’s critical to take proactive measures.
