what it is DDOS stands for distributed denial-of-service. And what does his it’s basically a cyberattack on a specific server or network with the intended purpose of disrupting that Network, or servers normal operation and a DDOS attack. Does this by flooding the targeted Network or server with a constant flood of traffic, such as fraudulent request which overwhelms the system causing A disruption in Oregon Isle of service to legitimate traffic.

DDoS attacks

So for example here, we have a web server, and let’s just say that this web server could belong to a company that sells their products over the internet and over here. We have a couple of shoppers with their computer systems which might be surfing the company’s web site having a look on the company’s merchandise or products and services. that let’s just say that someone just wanted to do an attack on this company’s web server. Let’s just say that they’re going to attack the server for whatever reason. as an example, perhaps they do not like the corporate or they don’t like the owners of the company or whatever. So what happens is the attacker is going to use their computer and their program to attack this server, and flood it with fraudulent data traffic to try and disrupt its service.

Now this is not a DDOS attack. This is simply known as a Dos attack which stands for denial of provider. because a Dos attack is an attack that just coming from One Source now normally a network or server is able to handle an attack from a single Source because it’s easier to pinpoint the server can just simply closed the connection where the attack is coming from. So that’s not really a problem. However, the issue is that what if an attack comes from a couple of resources simultaneously and that is what a DDOS is a DDOS is an attack from a couple of resources all at once. So this computer here who is the ringleader can communicate with other computers around the world and coordinate an attack on this server.

So now as a substitute of an attack coming from a single Source. the server now has to deal with an attack from multiple sources and when this happens it will overwhelm the server it will eat up as servers system resources such as the CPU and memory and it’ll additionally devour up Network bandwidth. So as a result these legitimate computers over here or going to be denied service because the server is too preoccupied and dealing with a DDOS attack. So the web pages that these computers want to access or either not going to load or they’re going to be very slow in loading and they’ll get that familiar Spinning Wheel of lag on their screens.

So the question is how does the attacker get other computers to get excited about a DDOS attack? And the simple answer is by using malicious software the attacker will develop a malware program and distributed over the internet and put it on things like website and email attachments. So if a vulnerable computer go to these infected website or open these infected email attachments. The malware might be installed on their pc with out the landlord even understanding that their pc has been infected. So now their computer has been recruited in a military of different inflamed computers to accomplish a DDOS attack, and this Army of inflamed computers is what’s known as a botnet. Now, this bought that is not just limited to a few computers. This bought that could be hundreds or even Thousands Oaks.

Scooters that are scattered all over the world. So now this botnet can be controlled like an army waiting to receive instructions from the attacker who is now like a centralized command and control center for the botnet and then the attacker can send out commands to all these computers and to tell them to attack at a certain date and time and then once that set time is reached the attack begins.

Now I did also attack can last for hours or even days. It just depends on the attackers intent. So every other query is why do people do DDOS attacks? DDOS attacks can occur for several different causes, for instance, it could be for monetary causes and the attacker is ddosing a competitor available on the market. It could also be for maybe political reasons. Maybe they don’t like the targeted organizations beliefs. or it could also be that maybe the attacker is just doing it for fun.
