What does DDoS, the Distributed Denial of Service mean?
A Distributed Denial of Service (DDoS) is a type of computer attack where multiple hosts overload a server. The result is a complete system crash on site.
This type of service attack is committed by hackers looking to attack large, wide-ranging websites. The goal is to temporarily or permanently disable them.
This is often achieved by bombarding the target server with information requests, which deactivates the main system and prevents the main system from operating.
This prevents users of the website from accessing the target page. DDoS differs from a Denial of Service (DOS) attack in that it uses multiple hosts to bombard a server
A Denial of Service attack, on the other hand, attacks using a single host.
Procedure of a DDoS Attack
In a standard attack, an attacker starts the process by exploiting a vulnerability in a computer system. The hacker turns this compromised computer into a DDoS master.
With this master system, the hacker detects, communicates and infects other systems. This makes them part of the compromised system. A compromised computer system under hacker control is called a zombie or bot.
A number of compromised computers is called a zombie army or a botnet. The hacker loads several crack tools onto sometimes thousands of systems.
With a single command, the attacker instructs these zombie machines to initiate multiple flood attacks on a single target. This packet flooding process causes a denial of service.
In a DDoS attack, the victim is not solely the ultimate target. All compromised systems are victims in this type of attack.
