A DDoS attack consists of sending mass requests to a server or web service with the aim of overwhelming its processing capacity to prevent users from accessing the service.
What are DDoS attacks and what can be their consequences?
A distribut denial of service attack or DDoS (Distribut Denial of Service) is an extension of a denial of service (DoS) attack that is carri out by generating a large amount of information traffic or requests from multiple sources to a specific target.
The difference between the two is that a DoS
(Denial of Service) attack is characteriz by having a single origin, while a distribut attack comes from multiple origins, which makes attempts to block it more difficult and increases its effectiveness.
Both attacks consist of sending mass model retouching and simultaneous data packets to a specific target, usually a web server, affecting its processing capacity when it is exce and, consequently, it collapses. As a result, the services stop their normal operations and legitimate users cannot access the websites.
There are several tools or services available for carrying out a DDoS attack, although they are usually carri out through botnets, i.e., a malicious program that can be remotely controll by a cybercriminal. This type of malicious program consists of a control panel from which the actions to be carri out are execut and a server application that establishes communication with the cybercriminal’s control center. The particularity of botnets is that they allow an attacker to execute instructions on many computers infect with the malware simultaneously. In the case of a DDoS attack, the malicious programs are remotely instruct to make connections or requests to the target of the attack in a synchroniz manner.
DDoS: attacks against information availability
The traditional definition of information Стъпка: Започнете с въведение security is bas on preserving the confidentiality, integrity, and availability of information. Confidentiality is the property that allows information to be accessible only to entities that have the privileges and alb directory authorization; integrity is the property of maintaining the accuracy and completeness of information; while availability is the property that allows information to be available and usable whenever ne.
