Distributed Denial of Service (DDoS)

A Distributed Denial of Service (DDoS) attack is a type of cyber attack where the attacker floods a targeted system or network with traffic, making it difficult or impossible for legitimate users to access the system. The traffic comes from multiple sources, making it difficult to identify and block the attacker. DDoS attacks can target a wide range of systems and networks, including websites, servers, and even IoT devices.There are several types of DDoS attacks, including:- Volumetric Attacks: These attacks flood a targeted system or network with a high volume of traffic, overwhelming the system's capacity to handle it.- Protocol Attacks: These attacks exploit vulnerabilities in network protocols, causing the targeted system to consume excessive resources or crash.- Application-layer Attacks: These attacks target specific applications or services running on a system, attempting to exhaust their resources or exploit vulnerabilities.- Hybrid Attacks: These attacks combine multiple DDoS attack types to create a more complex and sophisticated attack.Examples of DDoS attacks include the 2016 Dyn cyberattack, which targeted the domain name system (DNS) provider Dyn, resulting in widespread outages for several hours. Another example is the 2018 GitHub DDoS attack, which used a new technique called Memcached amplification to create a massive amount of traffic aimed at the code-sharing website GitHub. In 2021, there was a series of DDoS attacks targeting the gaming industry, resulting in disruptions and downtime for multiple popular gaming platforms
