A Distributed Denial of Service (DDoS) attack is an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources. They target a wide variety of important resources, from banks to news websites, and present a major challenge to making sure people can publish and access important information.<\/span><\/p>\n

in <\/span>computing<\/span><\/a>, a <\/span>denial-of-service attack<\/b> (<\/span>DoS attack<\/b>) is a <\/span>cyber-attack<\/span><\/a> where the perpetrator seeks to make a machine or network resource unavailable to its intended <\/span>users<\/span><\/a> by temporarily or indefinitely disrupting <\/span>services<\/span><\/a> of a <\/span>host<\/span><\/a> connected to the <\/span>Internet<\/span><\/a>. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.<\/span>[1]<\/span><\/a><\/p>\n

In a <\/span>distributed denial-of-service attack<\/b> (<\/span>DDoS attack<\/b>), the incoming traffic flooding the victim originates from many different sources. This effectively makes it impossible to stop the attack simply by blocking a single source.<\/span><\/p>\n

A DoS or DDoS attack is analogous to a group of people crowding the entry door or gate to a shop or business, and not letting legitimate parties enter into the shop or business, disrupting normal operations.<\/span><\/p>\n

Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile <\/span>web servers<\/span><\/a> such as banks or <\/span>credit card<\/span><\/a> payment gateways<\/span><\/a>. <\/span>Revenge<\/span><\/a>, <\/span>blackmail<\/span><\/a>[2]<\/span><\/a>[3]<\/span><\/a>[4]<\/span><\/a> and <\/span>activism<\/span><\/a>[5]<\/span><\/a> can motivate these attacks.<\/span><\/p>\n

DDoS<\/i><\/b> is short for <\/span><\/i>D<\/i><\/b>istributed <\/span><\/i>D<\/i><\/b>enial <\/span><\/i>o<\/i><\/b>f <\/span><\/i>S<\/i><\/b>ervice. <\/span><\/i>DDoS is a type of <\/span>DOS attack<\/span><\/a> where multiple compromised systems, which are often infected with a <\/span>Trojan<\/span><\/a>, are used to target a single system causing a<\/span>Denial of Service<\/span><\/a> (DoS) attack. Victims of a DDoS attack consist of both the end targeted system and all systems maliciously used and controlled by the hacker in the distributed attack.<\/span><\/p>\n

How DDoS Attacks Work<\/i><\/b><\/h2>\n

In a DDoS attack, the incoming traffic flooding the victim originates from many different sources \u2013 potentially hundreds of thousands or more. This effectively makes it impossible to stop the attack simply by blocking a single IP address; plus, it is very difficult to distinguish legitimate user traffic from attack traffic when spread across so many points of origin.<\/span><\/p>\n

The Difference Between DoS and DDos Attacks<\/i><\/b><\/h2>\n

A Denial of Service (<\/span>DoS<\/span><\/a>) attack is different from a DDoS attack. The DoS attack typically uses one computer and one Internet connection to flood a targeted system or resource. The DDoS attack uses multiple computers and Internet connections to flood the targeted resource. DDoS attacks are often global attacks, distributed via <\/span>botnets<\/span><\/a>.<\/span><\/p>\n

Types of DDoS Attacks<\/i><\/b><\/h2>\n

There are many types of DDoS attacks. Common attacks include the following:<\/span><\/p>\n
