Denial of Service Attacks (DoS Attacks) involve flooding a computer with more requests that it can handle. This causes the computer or web server to crash and results in authorized users being unable to access the service offered by the computer.
Another variation to a typical denial of service attack is known as a Distributed Denial of Service (DDoS) attack wherein the perpetrators are many and are geographically widespread.
Incident 1
A series of distributed denial of service attacks in February 2000 crippled many popular websites including yahoo.com, amazon.com and cnn.com.
Incident 2
A series of more than 125 separate but coordinated denial of service attacks hit the cyber infrastructure of Estonia in early 2007. The attacks were apparently connected with protests against the Estonian government's decision to remove a Soviet-era war memorial from the capital city. It is suspected the attacks were carried out by Russian hackers. The attacks lasted several days.
