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