DDoS attacks are launched online with “toolkits” specifically designed to cause such attacks. One of the most well-known toolkits, an early version, was named after the Ion cannon, a fictional weapon in a video game franchise known as Command & conquer, the Low Orbit Ion Cannon (LOIC) is an open source network stress testing and DDOS attack application that is used by client machines to voluntarily join botnets.
A distributed denial of service attack refers to a flood of data traffic that a server receives when multiple systems send in data with an aim of flooding its bandwidth or resources. In most cases, this data flood is intended at disrupting the receiving of legitimate traffic by the server, ‘denying service’ to clients sending requests to the server. To an end user, when a DDOS attack seems like a service request delay, where new connections are no longer accepted.
