DDoS Attacks Directed Against:

Network Bandwidth

Network Bandwidth relates to the capacity of the networks connecting a computer or a server to the wider internet. For most organization this is their connection to Internet Service Provider (ISP), if the capacity of links within and between ISP routers is lower than the amount of traffic passing within and between these links then it leads to Denial of Service for the organization

System Resources

A DoS attack targeting system resources typically aims to overload or crash its network handling software. Rather than consuming bandwidth with large volumes of traffic, specific types of packets are sent that consume the limited resources available on the system. These include temporary buffer used to hold arriving packets and tables of open connections.

Application Resources

An attack on a specific application, such as a Web server, typically involves numbers of valid requests, each of which consumes significant resources. This then limits the ability of the server to respond to requests from other users. This type of attack is also known as cyberslam.
