Difference between applicative and network DDoS
A network DDoS’s and DoS’s main goal, as explained in the former paragraph, is to saturate the network connection of a server so that it cannot answer requests any more.
Applicative DDoS and DoS attacks, however, usually target a website one of whose pages takes a long time to load (for example, the one dealing with the indexation of a product catalogue, a Webservice method requiring a lot of resources or, simply, a highly charged functionally checkout page).
When it comes to DDoS attacks there’s no shortage of real-world examples. On October 21st, the DNS service Dyn underwent a large-scale attack on a global level. The attack utilized a massive botnet, assembled via open source code that took control of tens of thousands of IoT devices. These devices sent enough requests to overwhelm Dyn’s network resources, resulting in a textbook volumetric DDoS attack.
The massive influx of IoT devices presents a security challenge like nothing developers have yet faced. With an impressive lack of security and regulation, the IoT endangers not only local networks and personal computers, but the world of other connected devices. Having proper DDoS protection in place is more important than ever and will only continue to become a more pressing matter.
Some pages consummate a lot of CPU (processor) and RAM (main memory) resources in order to load, especially with interpreted (not compiled) languages like PHP. By calling this page several times per minute, it becomes quite easily possible, without a lot of machines, to block the targeted website.
