Application layer DDoS attack : ウィキペディア英語版 | Application layer DDoS attack
An application layer DDoS attack (sometimes referred to as layer 7 DDoS attack) is a form of denial-of-service (DDoS attack) where attackers target the application layer of the OSI model. The attack over-execises specific functions or features of a website with the intention to disable those functions or features. This application-layer attack is different from an entire network attack, and is often used against financial institutions to distract IT and security personnel from security breaches. As of 2013, application layer DDoS attacks represent 20% of all DDoS attacks. According to research by the company Akamai, there have been "51 percent more application layer attacks" from Q4 2013 to Q4 2014 and "16 percent more" from Q3 2014 over Q4 2014.〔https://blogs.akamai.com/2015/01/q4-2014-state-of-the-internet---security-report-some-numbers.html〕 ==Application layer== (詳細はApplication layerを参照) In the OSI model, the definition of its application layer is narrower in scope. The OSI model defines the application layer as being the user interface. The OSI application layer is responsible for displaying data and images to the user in a human-recognizable format and to interface with the presentation layer below it.
