In this book, the authors shed light on a form of computer attack that impacts the confidentiality, integrity, and availability of computers worldwide. Suddenly your Web server becomes unavailable. When you investigate, you realize that a flood of packets is surging into your network. You have just become one of the hundreds of thousands of victims of a distributed denial-of-service DDoS attack, a pervasive and growing threat to the Internet. What do you do?

The Attack That Could Disrupt The Whole Internet - Computerphile

Internet Denial of Service Attacks and Defense Mechanisms

Ever expanding array of schemes for detection and prevention of Distributed Denial of Service DDoS attacks demands for a constant review and their categorization. As detection techniques have existed for a relatively longer period of time than defense mechanisms, researchers have categorized almost all the existing and expected forthcoming attacks. However, techniques for defense are still nurturing. Researchers have explored that there could be diverse ways of launching DDoS attacks. Consequently, need of defense strategy that adapts and responds autonomously to these variety of attacks is imperative.

Internet scale DoS attack is a new evolution of conventional flooding DoS attack with the inspiration of shutting down the Internet due to its vulnerable infrastructure. Past DoS attacks directly attacked the victim, usually a single host. Consequently, defences were designed to identify the excessive traffic or filter illegitimate traffic. From the early two thousand, Internet scale DoS attacks started to appear. They aimed to disable highly connected routers or large links with a legitimate action in the form of low-rate traffic or high-rate wanted traffic with protocol messages that are unfiltered by congestion control. The latter can be more devastating due to its global impact therefore attracts the attention of researchers and some applications are now available. The goal of this paper is to introduce Internet scale DoS attack and to survey its theoretical underpinnings and experimental applications.

In this article, we present an in-depth study of the denial of service problem in the Internet, and provide a comprehensive survey of attacks and their countermeasures. We investigate various DoS attack mechanisms, derive a more practical taxonomy of attack mechanisms, and summarize the challenges in DoS defense. View PDF. Save to Library. Create Alert.
