whitepaper An Efficient Filter for Denial-of-Service Bandwidth Attacks2008-01-01 University of Melbourne
  This paper presents an efficient method for detecting and filtering denial-of-service bandwidth attacks. The system called TOPS (Tabulated Online Packet Statistics) can monitor a large number of network addresses in a compact, fixed-size structure using several effective heuristics. The paper demonstrates that TOPS can detect bandwidth attacks in a standard benchmark dataset with a high accuracy and a low false alarm rate. A key benefit of TOPS is that it uses few computational resources and does not slow down during an attack.

whitepaper Protection for the Cisco Catalyst 6500 Series Switches Against Denial-of-Service Attacks2007-12-24 Cisco Systems
  Denial-of-Service (DoS) attacks continue to be a serious threat to enterprise and service provider networks. They can disrupt mission-critical services, prevent data transfer between devices, and decrease overall productivity. The Cisco Catalyst 6500 Series Supervisor Engine 32 and Supervisor Engine 720 include hardware-based mechanisms that can effectively protect against DoS attacks on the Cisco Catalyst 6500 Series switches.

whitepaper How Cisco IT Protects Against Distributed Denial of Service Attacks2007-12-17 Cisco Systems
  Cisco IT uses a variety of techniques to protect the Cisco network from DDoS attacks. When the attacks originate from a broad range of spoofed addresses and target mission-critical servers, Cisco often uses Cisco Guard, which provides an added layer of protection. This case study describes Cisco IT's internal use of Cisco Guard within the Cisco global network, a leading-edge enterprise environment that is one of the largest and most complex in the world. Cisco customers can draw on Cisco IT's real-world experience in this area to help support similar enterprise needs.

whitepaper The Early Detection of DDoS Based on the Persistent Increment Feature of the Traffic Volume2007-12-03 Polytechnic University
  One of the major threats to cyber security is Distributed Denial of Service (DDoS) attacks. This paper proposes a new algorithm based on the persistent increment tendency of DDoS traffic. The scheme can detect a DDoS attack in its early stages when the attacking packet's attribute value has no distinct features. It can differentiate DDoS from flash crowd traffic. This scheme detects DDoS attacks with on-line and distributed characteristics. Simulation shows the algorithm's validity and accuracy.   
whitepaper Botnets: The New Threat Landscape2007-12-01 Cisco Systems
  A botnet is an army of compromised machines, also known as "Zombies," that are under the command and control of a single "Botmaster." The rise of consumer broadband has greatly increased the power of botnets to launch crippling Denial of Service (DoS) attacks on servers, infect millions of computers with spyware and other malicious code, steal identity data, send out vast quantities of spam, and engage in click fraud, blackmail, and extortion. Botnets are the primary security threat on the Internet today. It is easy to commission botnet attack services and hackers are quicker than ever to exploit new vulnerabilities. This white paper discusses the typical lifecycle of a botnet, the damage caused by botnet attacks, and the most effective detection and mitigation techniques.

whitepaper Denial of Service Attacks and the Emergence of Intrusion Prevention Systems2007-11-13 tylerAreber.com
  In an age of political unrest and war, the internet is being used as a source of constant communication and even attack. Since 2000, Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks have been prevalent across the internet. These attacks which can be launched from pretty much anywhere, against anyone, have cost private companies and other organizations millions of dollars resulting from downtime. The purpose of this paper is to give an in depth look at what exactly denial of service attacks are, what forms they come in and how they can be stopped. The contents of this paper are based off of the Sans Reading Room white paper Denial of Service attacks and the emergence of Intrusion Prevention Systems.

whitepaper Denial of Service or Denial of Security?: How Attacks on Reliability Can Compromise Anonymity2007-11-02 Association for Computing Machinery
  This paper considers the effect attackers who disrupt anonymous communications have on the security of traditional high- and low-latency anonymous communication systems, as well as on the Hydra-Onion and Cashmere systems that aim to offer reliable mixing, and Salsa, a peer-to-peer anonymous communication network. The paper shows that Denial of Service (DoS) lowers anonymity as messages need to get retransmitted to be delivered, presenting more opportunities for attack. The paper uncovers a fundamental limit on the security of mix networks, showing that they cannot tolerate a majority of nodes being malicious. Cashmere, Hydra-Onion, and Salsa security is also badly affected by DoS attackers. The results are backed by probabilistic modeling and extensive simulations and are of direct applicability to deployed anonymity systems.

whitepaper A Silent SMS Denial of Service (DoS) Attack2007-10-31 University of Pretoria
  Global System for Mobile communications (GSM) is a popular mobile communications network. Short Message Service (SMS) is an easily adopted person-to-person communications technology for mobile devices. The GSM architecture allows for the insertion of mass application-generated SMS messages directly into the network infrastructure. In contrast, a mass continuous send of "Silent" SMS messages constitutes an invisible Denial of Service (DoS) attack on a mobile handset. Such a mobile handset DoS attack may be conducted for economic advantage to elude another party from communicating. This paper describes, from a technical perspective, how a silent application-generated denial of service (DoS) SMS attack is conducted.

whitepaper Improved Detection System of Denial of Service Attack2007-10-17 Institute of Electrical and Electronics Engineers
  A problem with current intrusion detection systems is that they have many false positive and false negative events. Most of the existing Intrusion detection systems implemented nowadays depend on rule-based expert systems where new attacks are not detectable. In this paper, a possible application of Neural Networks is presented as a component of an intrusion detection system.
