About this product: 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 denial-of-service attack, a pervasive and growing threat to the Internet. What do you do? Internet Denial of Service sheds light on a complex and fascinating form of computer attack that impacts the confidentiality, integrity, and availability of millions of computers worldwide. It tells the network administrator, corporate CTO, incident responder, and student how DDoS attacks are prepared and executed, how to think about DDoS, and how to arrange computer and network defenses. It also provides a suite of actions that can be taken before, during, and after an attack.Inside, you'll find comprehensive information on the following topics *How denial-of-service attacks are waged *How to improve your network's resilience to denial-of-service attacks *What to do when you are involved in a denial-of-service attack *The laws that apply to these attacks and their implications *How often denial-of-service attacks occur, how strong they are, and the kinds of damage they can cause *Real examples of denial-of-service attacks as experienced by the attacker, victim, and unwitting accomplices The authors' extensive experience in handling denial-of-service attacks and researching defense approaches is laid out clearly in practical, detailed terms.
About this product: Distributed Denial of Service (DDoS) attacks are attempts to overwhelm a computer system in order to deny access by legitimate users. They are generally unstoppable, but there is a good deal of on-going research on methods to reduce their negative effects. This paper will deal with the design of a model that simulates such an attack. The simulation model is then used to study possible ways to defend against these attacks. Three experiments are run: 1) using a priority queue to sort messages from clients based on how many connections they have open on the server; 2) limiting the number of connections each client can create; and 3) having the server forcefully delete the oldest established connection, whenever its connection table becomes full. Results show that method 1 is totally ineffective while method 2 somewhat improves the overall performance of the system. However, method 3, combined with method 2, produces significantly improved performance against a DDoS attack.

Description: We analyze a problem in computer network security, wherein packet filters are deployed to defend a network against spoofed denial of service attacks. Information on the Internet is transmitted by the exchange of IP packets, which must declare their origin and destination addresses. A route-based packet filter verifies whether the purported origin of a packet is correct with respect to the current route map. We examine the optimization problem of finding a minimum cardinality set of nodes to filter in the network such that no spoofed packet can reach its destination. We prove that this problem is NP-hard, and derive properties that explicitly relate the filter placement problem to the vertex cover problem. We identify topologies and routing policies for which a polynomial-time solution to the minimum filter placement problem exists, and prove that under certain routing conditions a greedy heuristic for the filter placement problem yields an optimal solution.
About this product: This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A239034. The abstract provided by the Pentagon follows: The Institute of Electrical and Electronics Engineers' new 802.16 standard is set to revolutionize the delivery of Broadband Wireless Access (BWA) , much as the 802.11 "Wi-Fi" standard transformed wireless access to Local Area Networks. The standard describes a set of Medium Access Controls (MAC) and Air Interfaces that cover a broad range of broadcast frequencies and applications. As a result, manufacturers are developing IEEE 802.16 compliant equipment for high speed point-to-point circuits and point-to-multipoint circuits dubbed Wireless Metropolitan Area Networks (WMANs). These networks can span several miles and contain hundreds of subscribers. Shortly after IEEE 802.11 "Wi-Fi" systems became widespread, several serious Denial of Service (DoS) vulnerabilities inherent to the standard were discovered. This thesis examines the MAC layer of the 802.16 standard to determine whether these types of denial of service vulnerabilities are also present in the new standard. Also examined are vulnerabilities that may be unique to the 802.16 standard.

The Storming Media report number is A752793. The abstract provided by the Pentagon follows: Distributed Denial of Service (DDoS) Attacks have been increasingly found to be affecting the normal functioning of organizations causing billions of dollars of losses. Organizations are trying their best to minimize their losses from these systems. However, most of the organizations widely use the Network Management Systems (NMS) to observe and manage their networks. One of the major functional areas of a NMS is Security Management. This thesis examines how the Network Management Systems could aid in the detection of the DDoS attacks so that the losses from these could be minimized. The thesis details the SNMP MIB variables of importance for detecting these attacks and the MIB signatures of the specific attack.

About this product: Mobile ad hoc networks (MANETs) are especially susceptible to a large class of denial-of-service (DoS) attacks due to the limitations of mobile devices and the wireless medium. As a result, quality-of-service (QoS) signaling protocols for MANETs are highly vulnerable to these attacks. This book analyzes a class of DoS attacks on QoS based signaling protocols for MANETs and then proposes a new distributed QoS signaling scheme that is resilient to these DoS attacks. Moreover, this book introduces a quantitative metric for the fairness experienced by a flow in the presence of flooding attacks and develops a model to study the impact of flow aggregation on the fairness experienced by a flow in the presence of flooding attacks. It also considers the problem of allocating bandwidth to a set of traffic flows at a statistical multiplexer to provide both QoS and resistance to the discussed DoS attacks. This book should be especially beneficial to professionals in Communication Networks and Network Security fields, and everyone else interested in learning about robust telecommunication systems.
