- Protecting Internet Connectivity of Hybrid Ad Hoc Network Gateways
- Denial of Service DoS attacks are a real problem in the Internet today. Future mobile all-IP hybrid ad hoc networks can suffer from the same problems as their fixed network counterparts. However, hybrid ad hoc networks are vulnerable even to small scale DoS attacks. This paper presents two DoS attacks...

- Denial of Service/Distributed Denial of Service
- The Internet has become an indispensable business tool and its availability is often taken for granted. Organisations are increasingly dependent on the Internet through the adoption of email communications and interactive web-based services. However, with dependence comes weakness; the sudden and unexpected loss of Internet access and system function carries...

- dFence: Transparent Network-Based Denial of Service Mitigation
- Denial of Service DoS attacks are a growing threat to the availability of Internet services. The paper presents dFence, a novel network-based defense system for mitigating DoS attacks. The main thesis of dFence is complete transparency to the existing Internet infrastructure with no software modifications at either routers, or the...

- A Survey on Solutions to Distributed Denial of Service Attacks
- Distributed Denial of Service DDoS attack is a large-scale, coordinated attack on the availability of services of a victim system or network resource, launched indirectly through many compromised computers on the Internet. Researchers have come up with more and more specific solutions to the DDoS problem. However, existing DDoS attack...

- Vanguard: A New Detection Scheme for a Class of TCP-Targeted Denial-of-Service Attacks
- A few low-rates, TCP-targeted Denial-of-Service DoS attacks have been recently proposed, including the Shrew attack, Reduction of Quality RoQ attack, and Pulsing DoS PDoS attack. All of them use periodic attack pulses to throttle TCP flows. These attacks could potentially become major threats to the Internet's stability and therefore they...

- Countering DNS Security Threats
- As I'm sure you know, your DNS server is one of the mostcritical components in your network infrastructure. Your DNS server is not onlynecessary for resolving Internet domain names, but Active Directory absolutelycannot function without it. That being the case, it is in your best interest toprotect your DNS server...

- Denial-of-Service & Distributed Denial-of-Service on the Internet
- Denial-of-Service and Distributed Denial-of-Service is costing the economy world-wide billions of dollars. The economy is the cornerstone of the society and its collapse will certainly change the way in which humanity exists today. The three main goals of computer security are availability, confidentiality and integrity. The focus of this paper...

- A Divide-and-Conquer Strategy for Thwarting Distributed Denial-of-Service Attacks
- Attack mitigation schemes actively throttle attack traffic generated in Distributed Denial-of-Service DDoS attacks. This paper presents Attack Diagnosis AD, a novel attack mitigation scheme that adopts a divide-and-conquer strategy. AD combines the concepts of Pushback and packet marking, and its architecture is in line with the ideal DDoS attack countermeasure...

- Design and Development of Proactive Models for Mitigating Denial-of-Service and Distributed Denial-of-Service Attacks
- Denial-of-Service DoS attacks, orchestrated by a single host or multiple hosts in a coordinated manner, have become an increasingly frequent disturbance in today's Internet. Generally, attackers launch Distributed Denial-of-Service DDoS attacks by directing a massive number of attack sources to send useless traffic to the victim. The victim's services are...

- A Silent SMS Denial of Service (DoS) Attack
- 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...

- WON (Wireless Overlay Network) for Traceback of Distributed Denial of Service
- This paper presents an incremental and scalable solution for tracing Denial of Service DoS and Distributed DoS DDoS attacks. The approach allows the victim to identify the network paths traversed by attack traffic without requiring the support from ISP or knowledge of the network topology. In contrast to previous probabilistic...

- Measuring Denial of Service
- Denial-of-Service DoS attacks significantly degrade service quality experienced by legitimate users, by introducing large delays, excessive losses, and service interruptions. The main goal of DoS defenses is to neutralize this effect, and to quickly and fully restore quality of various services to levels acceptable by the users. To objectively evaluate...

- Mitigating Denial of Service Attacks: A Tutorial
- This paper describes what Denial of Service DoS attacks are, how they can be carried out in IP networks, and how one can defend against them. Distributed DoS DDoS attacks are included here as a subset of DoS attacks. A DoS attack has two phases: a deployment and an attack...

- A Survey of Bots Used for Distributed Denial of Service Attacks
- Off late one has seen the arrival of Distributed Denial-of-Service DDoS open-source bot-based attack tools facilitating easy code enhancement, and so resulting in attack tools becoming more powerful. Developing new techniques for detecting and responding to the latest DDoS attacks often entails using attack traces to determine attack signatures and...

- Best Practices for Preventing DoS/Denial of Service Attacks
- Many corporate websites have suffered from illegal denial-of-service DoS attacks more than once. The companies that learn how to turn these experiences to their advantage go a long way to ensuring it doesn't happen again. Sometimes there's nothing like adversity to give a new look at surroundings. And the events...

- A Taxonomy for Denial-of-Service Attacks in Wireless Sensor Networks
- Wireless Sensor Networks WSNs are transitioning to real-world applications, where they face attacks already experienced by the Internet and wireless ad hoc networks. One such attack is that of Denial-Of-Service DOS, which is believed will only become more prevalent as sensor networks become more pervasive and accessible. With the inherent...

- A Denial-of-Service Resistant DHT
- This paper considers the problem of designing scalable and robust information systems based on multiple servers that can survive even massive Denial-of-Service DoS attacks. More precisely, the paper focusing on designing a scalable Distributed Hash Table DHT that is robust against so-called past insider attacks. In a past insider attack,...

- Managed Public Key Infrastructure: Securing Your Business Applications
- Distributed Denial of Service DDoS attacks are quite common on the Internet today. They have been known to generate tremendous volumes of traffic to the victims. Often the attack can be thwarted with appropriate countermeasures or filters applied to routers. Recently there has been an increase in the number of...

- Defending Network-Based Services Against Denial of Service Attacks
- Over the last decade, several value-added services have been proposed for deployment in the Internet. IP multicast is an example of such a service. IP multicast is a stateful service in that it requires routers to maintain state for forwarding multicast data toward receivers. This characteristic makes the service and...
