Denial of Service Attacks in MANETs
Denial of service (DoS) attacks are one problem threatening the networks in the Internet of Battle Things (IoBT) world. Since devices move often in this world, the type of network most commonly used in the IoBT world is the Mobile Ad hoc Network (MANET), which dynamically re-configures itself to …

Centralized prevention of denial of service attacks
… e-commerce, and many other essential services. As such, the Internet has become an integral part of the workings of society at large. This has lead to an increased vulnerability to remotely controlled disruption of vital commercial and government operations---with obvious implications. …

On mitigating distributed denial of service attacks
Denial of service (DoS) attacks and distributed denial of service (DDoS) attacks are probably the most ferocious threats in the Internet, resulting in tremendous economic and social implications/impacts on our daily lives that are increasingly depending on the wellbeing of the Internet. How to …

Hop integrity: a defense against denial-of-service attacks
… following three conditions hold for every pair of adjacent routers p and q in the network. First, p does not forward any message to q if q has not been up and reachable. Second, when q receives a message m supposedly from p, then q can check that m was not modified after it was sent. Third, when …

PACKET FILTER APPROACH TO DETECT DENIAL OF SERVICE ATTACKS
<p>Denial of service attacks (DoS) are a common threat to many online services. These attacks aim to overcome the availability of an online service with massive traffic from multiple sources. By spoofing legitimate users, an attacker floods a target system with a high quantity of packets or …

Distributing network identity to mitigate denial-of-service attacks
The CONTRA. Camouflage of Network Traffic to Resist Attacks, project was carried out by Draper Laboratory to provide a defense mechanism against distributed denial of service (DDoS) attacks to both prevent DDoS attacks and mitigate their effects. This Masters project looks at the CONTRA system and …

Denial-of-Service Attacks on Battery-Powered Mobile Computers
A Denial of Service (DoS) attack is an incident in which the user is deprived of the services of a resource he is expected to have. With the increasing reliance on mobile devices like laptops and palmtops, a new type of DoS attack is possible that attacks the batteries of these devices, called …

Mitigating Network-Based Denial-of-Service Attacks with Client Puzzles
Over the past few years, denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks have become more of a threat than ever. These attacks are aimed at denying or degrading service for a legitimate user by any means necessary. The need to propose and research novel methods to mitigate …

Using network management systems to detect Distributed Denial of Service Attacks
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 …

Detection of denial-of-service attacks based on computer vision techniques
A Denial-of-Service (DoS) attack is an intrusive attempt, which aims to force a designated resource (e.g., network bandwidth, processor time or memory) to be unavailable to its intended users. This attack is launched either by deliberately exploiting system vulnerabilities of a victim (e.g., a …

Understanding and Hardening Blockchain Network Security Against Denial of Service Attacks
<p>This thesis aims to examine the security of a blockchain's communication network. A blockchain relies on a communication network to deliver transactions. Understanding and hardening the security of the communication network against Denial-of-Service (DoS) attacks are thus critical to the …

DETECTING DISTRIBUTED DENIAL OF SERVICE ATTACKS IN IPV6 BY USING ARTIFICIAL INTELLIGENCE TECHNIQUES
ABSTRACT The fast growth of the Internet usage has caused problem on Internet protocol address space. To solve this problem, Internet Protocol version 6 (IPv6) was created to expand the availability of address spaces. An important part of the IPv6 suites is the Neighbour Discovery Protocol (NDP), …

Flow-oriented anomaly-based detection of denial of service attacks with flow-control-assisted mitigation
Flooding-based distributed denial-of-service (DDoS) attacks present a serious and major threat to the targeted enterprises and hosts. Current protection technologies are still largely inadequate in mitigating such attacks, especially if they are large-scale. In this doctoral dissertation, the …

Examining key mobility resources through denial of service attacks on proposed global name resolution services
… architecture design that may open it up to denial of service (DoS) attacks and to expose the tradeoffs in mitigating those DoS opportunities. We take as our candidate network architecture design the Future Internet Architecture project MobilityFirst. MobilityFirst's overarching goal, driven …

A comprehensive study of distributed denial of service attack with the detection techniques
Today, net related net services are indivisible in our life. Therefore, for the success of certain types of organizations, some sustained simplification of services is essential. However, these service area units were usually hindered by the constant threat from numerous kinds of attacks. One such …

Mitigating Network Service Disruptions in High-bandwidth, Intermittently Connected, and Peer-to-Peer Networks
… high-bandwidth, ubiquitous and low-cost network services. This demand has pushed ISPs and application providers to offer more bandwidth, allow users to access the Internet almost everywhere, and provide cheap or free network services using peer-to-peer networks. These three trends underlie the …

Design and Analysis of Anomaly Detection and Mitigation Schemes for Distributed Denial of Service Attacks in Software Defined Network. An Investigation into the Security Vulnerabilities of Software Defined Network and the Design of Efficient Detection and Mitigation Techniques for DDoS Attack using Machine Learning Techniques
Software Defined Networks (SDN) has created great potential and hope to overcome the need for secure, reliable and well managed next generation networks to drive effective service delivery on the go and meet the demand for high data rate and seamless connectivity expected by users. Thus, it is a …
