Denial of Service, or DoS, defines the attack to a computer or a network as to deprive users from services. Whether being the attack per se or a component of an attack denial of service basic attack types fall into three categories which are (i) exploitation of computational resources, (ii

Honeypot back-propagation for mitigating spoofing distributed

of network attack. The attack sends appropriate length of packet, while application code could not detect that the length of the packet is out of range, and the operation of inserting header leads to buffer overflow, thereby, this forms denial-of-service attack.

SUMMARY Distributed denial-of-service attacks on public servers have recently become more serious. More are SYN Flood attacks, since the malicious attackers can easily exploit the TCP specification to generate traffic making public servers unavailable. To assure that network services

authentication schemes by making use of the multicast tree as an essential authentication mechanism. Our schemes are efficient and immune to multicast denial-of-service attack. They allow the receivers to immediately authenticate the packets regardless of the packet loss characteristics of the underlying network

forges spurious unpacking behaviors that lead to a denial-of-service attack on host-based generic unpackers. We present the design, implementation, and evaluation of the proposed packer and malware produced using the proposed packer, and show the success of denial-of-service attacks on host-based generic

We consider the problem of overcoming (Distributed) Denial of Service (DoS) attacks by realistic adversaries that have knowledge of their attack's successfulness, e.g., by observing service performance degradation, or by eavesdropping on messages or parts thereof. A solution for this problem

Availability requires that computer systems function normally without loss of resources to legitimate users. One of the most challenging issues to availability is the denial-of-service (DoS) attack. DoS attacks constitute one of the major threats and among the hardest security problems in today’s

Denial-of-service (DoS) detection techniques — such as activity profiling,changepoint detection,and wavelet-based signal analysis — face the considerable challenge of discriminating network-based flooding attacks from sudden increases in legitimate activity or flash events. This survey
