Denial of Service (DoS) attack is one of the major problem in today's Internet. It constitutes the hardest security problems nowadays. Particularly Distributed Denial of Service (DDoS) attack have severe impact. The main aim of a DoS is the disruption of services by attempting to control access to a system or service instead of overthrowing the service itself. Disruption-Tolerant Networks (DTNs...

Denial of service attack is evolving from the network layer to the application layer in recent years. Their characteristics show that attack in the application layer is more secret with less data traffic compared with that in the network layer, and it’s more difficult to defend this kind of attack, so we propose the model of application-oriented detection for denial of service attack which invo...

VANET (Vehicular Ad-hoc Network) which is a hy- brid network (combination of infrastructure and infra- structure-less networks) is an emergent technology with promising future as well as great challenges especially in security. By the other hand this type of network is very sensible to safety problem. This paper focuses on a new mechanism for DoS (denial of service) attacks on the physical and ...

Today, Internet has become the primary source of communication in networks. The attack on its infrastructure poses a great challenge in its expansion. Distributed Denial of Service attack is a serious security threat encountered during the past decade. The goal of the attacker is to spoof the source of IP address to hide its source. Various IP traceback schemes such as Probabilistic Packet Mark...

Majority of the network host today are threatened by the network attacks like Denial-of-service(DoS) attack, Distributed DoS(DDoS) attack. The path identification scheme described in this paper can trace back an individual packet back to its source. The routers along the path of the packet mark the packet based on deterministic marking scheme with effective storage requirement by using hash bas...

Distributed Denial-of-Service attacks are an effective means to make a service unavailable, mask other attack activities and generally degrade or disrupt network functionality. The key characteristic is that analysis of and defence against this attack type is difficult because of the high number of attacking hosts and large amount of attack traffic that can be generated. The emerging Peer-to-Pe...

Distributed denial of service (DDoS) attacks are widely regarded as a major threat to the Internet. A flooding-based DDoS attack is a very common way to attack a victim machine by sending a large amount of malicious traffic. Existing networklevel congestion control mechanisms are inadequate in preventing service quality from deteriorating because of these attacks. Although a number of technique...

Domain Name System (DNS) amplification attack is a sophisticated Distributed Denial of Service (DDoS) attack by sending a huge volume of DNS name lookup requests to open DNS servers with the source address spoofed as a victim host. However, from the point of view of an individual network resource such as DNS server and switch, it is not easy to mitigate such attacks because a distributed attack...

The Service-Oriented Computing paradigm enables the construction of distributed systems by assembling loosely coupled pieces of software called services, which have clear interfaces to their functionalities. Service interface descriptions have many aspects, such as complexity and quality, all of which can be measured. This paper presents empirical evidence showing that services interfaces maint...

Denial-of-Service attack is an attempt to make a system, machine or network resources unavailable to its user by blocking or denying the services. The Denial-of-Service attack is identified with the help of detection algorithm. The anomaly detection mechanism not provides the better results so the user need to implement the hybrid detection algorithm which is the combination of anomaly detectio...
