Cloud computing (CC) is the next revolution in the Information and Communication Technology arena. CC is often provided as a service comparable to utility services such as electricity, water, and telecommunications. Cloud service providers (CSP) offers tailored CC services which are delivered as subscription-based services, in which customers pay based on the usage. Many organizations and servi...

Software Defined Network (SDN) is a new architecture for network management and its main concept is centralizing network management in the network control level that has an overview of the network and determines the forwarding rules for switches and routers (the data level). Although this centralized control is the main advantage of SDN, it is also a single point of failure. If this main contro...

In this paper, we propose a simple but robust scheme to detect denial of service attacks (including distributed denial of service attacks) by monitoring the increase of new IP addresses. Unlike previous proposals for bandwidth attack detection schemes which are based on monitoring the traffic volume, our scheme is very effective for highly distributed denial of service attacks. Our scheme explo...

Attacks on a set of agents with cooperative and antagonistic interactions attempting to achieve linear bipartite consensus are considered here. In consensus, two clusters formed, in each cluster converging final state which is negative the other cluster's state. The adversary seeks slow down by Denial Service (DoS) type attack where attacker has capability break specific number links at time in...

-In this paper, we present a specification and verification method for preventing denial of service in absence of failures and of integrity violations. We introduce the notion of “user agreements” and argue that lack of specifications for these arguments and for simultaneity conditions makes it impossible to demonstrate denial-of-service prevention, in spite of demonstrably fair service access....

This paper presents the results of a case study to the feasibility of introducing ATM SVCs into the Dutch SURFnet research ATM network. The key issue that is examined are the implications of the Quality of Service support of ATM. QoS guarantees for a connection require a portion of the finite ATM network resource. Once all network resource is allocated to connections no new connections will be ...
