The Impact

A Mobile Ad-Hoc Networks (MANET) is widely used in many industrial and people's life applications, such as earth monitoring, natural disaster prevention, agriculture biomedical related applications, and many other areas. Security threat is one of the major aspects of MANET, as it is one of the basic requirements of wireless sensor network, yet this problem has not been sufficiently explored. The main purpose of this paper is to study different MANETs routing protocols with three scenarios of Denial of Service (DoS) attacks on network layer using proactive routing protocol i.e. Optimized Link State Routing (OLSR) and Reactive routing protocols like Ad hoc On-Demand Distance Vector (AODV), Hybrid routing protocols like Geographic Routing Protocol (GRP). Moreover, a comparative analysis of DoS attacks for throughput, Data loss, delay and network load is taken into account. The performance of MANET under the attack is studied to find out which protocol is more vulnerable to the attack and how much is the impact of the attack on both protocols. The simulation is done using OPNET 17.

Концепция программно-конфигурируемых сетей (SDN) стремительно набирает популярность в управлении сетевой инфраструктурой центров обработки данных и операторов связи. К её ключевым функциям относятся мониторинг, детальное управление, гибкость и масштабируемость. Но вместе с тем, централизованное управление SDN делает его уязвимым для различных типов атак, таких как спуфинг и отказ в обслуживании (DoS). DoS-атаки оказывают наиболее серьезное воздействие, поскольку они снижают производительность сети из-за перегрузки ее различных компонентов, то есть контроллера, коммутатора и канала управления. Существующие подходы справляются с DoS-атаками в SDN либо путем отбрасывания вредоносных пакетов, либо путем объединения правил потока, что приводит к потерям легитимного трафика. Для уменьшения последствий DoS-атак в этой статье предлагается использование механизма многоуровневой справедливой очереди, который обеспечивает совместное использование ресурсов контроллера с несколькими уровнями очередей, которые могут динамически расширяться и агрегироваться в зависимости от загруженности сети. Предлагаемый подход оценивается путем сравнения его с базовым контроллером SDN. Результаты моделирования показывают, что предлагаемый подход увеличивает производительность SDN с точки зрения использования пропускной способности канала управления. The concept of Software Defined Networking (SDN) is rapidly gaining popularity in the management of the network infrastructure of data centers and telecom operators. Its key functions include monitoring, granular control, flexibility and scalability. But at the same time, the centralized management of SDN makes it vulnerable to various types of attacks, such as spoofing and denial of service (DoS). DoS attacks have the most serious impact because they degrade network performance by overloading various components such as the controller, switch, and control channel. Existing approaches deal with SDN DoS attacks either by dropping malicious packets or by combining flow rules, which leads to the loss of legitimate traffic. To mitigate the impact of DoS attacks, this article proposes the use of a tiered fair queuing mechanism, which allows the sharing of controller resources with multiple queue tiers that can dynamically expand and aggregate based on network congestion. The proposed approach is evaluated by comparing it to a basic SDN controller. Simulation results show that the proposed approach increases SDN performance in terms of control channel bandwidth utilization.

The Impact

Cloud computing is the fastest growing technology in today's world. Cloud services provide pay as go models on capacity or usage. For providing better cloud services, capacity planning is very important. Proper capacity planning will maximize efficiency and on the other side proper control over the resources will help to overcome from attacks. As the technology develops in one side, threats and vulnerabilities to security also increases on the other side. A complete analysis of Denial of Service (DOS) attacks in cloud computing and how are they done in the cloud environment and the impact of reduced capacity in cloud causes greater significance. Among all the cloud computing attacks, DOS is a major threat to the cloud environment. In this book chapter, we are going to discuss DOS attack in the cloud and its types, what are the tools used to perform DOS attack and how they are detected and prevented. Finally it deals with the measures to protect the cloud services from DOS attack and also penetration testing for DOS attack.

The Impact

Software-defines networkstransfer the control of the entire network to a single autonomous software system. One outcome is the ability to flexibly configure and manage the network, but at the same time it opens up several new attack vectors. As the impact of compromised devices increases significantly, the development of SDN devices must be subject to ongoing threat analysis. A STRIDE-based security analysis of the SDN, presented in this paper, reveals a wide range of SDN-specific threats, which have not yet been counteracted adequately. Some of them are inherently tied to SDN design principles, such as controllers becoming potential central attack targets; others are inherited from the underlying infrastructure, e. g., the susceptibility to Spoofing.Based on the results of this analysis, this article identifies the main threats and proposes solutions that allow the development of a secure SDN architecture. It also emphasizes the role of authenticity and integrity controls for the involved components and the management protocol messages exchanged between them. A key element of the proposed model is to ensure that security measures not only prevent, but also detect attempts and successful attacks on SDN components. It is also worth noting that securing the management communication still has to rely on well-established traditional concepts, such as out-of-band management or at least separate management VLANs. Furthermore, solutions to prevent flow table flooding, e. g., as a result of DoS attacks, will need to be designed and deployed.
