This work expands on our prior work on an architecture and supporting protocols to efficiently integrate constrained devices into an Information-Centric Network-based Internet of Things in a way that is both secure and scalable. In this work, we propose a scheme for addressing additional threats and integrating trust-based behavioral observations and attribute-based access control by leveraging the capabilities of less constrained coordinating nodes at the network edge close to IoT devices. These coordinating devices have better insight into the behavior of their constituent devices and access to a trusted overall security management cloud service. We leverage two modules, the security manager (SM) and trust manager (TM). The former provides data confidentiality, integrity, authentication, and authorization, while the latter analyzes the nodes' behavior using a trust model factoring in a set of service and network communication attributes. The trust model allows trust to be integrated into the SM's access control policies, allowing access to resources to be restricted to trusted nodes.

MPLS has been in the forefront of high-speed Wide Area Networks (WANs), for almost two decades [1], [12]. The performance advantages in implementing Multi-Protocol Label Switching (MPLS) are mainly its superior speed based on fast label switching and its capability to perform Fast Reroute rapidly when failure(s) occur - in theory under 50 ms [16], [17], which makes MPLS also interesting for real-time applications. We investigate the aforementioned advantages of MPLS by creating two real testbeds using actual routers that commercial Internet Service Providers (ISPs) use, one with a ring and one with a partial mesh architecture. In those two testbeds we compare the performance of MPLS channels versus normal routing, both using the Open Shortest Path First (OSPF) routing protocol. The speed of the Fast Reroute mechanism for MPLS when failures are occurring is investigated. Firstly, baseline experiments are performed consisting of MPLS versus normal routing. Results are evaluated and compared using both single and dual failure scenarios within the two architectures. Our results confirm recovery times within 50 ms.

Security is a key component of the network. Software Defined Networking (SDN) is a refined form of traditional network management system. It is a new encouraging approach to design-build and manage networks. SDN decouples control plane (software-based router) and data plane (software-based switch), hence it is programmable. Consequently, it facilitates implementation of security based applications for the prevention of DOS attacks. Various solutions have been proposed by researches for handling of DOS attacks in SDN. However, these solutions are very limited in scope, complex, time consuming and change resistant. In this article, we have proposed a novel model driven framework i.e. MDAP (Model Based DOS Attacks Prevention) Framework. Particularly, a meta model is proposed. As tool support, a tree editor and a Sirius based graphical modeling tool with drag drop palette have been developed in Oboe designer community edition. The tool support allows modeling and visualization of simple and complex network topology scenarios. A Model to Text transformation engine has also been made part of framework that generates java code for the Floodlight SDN controller from the modeled scenario. The validity of proposed framework has been demonstrated via case study. The results prove that the proposed framework can effectively handle DOS attacks in SDN with simplicity as per the true essence of MDSE and can be reliably used for the automation of security based applications in order to deny DOS attacks in SDN.

Deception technology is a useful approach to improve the security posture of IoT systems. The deployment of replication techniques as a deception tactic is presented with a summary of our research progress towards quantifying the defensive improvement as part of overall risk management considerations.

Nowadays citizens live in a world where communication technologies offer opportunities for new interactions between people and society. Clearly, e-government is changing the way citizens relate to their government, moving the interaction of physical environment and management towards digital participation. Therefore, it is necessary for e-government to have procedures in place to prevent and lessen the negative impact of an attack or intrusion by third parties. In this research work, he focuses on the implementation of anonymous communication in a proof of concept application called “Delta”, whose function is to allow auctions and offers of products, thus marking the basis for future implementations in e-government services.

The Internet of Things (IoT) is a concept that allows the networking of various objects of everyday life and communications on the Internet without human interaction. The IoT consists of Low-Power and Lossy Networks (LLN) which for routing use a special protocol called Routing over Low-Power and Lossy Networks (RPL). Due to the resource-constrained nature of RPL networks, they may be exposed to a variety of internal attacks. Neighbor attack and DIS attack are the specific internal attacks at this protocol. This paper presents an anomaly-based lightweight Intrusion Detection System (IDS) based on threshold values for detecting attacks on the RPL protocol. The results of the simulation using Cooja show that the proposed model has a very high True Positive Rate (TPR) and in some cases, it can be 100%, while the False Positive Rate (FPR) is very low. The results show that the proposed model is fully effective in detecting attacks and applicable to large-scale networks.

Internet of Things is gaining research attention as one of the important fields that will affect our daily life vastly. Today, around us this revolutionary technology is growing and evolving day by day. This technology offers certain benefits like automatic processing, improved logistics and device communication that would help us to improve our social life, health, living standards and infrastructure. However, due to their simple architecture and presence on wide variety of fields they pose serious concern to security. Due to the low end architecture there are many security issues associated with IoT network devices. In this paper, we try to address the security issue by proposing JavaScript sandbox as a method to execute IoT program. Using this sandbox we also implement the strategy to control the execution of the sandbox while the program is being executed on it.

The state of network security today is quite abysmal. Security breaches and downtime of critical infrastructures continue to be the norm rather than the exception, despite the dramatic rise in spending on network security. Attackers today can easily leverage a distributed and programmable infrastructure of compromised machines (or botnets) to launch large-scale and sophisticated attack campaigns. In contrast, the defenders of our critical infrastructures are fundamentally crippled as they rely on fixed capacity, inflexible, and expensive hardware appliances deployed at designated "chokepoints". These primitive defense capabilities force defenders into adopting weak and static security postures configured for simple and known attacks, or otherwise risk user revolt, as they face unpleasant tradeoffs between false positives and false negatives. Unfortunately, attacks can easily evade these defenses; e.g., piggybacking on popular services (e.g., drive-by-downloads) and by overloading the appliances. Continuing along this trajectory means that attackers will always hold the upper hand as defenders are stifled by the inflexible and impotent tools in their arsenal. An overarching goal of my work is to change the dynamics of this attack-defense equation. Instead of taking a conventional approach of developing attack-specific defenses, I argue that we can leverage recent trends in software-defined networking and network functions virtualization to better empower defenders with the right tools and abstractions to tackle the constantly evolving attack landscape. To this end, I envision a new software-defined approach to network security, where we can rapidly develop and deploy novel in-depth defenses and dynamically customize the network's security posture to the current operating context. In this talk, I will give an overview of our recent work on the basic building blocks to enable this vision as well as some early security capabilities we have developed. Using anecdotes from this specific exercise, I will also try to highlight lessons and experiences in the overall research process (e.g., how to pick and formulate problems, the role of serendipity, and the benefits of finding ``bridges'' to other subdomains).

The term Cloud Computing is not something that appeared overnight, it may come from the time when computer system remotely accessed the applications and services. Cloud computing is Ubiquitous technology and receiving a huge attention in the scientific and industrial community. Cloud computing is ubiquitous, next generation's in-formation technology architecture which offers on-demand access to the network. It is dynamic, virtualized, scalable and pay per use model over internet. In a cloud computing environment, a cloud service provider offers “house of resources” includes applications, data, runtime, middleware, operating system, virtualization, servers, data storage and sharing and networking and tries to take up most of the overhead of client. Cloud computing offers lots of benefits, but the journey of the cloud is not very easy. It has several pitfalls along the road because most of the services are outsourced to third parties with added enough level of risk. Cloud computing is suffering from several issues and one of the most significant is Security, privacy, service availability, confidentiality, integrity, authentication, and compliance. Security is a shared responsibility of both client and service provider and we believe security must be information centric, adaptive, proactive and built in. Cloud computing and its security are emerging study area nowadays. In this paper, we are discussing about data security in cloud at the service provider end and proposing a network storage architecture of data which make sure availability, reliability, scalability and security.

Mobile ad-hoc networks are a new field in networking because it works as an autonomous network. Application of mobile ad-hoc networks are increasing day by day in recent year now a days. So it important is increasing to provide suitable routing protocol and security from attacker. Mobile ad-hoc network now a days faces many problems such as small bandwidth, energy, security, limited computational and high mobility. The main problem in mobile ad-hoc networks is that wireless networks, Infrastructure wireless networks have larger bandwidth, larger memory, power backup and different routing protocol easily applies. But in case of mobile ad-hoc networks some of these application failed due to mobility and small power backup so it is required such type of routing protocol which is take small energy during the transfer of packet. So we see that still there are many challenging works in mobile ad-hoc networks remained and to research in this area related to routing protocol, security issues, solving energy problem and many more which is feasible to it. Our research most probably will be dedicated to Authentication in mobile ad-hoc network.

Moving target defense is an area of network security research in which machines are moved logically around a network in order to avoid detection. This is done by leveraging the immense size of the IPv6 address space and the statistical improbability of two machines selecting the same IPv6 address. This defensive technique forces a malicious actor to focus on the reconnaissance phase of their attack rather than focusing only on finding holes in a machine's static defenses. We have a current implementation of an IPv6 moving target defense entitled MT6D, which works well although is limited to functioning in a peer to peer scenario. As we push our research forward into client server networks, we must discover what the limits are in reference to the client server ratio. In our current implementation of a simple UDP echo server that binds large numbers of IPv6 addresses to the ethernet interface, we discover limits in both the number of addresses that we can successfully bind to an interface and the speed at which UDP requests can be successfully handled across a large number of bound interfaces.

This research focuses on hyper visor security from holistic perspective. It centers on hyper visor architecture - the organization of the various subsystems which collectively compromise a virtualization platform. It holds that the path to a secure hyper visor begins with a big-picture focus on architecture. Unfortunately, little research has been conducted with this perspective. This study investigates the impact of monolithic and micro kernel hyper visor architectures on the size and scope of the attack surface. Six architectural features are compared: management API, monitoring interface, hyper calls, interrupts, networking, and I/O. These subsystems are core hyper visor components which could be used as attack vectors. Specific examples and three leading hyper visor platforms are referenced (ESXi for monolithic architecture; Xen and Hyper-V for micro architecture). The results describe the relative strengths and vulnerabilities of both types of architectures. It is concluded that neither design is more secure, since both incorporate security tradeoffs in core processes.
