  • Towards a Dynamic Policy Enhanced Integrated Security Architecture for SDN Infrastructure
    NOMS 2020 - 2020 IEEE IFIP Network Operations and Management Symposium, 2020
    Co-Authors: Kallol Krishna Karmakar, Udaya Tupakula, Vijay Varadharajan, Michael Hitchens
    Abstract:

    Enterprise networks are increasingly moving towards Software Defined Networking, which is becoming a major trend in the networking arena. With the increased popularity of SDN, there is a greater need for Security measures for protecting the enterprise networks. This paper focuses on the design and implementation of an Integrated Security architecture for SDN based enterprise networks. The Integrated Security architecture uses a policy-based approach to coordinate different Security mechanisms to detect and counteract a range of Security attacks in the SDN. A distinguishing characteristic of the proposed architecture is its ability to deal with dynamic changes in the Security attacks as well as changes in trust associated with the network devices in the infrastructure. The adaptability of the proposed architecture to dynamic changes is achieved by having feedback between the various Security components/mechanisms in the architecture and managing them using a dynamic policy framework. The paper describes the prototype implementation of the proposed architecture and presents Security and performance analysis for different attack scenarios. We believe that the proposed Integrated Security architecture provides a significant step towards achieving a secure SDN for enterprises.

  • On the Design and Implementation of an Integrated Security Architecture for Cloud with Improved Resilience
    IEEE Transactions on Cloud Computing, 2017
    Co-Authors: Vijay Varadharajan, Udaya Tupakula
    Abstract:

    In this paper, we propose an Integrated Security architecture which combines policy based access control with intrusion detection techniques and trusted computing technologies for securing distributed applications running on virtualised systems. Our Security architecture incorporates access control Security policies for secure interactions between applications and virtual machines in different physical virtualized servers. It provides intrusion detection and trusted attestation techniques to detect and counteract dynamic attacks in an efficient manner. We demonstrate how this Integrated Security architecture is used to secure the life cycle of virtual machines including dynamic hosting and allocation of resources as well as migration of virtual machines across different physical servers. We discuss the implementation of the developed architecture and show how the architecture can counteract attack scenarios involving malicious users exploiting vulnerabilities to achieve privilege escalation and then using the compromised machines to generate further attacks. The feedback between the various Security components of our Security architecture plays a critical role in detecting sophisticated, dynamically changing attacks, thereby increasing the resilience of the overall secure system.

  • Trustcom/BigDataSE/ISPA - Integrated Security for Services Hosted in Virtual Environments
    2016 IEEE Trustcom BigDataSE ISPA, 2016
    Co-Authors: Dilshan Jayarathna, Vijay Varadharajan, Udaya Tupakula
    Abstract:

    In this paper, we introduce an Integrated Security architecture that combines TPM based trust management with hypervisor level access control and intrusion detection system to provide a holistic approach for securing services hosted in virtualised environments. We describe the implementation of the Security architecture in detail and demonstrate the functionality of the proposed architecture for different attack scenarios. Our architecture is able to perform dynamic attack detection and update the Security policies to protect the services from the identified threats. The proposed Integrated Security architecture can be easily adopted to be used in cloud and distributed virtualised environments.

For this reason it is necessary to design and realize highly Integrated, efficient and reliable Security systems. The authors illustrate the work made to design and realize the Integrated Security system of the Senate of the Italian Republic.)

  • ICCST - An Internet of Everything based Integrated Security system for smart archaeological areas
    2016 IEEE International Carnahan Conference on Security Technology (ICCST), 2016

    Abstract:

    The purpose of this paper is to illustrate an Internet of Everything based Integrated Security system for archaeological areas capable of ensuring visitors Security, cultural heritage preservation/protection and great usability for visitors, with particular reference to visitors with disabilities. Genetic Algorithms (GAs) have been used to design the Integrated Security system, in particular for fields elements such as Wi-Fi Access Points, CCTV cameras, installation poles (to respect the archaeological vincula of the site) to ensure a reduction of final costs and a high level of reliability and resilience of the system itself, keeping, into consideration, the typical vincula and restrictions of archaeological areas The proposed system, together with the GAs based optimization technique, thanks to its flexibility, can be used in any kind of archaeological area or any kind of cultural site by means of a proper adaption.
