Antonios Gouglidis, Benjamin Green, David Hutchison, Ali Alshawish, more

Energy Informatics > 2018 > 1 > 1 > 1-24

Critical infrastructures – such as electricity networks, power stations and Smart Grids – are increasingly monitored and controlled by computing and communication technologies. The need to address security and protection of electricity infrastructures with a high priority has broadly been recognized. This is driven by many factors, including the rapid evolution of threats and consistent technological...

The Extended Cloud: Review and Analysis of Mobile Edge Computing and Fog From a Security and Resilience Perspective

Syed Noorulhassan Shirazi, Antonios Gouglidis, Arsham Farshad, David Hutchison

IEEE Journal on Selected Areas in Communications > 2017 > 35 > 11 > 2586 - 2595

Mobile edge computing (MEC) and fog are emerging computing models that extend the cloud and its services to the edge of the network. The emergence of both MEC and fog introduce new requirements, which mean their supported deployment models must be investigated. In this paper, we point out the influence and strong impact of the extended cloud (i.e., the MEC and fog) on existing communication and networking...

On the Definition of Access Control Requirements for Grid and Cloud Computing Systems

Antonios Gouglidis, Ioannis Mavridis

Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering > Networks for Grid Applications > General Session 1 > 19-26

The emergence of grid and cloud computing systems has introduced new security concepts, so it requires new access control approaches. Traditional systems engineering processes can be enriched with helper approaches that can facilitate the definition of access control requirements in such complex environments. Looking towards a holistic approach on the definition of access control requirements, we...

2016 8th International Workshop on Resilient Networks Design and Modeling (RNDM) > 196 - 202

2016 8th International Workshop on Resilient Networks Design and Modeling (RNDM)

Utility networks are part of every nation's critical infrastructure, and their protection is now seen as a high priority objective. In this paper, we propose a threat awareness architecture for critical infrastructures, which we believe will raise security awareness and increase resilience in utility networks. We first describe an investigation of trends and threats that may impose security risks...

2016 8th International Workshop on Resilient Networks Design and Modeling (RNDM)

Resilience against disaster scenarios is essential to network operators, not only because of the potential economic impact of a disaster but also because communication networks form the basis of crisis management. COST RECODIS aims at studying measures, rules, techniques and prediction mechanisms for different disaster scenarios. This paper gives an overview of different solutions in the context of...

2016 Resilience Week (RWS) > 140 - 145

2016 Resilience Week (RWS)

Attacks on critical infrastructures' Supervisory Control and Data Acquisition (SCADA) systems are beginning to increase. They are often initiated by highly skilled attackers, who are capable of deploying sophisticated attacks to exfiltrate data or even to cause physical damage. In this paper, we rehearse the rationale for protecting against cyber attacks and evaluate a set of Anomaly Detection (AD)...

Information assurance techniques: Perceived cost effectiveness

Jose M. Such, Antonios Gouglidis, William Knowles, Gaurav Misra, more

Computers & Security > 2016 > 60 > C > 117-133

The assurance technique is a fundamental component of the assurance ecosystem; it is the mechanism by which we assess security to derive a measure of assurance. Despite this importance, the characteristics of these assurance techniques have not been comprehensively explored within academic research from the perspective of industry stakeholders. Here, a framework of 20 “assurance techniques” is defined...

Anomaly Detection in the Cloud Using Data Density

Syed Noorulhassan Shirazi, Steven Simpson, Antonios Gouglidis, Andreas Mauthe, more

2016 IEEE 9th International Conference on Cloud Computing (CLOUD) > 616 - 623

2016 IEEE 9th International Conference on Cloud Computing (CLOUD)

Cloud computing is now extremely popular because of its use of elastic resources to provide optimized, cost-effective and on-demand services. However, clouds may be subject to challenges arising from cyber attacks including DoS and malware, as well as from sheer complexity problems that manifest themselves as anomalies. Anomaly detection techniques are used increasingly to improve the resilience of...

2016 23rd International Conference on Telecommunications (ICT)

Attacks on critical infrastructures are beginning to increase in number and severity. They are often initiated by highly skilled attackers, who are capable of deploying advanced attacks to exfiltrate data or even to cause physical damage. In this paper, we re-visit the rationale for protecting against cyber attacks and propose a framework to monitor, detect and evaluate anomalous behaviour within...

Role-Based Secure Inter-operation and Resource Usage Management in Mobile Grid Systems

Antonios Gouglidis, Ioannis Mavridis

Lecture Notes in Computer Science > Information Security Theory and Practice. Security and Privacy of Mobile Devices in Wireless Communication > Mobile Authentication and Access Control > 38-53

Dynamic inter-domain collaborations and resource sharing comprise two key characteristics of mobile Grid systems. However, inter-domain collaborations have proven to be vulnerable to conflicts that can lead to privilege escalation. These conflicts are detectable in inter-operation policies, and occur due to cross-domain role relationships. In addition, resource sharing requires to be enhanced with...

Security policy verification for multi-domains in cloud systems

Antonios Gouglidis, Ioannis Mavridis, Vincent C. Hu

International Journal of Information Security > 2014 > 13 > 2 > 97-111

The cloud is a modern computing paradigm with the ability to support a business model by providing multi-tenancy, scalability, elasticity, pay as you go and self-provisioning of resources by using broad network access. Yet, cloud systems are mostly bounded to single domains, and collaboration among different cloud systems is an active area of research. Over time, such collaboration schemas are becoming...

2013 IEEE Seventh International Conference on Software Security and Reliability Companion > 35 - 44

2013 IEEE 7th International Conference on Software Security and Reliability-Companion (SERE-C)

The increased complexity of modern access control (AC) systems stems partly from the need to support diverse and multiple administrative domains. Systems engineering is a key technology to manage this complexity since it is capable of assuring that an operational system will adhere to the initial conceptual design and defined requirements. Specifically, the verification stage of an AC system should...

Computers & Security > 2012 > 31 > 4 > 540-556

Modern collaborative systems such as the Grid computing paradigm are capable of providing resource sharing between users and platforms. These collaborations need to be done in a transparent way among the participants of a virtual organization (VO). A VO may consist of hundreds of users and heterogeneous resources. In order to have a successful collaboration, a list of vital importance requirements...
