- PublicationInteracting with the Arrowhead Local Cloud: On-boarding Procedure(IEEE, 2018-05)
; ; ;Hegedűs, Csaba; ;Delsing, JerkerEliasson, JensIndustrial automation systems are advancing rapidly and a wide range of standards, communication protocols and platforms supporting the integration of devices are introduced. It is therefore necessary to design and build appropriate tools and frameworks that allow the integration of devices with multiple systems and services. In this work we present the Arrow-head Framework, used to enable collaborative IoT automation and introduce two support core systems, SystemRegistry and DeviceRegistry, which are needed to create a chain of trust from a hardware device to a software system and its associated services. Furthermore, we propose an on-boarding procedure of a new device interacting with the Arrowhead local cloud. This ensures that only valid and authorized devices can host software systems within an Arrowhead local cloud.179Scopus© Citations 27 - PublicationA Lightweight Authentication Mechanism for M2M Communications in Industrial IoT Environment(2019)
;Esfahani, A. ;Mantas, G. ;Matischek, R. ;Saghezchi, F.; ; ; ;Schmittner, Ch.Bastos, J.In the emerging industrial Internet of Things (IIoT) era, machine-to-machine (M2M) communication technology is considered as a key underlying technology for building IIoT environments, where devices (e.g., sensors, actuators, and gateways) are enabled to exchange information with each other in an autonomous way without human intervention. However, most of the existing M2M protocols that can be also used in the IIoT domain provide security mechanisms based on asymmetric cryptography resulting in high computational cost. As a consequence, the resource-constrained IoT devices are not able to support them appropriately and thus, many security issues arise for the IIoT environment. Therefore, lightweight security mechanisms are required for M2M communications in IIoT in order to reach its full potential. As a step toward this direction, in this paper, we propose a lightweight authentication mechanism, based only on hash and XOR operations, for M2M communications in IIoT environment. The proposed mechanism is characterized by low computational cost, communication, and storage overhead, while achieving mutual authentication, session key agreement, device's identity confidentiality, and resistance against the following attacks: replay attack, man-in-the-middle attack, impersonation attack, and modification attack.561 153Scopus© Citations 163 - PublicationTowards Resilience Metrics for Future Cloud Applications(2016)
;Novak, Marko ;Shirazi, Syed Noorulhassan ;Hudic, Aleksandar ;Hecht, Thomas; ;Hutchison, David; An analysis of new technologies can yield insight into the way these technologies will be used. Inevitably, new technologies and their uses are likely to result in new security issues regarding threats, vulnerabilities and attack vectors. In this paper, we investigate and analyse technological and security trends and their potential to become future threats by systematically examining industry reports on existing technologies. Using a cloud computing use case we identify potential resilience metrics that can shed light on the security properties of the system.144Scopus© Citations 3 - PublicationAutomated and Secure Onboarding for System of Systems(IEEE, 2021-08-03)
; ; ; ; ;Péceli, Bálint ;Singler, Gábor ;Kovács, Kristóf; Delsing, JerkerThe Internet of Things (IoT) is rapidly changing the number of connected devices and the way they interact with each other. This increases the need for an automated and secure onboarding procedure for IoT devices, systems and services. Device manufacturers are entering the market with internet connected devices, ranging from small sensors to production devices, which are subject of security threats specific to IoT. The onboarding procedure is required to introduce a new device in a System of Systems (SoS) without compromising the already onboarded devices and the underlying infrastructure. Onboarding is the process of providing access to the network and registering the components for the first time in an IoT/SoS framework, thus creating a chain of trust from the hardware device to its hosted software systems and their provided services. The large number and diversity of device hardware, software systems and running services raises the challenge to establish a generic onboarding procedure. In this paper, we present an automated and secure onboarding procedure for SoS. We have implemented the onboarding procedure in the Eclipse Arrowhead framework. However, it can be easily adapted for other IoT/SoS frameworks that are based on Service-oriented Architecture (SoA) principles. The automated onboarding procedure ensures a secure and trusted communication between the new IoT devices and the Eclipse Arrowhead framework. We show its application in a smart charging use case and perform a security assessment.154Scopus© Citations 4 - PublicationEstablishing a Chain of Trust in a Sporadically Connected Cyber-Physical System(IEEE, 2021-05)
; ; ; ;Stummer, Anna; ; ;Pirker, Dominic ;Schmittner, ChristophDelsing, JerkerDrone based applications have progressed significantly in recent years across many industries, including agriculture. This paper proposes a sporadically connected cyber-physical system for assisting winemakers and minimizing the travel time to remote and poorly connected infrastructures. A set of representative diseases and conditions, which will be monitored by land-bound sensors in combination with multispectral images, is identified. To collect accurate data, a trustworthy and secured communication of the drone with the sensors and the base station should be established. We propose to use an Internet of Things framework for establishing a chain of trust by securely onboarding drones, sensors and base station, and providing self-adaptation support for the use case. Furthermore, we perform a security analysis of the use case for identifying potential threats and security controls that should be in place for mitigating them.126 - PublicationTowards Modelling a Cloud Application's Life Cycle(2016-09)

; ; ; ; ; The fast growing number of cloud based Infrastructure-as-a-Service instances raises the question, how the operations security depending on the underlying cloud computing infrastructure can be sustained and guaranteed. Security standards provide guidelines for information security controls applicable to the provision and use of the cloud services. The objectives of operations security are to support planning and sustaining of day-to-day processes that are critical with respect to security of information environments. In this work we provide a detailed analysis of ISO 27017 standard regarding security controls and investigate how well popular cloud platforms can cater for them. The resulting gap of support for individual security controls is furthermore compared with outcomes of recent cloud security research projects. Hence the contribution is twofold, first we identify a set of topics that still require research and development and secondly, as a practical output, we provide a comparison of popular industrial and open-source platforms focusing on private cloud environments, which are important for Industry 4.0 use cases.203Scopus© Citations 1 - PublicationImpact of Critical Infrastructure Requirements on Service Migration Guidelines to the Cloud(IEEE, 2015)
;Wagner, Christian ;Hudic, Aleksandar; ; Pallas, FrankA high level of information security in critical infrastructure IT systems and services has to be preserved when migrating their IT services to the cloud. Often various legislative and security constraints have to be met in line with best practice guidelines and international standards to perform the migration. To support the critical infrastructure providers in migrating their services to the cloud we are developing a process based migration guideline for critical infrastructure providers focusing on information security. First of all we investigate, via questionnaires, how the importance of individual security topics covered in such guidelines differentiates between industry stakeholders and critical infrastructure providers. This supports the selection of relevant security topics and the considered guidelines and standards, which we survey in search for common relevant security topics. Subsequently we present the analysis of the above-mentioned security requirements and how they affect a here developed taxonomy for a process-based security guideline. Furthermore we present potential service migration use cases and how our methodology would affect the migration of secure critical infrastructure services.149Scopus© Citations 4 - PublicationOn the Cost of Security Compliance in Information Systems(International Institute of Informatics and Systemics, 2019)
; ; ; ;Aldrian, AndreasThe onward development of information and communication technology has led to a new industrial revolution called Industry 4.0. This revolution involves Cyber-Physical Production Systems (CPPS), which consist of intelligent Cyber-Physical Systems that may be able to adapt themselves autonomously in a production environment. At the moment, machines in industrial environments are often not connected to the internet, which thus needs a point-to-point connection to access the device if necessary. Through Industry 4.0, these devices should enable remote access for smart maintenance through a connection to the outside world. However, this connection opens the gate for possible cyber-attacks and thus raises the question about providing security for these environments. Therefore, this paper used an adapted approach based on SixSigma to solve this security problem by investigating security standards. Security requirements were gathered and mapped to controls from well known security standards, formed into a catalog. This catalog includes assessment information to check how secure a solution for a use case is and also includes a link to an estimation method for implementation cost. Thus this paperâs outcome shows how to make Industry 4.0 use cases secure by fulfilling security standard controls and how to estimate the resulting implementation costs.570 107 - PublicationConnected cars â Threats, vulnerabilities and their impact(IEEE, 2018-05)
; ; ;Schmittner, Christoph; ; Delsing, JerkerThe growing demand for interoperability between system components within a connected car has led to new security challenges in automotive development. The existing components, based on established technology, are often being combined to form such a connected car. For such established technologies, individual, often sector specific threat and vulnerability catalogs exist. The aim of this paper is to identify blocks of established technologies in a connected car and to consolidate the corresponding threat and vulnerability catalogs relevant for the individual constituent components. These findings are used to estimate the impact on specific system components and subsystems to identify the most crucial components and threats.212Scopus© Citations 13
