Purpose The purpose of this paper is to present an integrative framework for handling the security and usability conflicts during the system development lifecycle. The framework has been formulated while considering key concerns raised after conducting a series of interviews with practitioners from the industry. The framework is aimed at assisting system designers and developers in making reasonably accurate choices when it comes to the trade-offs between security and usability. The outcomes of using the framework are documented as design patterns, which are disseminated among the community of system designers and developers for use in other but similar contexts. Design/methodology/approach A design science research approach was used to develop the integrative framework for usable security. Interviews were conducted for identification of the key concerns; however, the framework was validated during a workshop. Moreover, to validate the patterns’ template and the usable security pattern identified after instantiating the framework, a survey instrument was used. Findings It is important to consider the usability aspect in the development of security systems; otherwise, the systems, despite being secure against attacks, would be susceptible to user mistakes leading to compromises. It is worthwhile to handle usable security concerns right from the start of system development life cycle. Design patterns can help the developers in assessing the usability of their security options. Practical implications Practical implications The framework would assist the designers and developers in handling the security and usability conflicts right from the start of the system development life cycle. The patterns documented after using the framework would help not only the designers and developers working in the industry but also freelancers. Originality/value The authors present a novel framework to handle the security and usability conflicts during the system development life cycle. The development process of the framework was driven by the concerns raised after a series of interviews with the practitioners from industry. The framework presented in this paper was validated during a workshop in which it was exposed for review and comments by the participants from the industry. To demonstrate the use of patterns in general and the framework in particular, a case study featuring smart grids from the domain of cyber-physical systems is presented, which (to the best of the authors’ knowledge) features the first work relevant to usable security in the domain of cyber-physical systems.

At present, an increasing number of researchers and specialists in the construction industry come to the opinion that it is advisable to use a number of technologies (BIM, Smart City, Big Data, IOT and others) in the practice of construction (in the broad sense of this concept), which are united by the concept of the Fourth Industrial Revolution. The result of the implementation of these technologies in the construction should be the transition to the widespread use of cyber-physical systems. The problem of using information technologies in construction today is not due to the lack of this process as such, but to the lack of consistency and consistency in it. Fragmentary nature of the application, inconsistency of the applied technologies at different levels of management and at different stages of the life cycle of construction projects sharply reduce the potential positive effect of informatization and building automation. At the same time, the concept of cyber-physical systems, that is, the integration at the system level of physical processes and controls has proven effective in industrial production. The approaches to ensuring the processes of designing cyber-physical building systems through the development and application of General mathematical models for the processes of data exchange and management are considered. The presented models of data exchange and management of cyber-physical building systems describe the processes implemented at each stage of the life cycle of cyber-physical building systems. Functional blocks of the considered models allow to describe the processes of data collection, storage and processing on the current and past stages of the life cycle of cyber-physical construction systems. The presented models are the elements of mathematical support of the processes of designing cyber-physical building systems, which determine the processes of information exchange and management between the structures of cyber-physical building systems of different levels of hierarchy in the full life cycle.

Cyber-Physical Systems (CPS) will revolutionize how humans relate with the physical world around us. Many grand challenges await the economically vital domains of transportation, health-care, manufacturing, agriculture, energy, defence, aerospace and buildings. Exploration of these potentialities around space and time would create applications which would affect societal and economic benefit. This paper looks into the concept of emerging Cyber-Physical system, applications and security issues in sustaining development in various economic sectors; outlining a set of strategic Research and Development opportunities that should be accosted, so as to allow upgraded CPS to attain their potential and provide a wide range of societal advantages in the future.

The recent proliferation of embedded cyber components in modern physical systems [1] has generated a variety of new security risks which threaten not only cyberspace, but our physical environment as well. Whereas earlier security threats resided primarily in cyberspace, the increasing marriage of digital technology with mechanical systems in cyber-physical systems (CPS), suggests the need for more advanced generalized CPS security measures. To address this problem, in this paper we consider the first step toward an improved security model: detecting the security attack. Using logical truth tables, we have developed a generalized algorithm for intrusion detection in CPS for systems which can be defined over discrete set of valued states. Additionally, a robustness algorithm is given which determines the level of security of a discrete-valued CPS against varying combinations of multiple signal alterations. These algorithms, when coupled with encryption keys which disallow multiple signal alteration, provide for a generalized security methodology for both cyber-security and cyber-physical systems.
