    How Resilient Are Our Societies? Analyses, Models, and Preliminary Results

    Full text link
    Traditional social organizations such as those for the management of healthcare and civil defence are the result of designs and realizations that matched well with an operational context considerably different from the one we are experiencing today: A simpler world, characterized by a greater amount of resources to match less users producing lower peaks of requests. The new context reveals all the fragility of our societies: unmanageability is just around the corner unless we do not complement the "old recipes" with smarter forms of social organization. Here we analyze this problem and propose a refinement to our fractal social organizations as a model for resilient cyber-physical societies. Evidence to our claims is provided by simulating our model in terms of multi-agent systems.Comment: Paper submitted for publication in the Proc. of SERENE 2015 (http://serene.disim.univaq.it/2015/

    Federated Embedded Systems – a review of the literature in related fields

    This report is concerned with the vision of smart interconnected objects, a vision that has attracted much attention lately. In this paper, embedded, interconnected, open, and heterogeneous control systems are in focus, formally referred to as Federated Embedded Systems. To place FES into a context, a review of some related research directions is presented. This review includes such concepts as systems of systems, cyber-physical systems, ubiquitous computing, internet of things, and multi-agent systems. Interestingly, the reviewed fields seem to overlap with each other in an increasing number of ways

    Cybersecurity: mapping the ethical terrain

    This edited collection examines the ethical trade-offs involved in cybersecurity: between security and privacy; individual rights and the good of a society; and between the types of burdens placed on particular groups in order to protect others. Foreword Governments and society are increasingly reliant on cyber systems. Yet the more reliant we are upon cyber systems, the more vulnerable we are to serious harm should these systems be attacked or used in an attack. This problem of reliance and vulnerability is driving a concern with securing cyberspace. For example, a ‘cybersecurity’ team now forms part of the US Secret Service. Its job is to respond to cyber-attacks in specific environments such as elevators in a building that hosts politically vulnerable individuals, for example, state representatives. Cybersecurity aims to protect cyberinfrastructure from cyber-attacks; the concerning aspect of the threat from cyber-attack is the potential for serious harm that damage to cyber-infrastructure presents to resources and people. These types of threats to cybersecurity might simply target information and communication systems: a distributed denial of service (DDoS) attack on a government website does not harm a website in any direct way, but prevents its normal use by stifling the ability of users to connect to the site. Alternatively, cyber-attacks might disrupt physical devices or resources, such as the Stuxnet virus, which caused the malfunction and destruction of Iranian nuclear centrifuges. Cyber-attacks might also enhance activities that are enabled through cyberspace, such as the use of online media by extremists to recruit members and promote radicalisation. Cyber-attacks are diverse: as a result, cybersecurity requires a comparable diversity of approaches. Cyber-attacks can have powerful impacts on people’s lives, and so—in liberal democratic societies at least—governments have a duty to ensure cybersecurity in order to protect the inhabitants within their own jurisdiction and, arguably, the people of other nations. But, as recent events following the revelations of Edward Snowden have demonstrated, there is a risk that the governmental pursuit of cybersecurity might overstep the mark and subvert fundamental privacy rights. Popular comment on these episodes advocates transparency of government processes, yet given that cybersecurity risks represent major challenges to national security, it is unlikely that simple transparency will suffice. Managing the risks of cybersecurity involves trade-offs: between security and privacy; individual rights and the good of a society; and types of burdens placed on particular groups in order to protect others. These trade-offs are often ethical trade-offs, involving questions of how we act, what values we should aim to promote, and what means of anticipating and responding to the risks are reasonably—and publicly—justifiable. This Occasional Paper (prepared for the National Security College) provides a brief conceptual analysis of cybersecurity, demonstrates the relevance of ethics to cybersecurity and outlines various ways in which to approach ethical decision-making when responding to cyber-attacks

    Improving healthcare through human city interaction

    Get PDF
    The study of information technology has given insufficient focus to a) the structural factors and b) the community perspective. As information systems become increasingly integrated with human systems these wider influences are more important than ever. Human city interaction concepts including their interplay with cyber-physical systems and social computing are appropriated to healthcare. Through Structuration Theory, insights are given into how healthcare through the human city interaction lens can most effectively be improved
