Ariadne: topology aware adaptive security for cyber-physical systems
This paper presents Ariadne, a tool for engineering
topology aware adaptive security for cyber-physical systems. It
allows security software engineers to model security requirements
together with the topology of the operational environment. This
model is then used at runtime to perform speculative threat anal-
ysis to reason about the consequences that topological changes
arising from the movement of agents and assets can have on the
satisfaction of security requirements. Our tool also identifies an
adaptation strategy that applies security controls when necessary
to prevent potential security requirements violations
No digital citizens without digital humanism
Using a Digital Humanism viewpoint when teaching informatics is the key to face the challenges posed to our society by digital technologies. This is particularly relevant for education in school, where children are going to learn about the basic principles and concepts of the discipline. Considering the potential of digital machines and the advancement of the generative artificial intelligence systems, it is essential that school curricula are aimed at developing the proper attitude toward digital technologies since the early years. This means paying attention to both technical and social elements of the digital systems and preparing teachers for this challenge adequately
Topology Aware Adaptive Security
Adaptive security systems aim to protect valuable assets in the face of changes in their operational environment. They do so by monitoring and analysing this environment, and deploying security functions that satisfy some protection (security, privacy, or forensic) requirements. In this paper, we suggest that a key characteristic for engineering adaptive security is the topology of the operational environment, which represents a physical and/or a digital space - including its structural relationships, such as containment, proximity, and reachability. For adaptive security, topology expresses a rich representation of context that can provide a system with both structural and semantic awareness of important contextual characteristics. These include the location of assets being protected or the proximity of potentially threatening agents that might harm them. Security-related actions, such as the physical movement of an actor from a room to another in a building, may be viewed as topological changes. The detection of a possible undesired topological change (such as an actor possessing a safe’s key entering the room where the safe is located) may lead to the decision to deploy a particular security control to protect the relevant asset. This position paper advocates topology awareness for more effective engineering of adaptive security. By monitoring changes in topology at runtime one can identify new or changing threats and attacks, and deploy adequate security controls accordingly. The paper elaborates on the notion of topology and provides a vision and research agenda on its role for systematically engineering adaptive security systems
