Addressing Cyber Security Accessibility: A Qualitative Study

An architectural systems engineering methodology for addressing cyber security

This paper discusses important shortcomings of current approaches to systems security engineering. The value and limitations of perimeter security designs are examined. An architectural approach to systems security engineering is introduced as a complementary means for strengthening current approaches. Accordingly, this paper outlines a methodology to identify classes of new reusable system sec...

Addressing Safety and Security Contradictions in Cyber-Physical Systems

Modern cyber-physical systems are found in important domains such as automobiles, medical devices, building automation, avionics, etc.. Hence, they are increasingly prone to security violations. Often such vulnerabilities occur as a result of contradictory requirements between the safety/real-time properties and the security needs of the system. In this paper we propose a formal framework that ...

Cyber-Physical Systems Security: a Systematic Mapping Study

Context: Cyber-physical systems (CPS) are integrations of computation, networking, and physical processes. Due to the tight cyberphysical coupling and to the potentially disrupting consequences of failures, security is one of the primary concerns for this type of systems. CPS security is attracting several research efforts from different and independent areas (e.g., secure control, intrusion de...

Cyber Security Countermeasures to Combat Cyber Terrorism

Cyber Security for Cyber Physcial Systems: a Trust-based Approach

CyberPhysical Systems (CPS) consist of a combination of different embedded subsystems, which work independently of each other and also interact with the external environment. Such embedded systems operate in the presence of inherent uncertainty, context dependencies and adversarial certainty arising from both the cyber and physical worlds. Security is one of the key concepts to shield the CPS e...
