Encyclopedia of Quantitative Risk Analysis and Assessment - Cyber Risk Management
Wiley StatsRef: Statistics Reference Online, 2008Co-Authors: James WallnerAbstract:In most modern information systems (IS) and process control systems (PCS), functionality and security are Competing Design goals. Therefore, system Designers and operators are constantly forced to make security-related trade-off decisions. To reach the right balance between functionality and security, systems security engineers and network operators have to build information and process control systems that are secure against real-world cyber attacks without overengineering against any particular one. By understanding which cyber attacks are most likely and which risks are most serious, system Designers and operators can make informed security-related trade-off decisions. Cyber risk management is the process of studying the threats, vulnerabilities, and mission impacts of cyber attacks that provides the appropriate metric for trading off between the Competing Design goals of security and functionality of information and process control systems. Keywords: cyber risk management; security-related trade-off; cyber attack; mission impact; threat; vulnerability; countermeasure; attack space; expected loss

risk based systems security engineering stopping attacks with intention
IEEE Symposium on Security and Privacy, 2004Co-Authors: S Evans, D Heinbuch, E Kyle, J Piorkowski, James WallnerAbstract:In most modern information systems (IS), functionality and security are Competing Design goals. Therefore, system Designers are constantly forced to make security-related trade-off decisions. Systems security engineers must build systems that are secure against real-world attacks without overengineering against any particular one. By understanding which attacks are most likely and which risks are most serious, system Designers can make informed security-related trade-off decisions. We describe a systems security engineering methodology Designers can use to make these decisions.

Novel Process and Temperature-Stable BICS for Embedded Analog and Mixed-Signal Test
13th IEEE International On-Line Testing Symposium (IOLTS 2007), 2007Co-Authors: John Liobe, Martin MargalaAbstract:This paper proposes a new current sensor Design for the arduous task of testing embedded analog and mixed-signal circuits. This proposed, wide-band, minimally-intrusive IDD sensor operates up to 230MHz, which is 2.3X faster than previously proposed Designs, and occupies 78.3% less area than another Competing Design, while achieving an inherent tolerance to process and temperature variations without sacrificing significant area. A BiST utilizing this novel IDD sensor is created and tested on a CMOS op-amp and mixer showing high fault detection sensitivity, while maintaining the performance of the DUT (device-under-test). The experiments are implemented in 0.18mum TSMC CMOS mixed- signal technology.

Novel Process and Temperature-Stable, IDD Sensor for the BIST Design of Embedded Digital, Analog, and Mixed-Signal Circuits
IEEE Transactions on Circuits and Systems I: Regular Papers, 2007Co-Authors: John Liobe, Martin MargalaAbstract:This paper proposes a new IDD sensor for built-in self-test (BIST) applications for digital, analog, and mixed-signal circuits. This novel, wide-band, nonintrusive, process and temperature-stable IDD sensor operates up to 230 MHz, which is 2.3X faster than previously proposed Designs, and occupies 78.3% less area than another Competing Design. A BIST utilizing this novel IDD sensor is created and tested on numerous digital circuits, as well as on an op-amp and a mixer, achieving up to 90% fault coverage, while maintaining the performance of the circuit-under-test. The experiments were implemented in 0.18-m TSMC CMOS mixed-signal technology.

Requirements trade-offs during UML Design
Proceedings. 11th IEEE International Conference and Workshop on the Engineering of Computer-Based Systems 2004., 2004Co-Authors: A. Andrews, P. Runeson, R. FranceAbstract:Designs almost always require trade-offs between Competing Design choices to meet pervasive system dependability requirements (e.g., security, performance and fault tolerance system goals). In some cases, dependability requirements are realized by functionality that cross-cuts Designs. Aspect-oriented modeling (AOM) methods allow developers to localize such cross-cutting functionality in Design modeling views called aspects. Aspects can be composed with other Design views to obtain an integrated view of a Design. This paper presents a technique that extends such methods to cover dependability requirements that are not directly realized by functional structures in a Design. Performance goals provide examples of such requirements. We also present a trade-off mechanism to rank feasible solutions with respect to requirements priorities between different dependability requirements. The paper applies this technique to an example that has performance, fault-tolerance, and security requirements.

A Framework for Design Tradeoffs
Software Quality Journal, 2005Co-Authors: Anneliese Andrews, Ed Mancebo, Per Runeson, Robert FranceAbstract:Designs almost always require tradeoffs between Competing Design choices to meet system requirements. We present a framework for evaluating Design choices with respect to meeting Competing requirements. Specifically, we develop a model to estimate the performance of a UML Design subject to changing levels of security and fault-tolerance. This analysis gives us a way to identify Design solutions that are infeasible. Multi-criteria decision making techniques are applied to evaluate the remaining feasible alternatives. The method is illustrated with two examples: a small sensor network and a system for controlling traffic lights.
