Energy Policy, 2014
Abstract Energy lies at the backbone of any advanced society and constitutes an essential prerequisite for economic growth, social order and national defense. However there is an Achilles heel to today׳s energy and technology relationship; namely a precarious intimacy between energy and the fiscal, social, and technical systems it supports. Recently,

A New Metric to Quantify Resiliency in Networking
IEEE Communications Letters, 2012In network protocol engineering resiliency is still a relatively new and somewhat ill-defined concept. Insofar only few studies attempt to define some metric to measure and thus quantify resiliency. In this paper we propose to quantify network resiliency along multiple parameters and further we introduce a two dimensional graphical representation with ...

Strategies and Metric for Resilience in Computer Networks
The Computer Journal, 2011The use of the Internet for business-critical and real-time services is growing day after day. Random node (link) failures and targeted attacks against the network affect all types of traffic, but mainly critical services. For these services, most of the time it is not possible to wait for the complete network recovery; the best approach is to act in a

Resilience metrics for cyber systems
Environment Systems and Decisions, 2013As federal agencies and businesses rely more on cyber infrastructure, they are increasingly vulnerable to cyber attacks that can cause damages disproportionate to the sophistication and cost to launch the attack. In response, regulatory authorities call for focusing attention on enhancing infrastructure resilience.

Resilient Control System Metrics
2019Resilience of a system, particularly critical infrastructure, is of great interest to utilities and stakeholders. Consequences of natural or man-made events (e.g., Superstorm Sandy, the sequence of storms affecting the Caribbean and coast of the United States in 2017, and the Ukrainian power grid attack) have led to emphasis and increased interest in ...

Design and Assessment Methodology for System Resilience Metrics
Risk Analysis, 2019AbstractBy providing objective measures, resilience metrics (RMs) help planners, designers, and decisionmakers to have a grasp of the resilience status of a system. Conceptual frameworks establish a sound basis for RM development. However, a significant challenge that has yet to be addressed is the assessment of the validity of RMs, whether they ...

Operational Resilience Metrics for a Complex Electrical Network
2018The Electrical Distribution Network is a Critical Infrastructure which plays a primary role in citizen life. Resilience is a relevant property to be achieved as it allows the network to withstand all types of perturbations affecting its functions and allowing to provide its service with continuity. Resilience comes out from a combination of a number of

The IEEE Distribution Resiliency Working Group (DRes) is currently exploring the development of distribution system resiliency metrics. The electric utility industry currently utilizes widely accepted IEEE 1366 Reliability metrics to quantitatively measure system performance when not experiencing High Impact, Low Frequency (HILF) extreme events during ...

A Sybil-Resilient Reputation Metric for P2P Applications
2008 International Symposium on Applications and the Internet, 2008We propose a reputation-based trust model for P2P applications and study it in a security framework. This framework makes it easy to reason about the resilience of the reputation metrics against Sybil attacks. We show that using the PageRank reputation metric in a P2P system can make it very vulnerable to Sybil attacks. We then propose a new reputation

A Dimensionless Graceful Degradation Metric for Quantifying Resilience
2012 IEEE Sixth International Conference on Self-Adaptive and Self-Organizing Systems Workshops, 2012Many self-* properties are variations on the same theme: resilience of a system to changes in itself or the conditions under which it operates. Quantifying resilience is difficult, however: there are no metrics of resilience that are readily comparable across systems, and the space of possible changes is typically prohibitively large.
