Risk-Aware Design and Management of Resilient Networks

Optimization/simulation-based risk mitigation in resilient green communication networks

“…A proposal of linear optimization of risk mitigation strategies is outlined in Chołda (2014). In fact, in our previous works (Chołda et al, 2014b;Chołda and Jaglarz, 2015), we propose optimization approaches based on risk mitigation, but do not elaborate on the precise optimization/simulation-based approach to obtain the exact results, as is done here.…”

Energy-efficiency versus resilience: risk awareness view on dimensioning of optical networks with a sleep mode

“…From the business viewpoint, basic responses (e.g., risk avoidance, transfer, or acceptance [16,18]) can be very different, but a crucial option in the design of resilient networks is risk mitigation. It involves recovery methods to decrease the risk R by reducing impact (i.e., penalties) of failures.…”

“…A proposal of linear optimization of risk mitigation strategies is outlined in [18]. Vajanapoom and Tipper [58] present a set of papers on the topic, with the most comprehensive presenting linear programming-based models applying the risk exposure measure.…”

“…It follows the plan-do-check-act philosophy of the Deming cycle [18,65] and organizes how businesses approach the analysis and optimization of responses (recovery methods in our case) to adverse random events (failures), which are described by risk engineering. Risk is understood as "an uncertain event or condition that, if it occurs, has a positive or negative effect on an objective" [35], where each operator's objective is to increase profits and minimize losses.…”

Enterprise-oriented Cybersecurity Management

“…Typical decisions that are relevant in the technical context are as follows: acceptance when nothing is done about the recognized risks (no changes in comparison to the actual state are necessary); avoidance of situations where threats take place (elimination of a problematic information system with many vulnerabilities); reduction of the likelihood (addition of a firewall decreasing the number of successful attacks); mitigation of the impact, the most popular decision (encryption of data so that it cannot be used even if stolen). Three most common strategies apply to mitigation [18], [19], see • Risk minimization: choice of the minimum impact possible; can be very costly but might be the first choice especially in critical infrastructures, where the public good is most important.…”
