Identifying Suitable Attributes for Security and Dependability Metrication
Erland Jonsson, L. Pirzadeh · Chalmers Publication Library (Chalmers University of Technology) · 2013
In this paper, we suggest a framework for security and dependability metrics that is based on a number of non-functional system attributes. The attributes are the traditional security attributes (the “CIA”) and a set of dependability attributes. Based on a system model, we group those attributes into protective attributes and behavioural attributes and propose that metrication should be done in accordance. We also discuss the dependence between these two sets of attributes and how it affects the corresponding metrics.The metrics themselves are only defined to a limited degree. The concepts of security and dependability largely reflect the same basic system meta-property and are partly overlapping. We claim that the suggested approach will facilitate making quantitative assessment of the integrated concept of security and dependability as reflected by those attributes.
