Bridging the Gap between Security/Risk Assessment and Quality Evaluation Methods

An IT security vulnerability can be considered as an inherent weakness in a target system that could be exploited by a threat source. Most vulnerable capabilities/attributes of a system can be identified for instance with security controls in order to evaluate the level of their weaknesses. Thus, understanding the current quality acceptability level achieved for vulnerable attributes can help in turn assessing the risk and planning actions for improvement, i.e. the risk reduction by implementing the risk treatment from the impact standpoint. The underlying hypothesis in our proposal is that each identified attribute associated with the target entity to be controlled should show the highest quality satisfaction level as an elementary indicator. The higher the quality indicator value achieved per each attribute, the lower the vulnerability indicator value and therefore the potential impact. In the present work, we discuss the added value of supporting the IT security and risk assessment areas with measurement and evaluation methods and strategy, which are based on metrics and indicators. Also we illustrate excerpts of an actual case study for measurement and evaluation of a system security characteristic and attributes, and its potential risk assessment.
