Defining Controlled Experiments Inside the Access Control Environment

: In ICT systems and modern applications access control systems are important mechanisms for managing resources and data access. Their criticality requires high security levels and consequently, the application of effective and efﬁcient testing approaches. In this paper we propose standardized guidelines for correctly and systematically performing the testing process in order to avoid errors and improve the effectiveness of the validation. We focus in particular on Controlled Experiments, and we provide here a characterization of the ﬁrst three steps of the experiment process (i.e., Scoping, Planning and Operation) by the adoption of the Goal-Question-Metric template. The specialization of the three phases is provided through a concrete example.
