摘要：The purpose of the paper is to present a metric for availability based on the design of the informationsystem. The availability metric proposed in this paper is twofold, based on the operating program andnetwork delay metric of the information system (For the local bound component composition theavailability metric is purely based on the software/operating program, for the remote bound componentcomposition the metric incorporates the delay metric of the network). The aim of the paper is to present aquantitative availability metric derived from the component composition of an Information System, basedon the dependencies among the individual measurable components of the system. The metric is used formeasuring and evaluating availability of an information system from the security perspective, themeasurements may be done during the design phase or may also be done after the system is fullyfunctional. The work in the paper provides a platform for further research regarding the quantitativesecurity metric (based on the components of an information system i.e. user, hardware, operatingprogram and the network.) for an information system that addresses all the attributes of information andnetwork security.
