Executive Summary

Internet applications, such as Email, VoIP and WWW, have been enhanced with many features. However, the introduction and modification of features may result in undesired behaviors, and this effect is known as feature interaction-FI. FI resolution may be implemented by a Feature Manager, which is directed by a set of interdiction formulas. On the other hand, the approach by interdiction may eliminate all features candidate for execution, and this result on a feature denial of service. This paper analyzes how feature denial of service can be detected, with a design stage algorithm. The detection algorithm has a time complexity of the quadratic of interdiction formulas.
