ASF: An attack simulation framework for wireless sensor networks

Wireless Sensor Networks are vulnerable to quite a good deal of logical and physical security attacks. However, providing security countermeasures for every possible attack is practically unfeasible for cost and performance reasons. Thus, it is vital to properly rank security attacks in order to establish priorities and then select appropriate countermeasures. In this paper, we present ASF, an attack simulation framework that allows us to describe attacks and quantitatively evaluate their effects on the application and network behavior and performance. ASF helps users to evaluate the impact of an attack, a crucial step in the attacks ranking activity. Also, we present an early prototype of ASF built on top of the popular simulator Castalia. Finally, we show the capabilities of ASF by analysing four attacks against a realistic application scenario.
