Intrusion Detection and/or Prevention Systems (IDPS) represent an important line of defense against a variety of attacks that can compromise the security and proper functioning of an enterprise information system. Although many IDPS systems have been proposed, their appropriate configuration and control for effective attacks detection/prevention and efficient resources consumption has always been challenging. The evaluation of the IDPS performance for any given security configuration is a crucial step for improving real-time capability. This paper aims to analyze the impact of security enforcement levels on the performance and usability of an enterprise information system.
