| Abstract | Moving Target Defense (MTD) has been emerged as a promising countermeasure to defend systems against cyberattacks asymmetrically while working well with legacy security and defense mechanisms. MTD provides proactive security services by dynamically altering attack surfaces and increasing attack cost or complexity to prevent further escalation of the attack. However, one of the non-trivial hurdles in deploying MTD techniques is how to handle potential performance degradation (e.g., interruptions of service availability) and maintain acceptable quality-of-service (QoS) in an MTD-enabled system. In this paper, we derive the service performance metrics (e.g., an extent of failed jobs) to measure how much performance degradation is introduced due to MTD operations, and propose QoS-aware service strategies (i.e., drop and wait) to manage ongoing jobs with the minimum performance degradation even under MTD operations running. We evaluate the service performance of software-defined networking (SDN)-based web services (i.e., Apache web servers). Our experimental results prove that the MTD-enabled system can minimize performance degradation by using the proposed job management strategies. The proposed strategies aim to optimize a specific service configuration (e.g., types of jobs and request rates) and effectively minimize the adverse impact of deploying MTD in the system with acceptable QoS while retaining the security effect of IP shuffling-based MTD. |
