Abstract	One of the main security objectives for systems connected to the Internet which provide services like Voice over Internet Protocol (VoIP) is to ensure robustness against security attacks to fulfill Quality of Service (QoS). To avoid system failures during attacks service providers have to integrate counter-measures which have to be tested. This work evaluates a test approach to determine the efficiency of counter-measures to fulfill QoS for Session Initiation Protocol (SIP) based VoIP systems even under attack. The main objective of the approach is the evaluation of service availability of a System Under Test (SUT) during security attacks, e.g., Denial of Service (DoS) attacks. Therefore, a simulated system load based on QoS requirements is combined with different security attacks. The observation of the system is based on black-box testing. By monitoring quality metrics of SIP transactions the behavior of the system is measurable. The concept was realized as a prototype and was evaluated using different VoIP systems. For this, multiple security attacks are integrated to the testing scenarios. The outcome showed that the concept provides sound test results, which reflect the behavior of SIP systems availability under various attacks. Thus, security problems can be found and QoS for SIP-based VoIP communication under attack can be predicted.
