This work proposes the development and application of specific security metrics for metropolitan broadband access networks that aim to measure the efficiency of security programs and support action planning against detected problems. The approach presented in this work show metrics developed for these networks and parameters for metrics definition. This(More)
Finding relevant metrics in information security is an important but difficult problem. In this paper, we propose to empirically investigate the relevance of different security metrics that could be derived from intrusion prevention system (IPS) alert events and computer security incident data. Based on the data provided by the University of Maryland, we(More)
The purpose of this work is to evaluate the quality of encrypted VoIP calls with different encryption algorithms through OpenVPN software, in order to identify differences in results between encryption algorithms and also differences between non-encrypted and encrypted calls. This evaluation will take into account the MOS (Mean Opinion Score), a method to(More)
—The increasing demand for latency sensitive services through the Internet imposes the development of networks capable of delivering quality of service. These networks require the use of enhanced traffic management tools. This paper performs an analysis of IP telephony or VoIP traffic considering Internet Protocol Detail Record (IPDRs). When a VoIP call(More)
