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)
This paper proposes an alternative approach to modelling the formula attribute within the context of security metrics. This approach seeks to correct past errors by treating a security metric like a set, and inserting a component that addresses the set intersection between the security elements. The work consists in to define the model, explain the(More)
The proposed work is to verify the performance and security of different cryptographic algorithms in a en-crypted VPN (Virtual Private Network), created to provide confidentiality in the network VoIP traffic. The performance tests of the algorithms will occur in various network scenarios, simulating some problems like latency, packet loss, out of order(More)
