Abstract

The calculation of network security metrics is a complex problem which involves understanding the state and configuration of network connections, devices and protocols. This research analyses the problem of calculating network security metrics and proposes a framework which can calculate security metrics for a typical small network comprising of numerous devices, operating systems and hosts. The project will involve the configuration of virtual networks for testing the framework. CVSS or other metric scores may be used to aid the calculation of the metric. This dissertation involves some practical work which may involve setting up a virtual network which has a number of machines on the network and applying a range of scanning, probing and vulnerability testing mechanisms on the network.
