Abstract
This paper outlines a tool developed with the purpose of creating a simple configurable emulated network environment that can be used in cyber defence exercises. Research has been conducted into the various related subject areas: cyber defence exercises, network threats, network emulation, network traffic replay, network topologies, and common network services. From this research a requirements specification was produced to encapsulate the features required to create this tool. A network, containing many of the aspects researched, was designed and implemented using Netkit-NG to act as a blueprint for the tool and to further knowledge in the construction of an emulated network. Following this the tool was developed and tested to ensure requirements were met.
Highlights
Computer security is an essential part of keeping an organisation’s data safe from malicious affect
Research was conducted into common network services and cyber defence exercises in the literature review
A networked system was planned and created, this network can be configured to a users specifications which gives multiple learning opportunities in the practical implementation of networks and programming
Summary
Computer security is an essential part of keeping an organisation’s data safe from malicious affect. The tool produced by this work allows professionals to receive training in the security of sensor/actuator networks in a variety of user definable network scenarios This tool allows the production of a complex virtual network, and the simulation of network traffic, without requiring an extensive background in that area by creating the virtual network based solely on user input. This allows more focus to be placed on training professionals than setting up and maintaining the network, the attack simulation element of this tool means common threats can be simulated with ease and without intimate knowledge of the tools required to attack a network, shifting focus more on defence and protection of a network. Once this had been done, the papers were read in more detail and the content used where appropriate
