On the modern battlefield, the crucial challenges in the constantly shifting formation and constantly changing physical network topology have been solved, but the cyber threat directed at them is constantly accelerating. Attacks towards the traditional network architecture have been developed for years, and they are constantly evolving to be more complex. In a defensive scenario the defensive measures in such a network are either too slow or require a disproportionate amount of resources to execute. This thesis aims to consider whether software-defined network technology could bring a change to the current state by streamlining acute configuration changes required to restrict network traffic and protect the devices on the network. \n\nThe research has been executed as a qualitative study. It is based on the concept of design science, where the initial threat scenarios are based off earlier studies, and after that by applying the methods explained in the literature review are used to explore solutions to the scenarios. The research has been defined to disregard for example the opportunities or threats that satellite data transfer in a brigade combat team\u2019s area of responsibility offer, or the specific cyber threats aimed at software-defined networking. It focuses on presenting possibilities instead. The source material used is mostly as recent as available, due to the extreme speed of technological development.\n\nThe clearest conclusion of this study is that software-defined networking could definitely provide advantages over conventional networks in some use cases. Acute configuration changes caused by network incidents, that could be used to restrict the spreading of an attack could be delivered remarkably fast to their targets without entirely crippling the network. The main reason for this is the separation of a data layer and a control layer as two separate entities, which do not allow for attacks based on conventional network devices. The study shows that the subject should be researched further, especially in the form of practical empirical testing, to confirm the validity of the presented solutions by acquiring clear, measurable results.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-11-20T11:38:34Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-11-20T11:38:34Z (GMT).
