Netnod is a small, high-tech firm based in Sweden which provides services at the core of the Internet, such as Internet Exchange services, data transport, DNS services, and time and frequency services. Netnod is at the forefront of secure and robust services. At Netnod we mainly design security through diversity, that is by composing systems through many different nodes in many different levels so that there is no single point of failure. In terms of security our systems focus on providing availability and integrity, even in extreme scenarios. There is, however, no standard or agreed upon way for quantifying the security of such a system. Qualitatively, our premium services have full redundancy and no downtime at service level., But we need a way to quantify our robustness, or uptime, in verifiable numbers. This thesis concerns the creation or design of such a quantifying scheme. Qualifications This thesis project is aimed at students in computer science and engineering with an interest in security. The thesis should preferably be done by two students, 30hp each during the spring of 2025. The students should have good language skills in both English and Swedish. Practicalities Netnod will provide an on-site supervisor with relevant academic qualifications. Netnod will also provide necessary equipment and a one time compensation upon completion of the thesis project. Location The students are expected to be partly present at the Netnod main office in Solna, Stockholm. Application Are you interested in applying for this Master's Thesis?
