    Continent-based Comparative Study of Internet Attacks
    (Springer, Berlin, Heidelberg, 2011) Rai, Idris A.; Matsiko, Perez
    We have deployed a honeypot sensor node in Uganda that is connected to a distributed honeypot system managed by Leurrecom.org Honeypot project, which constitutes of a large number of different honeypot sensors distributed across different continents. Once joined the project, the system allows access to the whole dataset collected by all sensors in the distributed system. We use the data collected by the honeypot sensors for a period of six months to compare the attacks that have been detected by honeypot sensors in Africa to the attacks detected by sensors in other continents. Our findings reveal that sensor nodes in Africa experience a significant number of attacks. In some cases, the number of attacks for African sensor nodes is significantly higher than many sensors in developed countries. This shows that network attacks are independent of location and Internet popularity in a country. That is, low Internet penetration level in African countries does not mean that networks in Africa are safe from external attacks. In fact, the results further indicate that some attacks are highly likely guided against specific networks.

    NREN Network Security: A case study of Uganda Christian University ICT Infrastructure
    (2013) Matsiko, Perez; Kiden, Sarah
    The long wait for high speed access to the Internet is finally coming to an end. National Research and Education Networks (NRENs) are being connected to the rest of the world through high speed fiber optic cables. This paper focuses on NREN security with Uganda Christian University (UCU) as a case study. It discusses how regional and national reseach and education networks will signifiantly lower bandwidth costs for the member institutions. It goes ahead to discuss the initial UCU ICT infrastructure, security practices and implementation, and then suggest recommendations based on lessons learnt and experiences.
