Abstract: While high-speed computer networking and the Internet brought great convenience, a number of security challenges also emerged with these technologies. Amongst different computer network security threats, like viruses and worms, botnets have become one of the most malicious threats over the Internet. In this paper, we describe key research challenges in developing effective intrusion detection systems for botnet command and control traffic detection. Then, we outline a new approach to address such challenges, which is based on voting between intrusion detection methods to collaboratively identify command and control traffic. Each detection method analyzes the network traffic to detect one technique used for command and control communications. Four detection methods are initially investigated, these are: malicious IP address, malicious SSL certificate, domain flux and Tor connection detection. Initial analysis shows that the proposed voting-based intrusion detection significantly reduces

Abstract: This paper examines the Zimbabwean educators’ perceptions about e-learning systems in pedagogy. We use the term “educators” to refer to the teaching staff at a university context. The paper sought to present the views of the educators about e-learning. It is our assumption that these views could assist in explaining the existent second order digital divide currently persisting in higher education institutions in African developing nations such as Zimbabwe. The digital divide has resulted in a mismatch between the wide spread investment and the actual use of Information and communication technologies (ICT) like the e-learning systems. The anticipated contributions of such systems to education are yet to materialize since their pedagogical use in teaching and learning is still at its infancy. Higher education institutions are being robbed of the returns from the costly technological investments while digital natives are deprived of the ICT affordances, which their first world counterpart
