An Analysis of Network Scanning Traffic as it relates to Scan-Detection in Network Intrusion Detection Systems

- Description: Network Intrusion Detection is, in a modern network, a useful tool to de-tect a wide variety of malicious traffic. The ever present prevalence of scanning activity on the Internet is fair justification to warrant scan de-tection as a component of network intrusion detection. Whilst current systems are able to perform scan-detection, the methods they use are often flawed and exhibit an inability to detect scans in an efficient and scalable manner. Existing research by van Riel and Irwin has illustrated a number of flaws present in the open source systems Snort and Bro. This paper builds on this by describing current research at Rhodes Uni-versity in which these flaws are being addressed. In particular, this re-search will address the flaws in the scan-detection engines in Snort and Bro by developing new plug-ins for these systems which take into con-sideration the improvements which are identified over the course of the research.

- Description: Softswitches have played a crucial role in next generation networks (NGNs) not only as the primary agents responsible for controlling the data and media paths between endpoints, but also as hosts of telepho-ny applications such as billing and legal intercept. Even though very useful and flexible application interfaces have been used to program these softswitches, there is much benefit that can be derived from de-coupling the application layer from the switching core. NGN architec-tures such as the IP Multimedia Subsystem (IMS) have borrowed the concept of an application server from the IT domain in order to deliver enhanced services to the network. This paper describes an initial inves-tigation into the development of a service delivery platform (SDP) based on the JAIN Service Logic and Execution Environment (JSLEE) indus-try standard, to provide advanced services that can be deployed over a telephony environment called iLanga, which is based on the open source software PBX named Asterisk.

Sing a swansong for the SABC as we know it : keep public broadcasting, redistribute the broadcaster

- Description: Behind the dragged-out confrontations around the SABC are a politics of paralysis. That's not necessarily a bad thing if the alternative is the broadcaster being a tool of a single particular force. But it's also not exactly first prize for South Africans. Power is divided across so many centres that no single force has been able to easily prevail on SABC during the year.

The Sacred Door and other Stories: Cameroon Folktales of the Beba (Makuchi)

- Description: In The Sacred Door and Other Stories: Cameroon Folktales of the Beba, Makuchi has collected thirty-three folktales of the Beba people. These stories are presented in English only. The book contains a foreword by well-known oral literature scholar, Isidore Okpewho and a preface by the author. In the foreword, Okpewho states that:“Tales like these need to be retold again and again, because the lessons they yield belong not merely to a long-forgotten historical or so-called primitive past but very much to the present times in which we live”(xi). The book therefore represents a sense of continuity between past and present. Although the tales may no longer be told in the same way that they were many years ago, the messages contained in the tales remain as relevant today as they did in the past.
