[edit] SIPPING

SIPPING BAYES - A Session Initiation Protocol (SIP) investigation into ``man-in-the middle" attacks on a SIP User Agent (UA) and the use of a naïve Bayes ``SIP message" classifier.

The Session Initiation Protocol (SIP) is not an easy protocol to secure. RFC 3261 [1], identifies a few of the more common security risks found in most deployments of SIP. The risks associated with SIP are: ``registration hijacking", ``impersonation of server", ``message body exploitation", ``mid-session exploitation" and ``susceptibility to DoS". We will investigate these vulnerabilities and implement key attacks for demonstration purposes.

Some of these exploits can be avoided by using a Peer-to-peer (P2P) architecture [2]. However, there are security risks inherent in P2P that need to be addressed. A survey of the current state of P2PSIP will be undertaken and these security issues will be examined.

Bayes' theorem has had many applications to Computer Science over the last ten years [3]. The final part of SIPPING BAYES will attempt to construct a naïve Bayes ``SIP message" classifier.

[edit] STEP

Scripture Tools for Every Pastor (STEP) aims to provide far-flung believers, free of charge, with the best Bible software tools capable of working on phones and on low-specification computers with little or no always-on Internet facilities.

Tyndale House (Cambridge) is one of three libraries in the world that are dedicated solely to the scholarly study of the Bible -- the others are Ecole Biblique in Jerusalem and the Pontifical Biblical Institute in Rome. It was established as an independent library to give scholars the tools to provide a firm academic foundation for positive biblical research.
