Security is becoming a "hot topic" in Computing, and conferences are increasingly giving space to developments in this area. For the second part of the assessment, you are required to select a topic within the realm of security and write a paper about a key development relating to that topic. You should locate the topic within the broader context of security and indicate what the key issues are. You should also examine the potential impact of the development you cover, both on the community at large and potentially, if deployed, on an organisation. You should indicate the sort of security threats that have to be dealt with, and the ways in which such threats can be countered by means of the development you are reviewing.
