Security visualization has been focused largely on graphic representation of data and relationships between network activity, security sensor output, and attacker activity. Visual analysis tools have not been designed to facilitate the analysis of data related to defender activities and decisions. This paper reports on the initial effort of a research team to use visual analytics to support the modeling of the computer network defense (CND) decision process of an organization. We describe a tool to support the visual analysis of a hierarchical decision structure represented in a portable, file-based database. The tool visualizes and traces relationships between decision goals, sub-goals, decisions, information requirements, and data sources.

The “New Economy is rapidly being adopted on a global scale as corporations vie for new competitive positions and defensive responses. Incumbents” so-called “bricks'n'mortar corporations” are generally finding it challenging, but usually rewarding, to extend their business practices to the internet. New entrants” so-called “Dot Com companies” are unfettered from institutional rigidity and thus have an enormous opportunity to gain market share, but at the same time are frequently challenged to provide the same levels of brand awareness, product and service as at least some of the incumbents. In this presentation we consider how internet infrastructure software is evolving, and its implications for both brick'n'mortar and dot com organisations.

Many object-oriented programming language implementations have been estcndcd to support persistence, dist,ribut,ion or atomicity by integrating the necessary a,dditional support, with t,he language's runt,ime library.We argue tha.t a better approach is to provide a. Generic Runtime library (the GRT) which imple-ments that part of the support which is independent.of any langua.ge.The GRT should be designed to interfa.ce to a langua.ge'sexisting runtime in such a way that the language's local object reference format and invocation mechanism can be retained.Hence exist.ingcompilers do not necessarily have to be modified, and a range of different object,-oriented languages can be supporkd simultaneously.This a.pproach 1la.s significant merits including: the ease with which a la.nguage ca.n be extended; the sophistication of the underlying support immediately available to a. la.nguage implementer; a.nd the ability to support fine-grain& language interworking.

Abstract The paper presents a simple single layer protocol covering the functions of X25 levels 2 and 3. It can be used on synchronous or asynchronous lines, such as employed for normal computer terminals. It requires no special hardware, and can use the standard device driver software supplied by manufacturers. The protocol has been working successfully for over two years, and could be of interest to networking projects with limited resources.
