libtissue - implementing innate immunity
In a previous paper the authors argued the case for incorporating ideas from
innate immunity into articficial immune systems (AISs) and presented an outline
for a conceptual framework for such systems. A number of key general properties
observed in the biological innate and adaptive immune systems were hughlighted,
and how such properties might be instantiated in artificial systems was
discussed in detail. The next logical step is to take these ideas and build a
software system with which AISs with these properties can be implemented and
experimentally evaluated. This paper reports on the results of that step - the
libtissue system.Comment: 8 pages, 4 tables, 5 figures, Workshop on Artificial Immune Systems

An Immune Inspired Approach to Anomaly Detection
The immune system provides a rich metaphor for computer security: anomaly
detection that works in nature should work for machines. However, early
artificial immune system approaches for computer security had only limited
success. Arguably, this was due to these artificial systems being based on too
simplistic a view of the immune system. We present here a second generation
artificial immune system for process anomaly detection. It improves on earlier
systems by having different artificial cell types that process information.
Following detailed information about how to build such second generation
systems, we find that communication between cells types is key to performance.
Through realistic testing and validation we show that second generation
artificial immune systems are capable of anomaly detection beyond generic
system policies. The paper concludes with a discussion and outline of the next
steps in this exciting area of computer security.Comment: 19 pages, 4 tables, 2 figures, Handbook of Research on Information
