Large network systems elevate the levels of e f iciency and effectiveness of organisations by improving systems integration. This improved integration of computer networks and information systems is accompanied by increased risks of intrusion and compromise. Survivability of networks and information systems in face of these risks becomes an importantaspect in the effective functioning of a n organisation. The unbounded nature of today's networks and the Internet make it impossible to fore see all possible risks and cover the systems against all possible attacks. In this scenario, it becomes necessary that the network be designed to resist possible attacks, recognise attacks and recover from attacks. The open-ended nature of this problem requires that flexible architectures be employed t o improve survivability. Agent technology is a highly flexible and robust paradigm f o r building large scale distributed systems. In this paper, we present a n agent-based framework f o r Survivable Network Systems. 0-7803-5258-0/99 $10.00 0 1999 IEEE
An A utonomous Distributed System ADS is a collection of autonomous entities, which realize a given function through mutual interactions. This concept of ADS allows the development of systems, which involves a large number of independent entities and dynamically changing structure t o m e et the evolving user requirements. Agents are characterised by the concepts of situatedness, exibility and autonomy. A multi agent system is a group of interacting agents. In this position paper, we explore the relevance of agent technology to the design and implementation of autonomous distributed systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
