Defense Mechanisms for Computer-Based Information Systems

A Chromosome-based Evaluation Model for Computer Defense Immune Systems

The Computer Defense Immune System (CDIS) is an artificial immune system for detecting computer viruses and network intrusions. We present a simple chromosome-based evaluation model for CDIS. In this model, the genotype space is a linear number sequence, and a digital pattern sequence is produced as the phenotype space using a number of mechanisms, including pattern mining and genetic algorithm...

Classes of Defense for Computer Systems

Computer security incidents often involve attackers acquiring a complex sequence of escalating capabilities and executing those capabilities across a range of different intermediary actors in order to achieve their ultimate malicious goals. However, popular media accounts of these incidents, as well as the ensuing litigation and policy proposals, tend to focus on a very narrow defensive landsca...

Computer based Information Systems and Managers' Work

Three categories of model are identified here: the technology impact model; the social impact model and the integrationist model, which imply different views of the ‘impact’ of information technology on work organization. These models are used to structure data from case studies conducted by the authors to explore the implications of the use of computer-based information systems for managers’ w...

A Petri-net based modeling tool, for analysis and evaluation of computer systems

Petri net is one of the most popular methods in modeling and evaluation of concurrent and event-based systems. Different tools have been created to support modeling and simulation of different extensions of Petri net in different applications. Each tool supports some extensions and some features. In this work a Petri net based modeling and evaluation tool is presented that not only supports dif...
