An agent based Bayesian forecasting model for enhanced network security. (2001)
Presentation / Conference Contribution
Pikoulas, J., Buchanan, W. J., Mannion, M., & Triantafyllopoulos, K. (2001, April). An agent based Bayesian forecasting model for enhanced network security. Presented at ECBS 2001

Security has become a major issue in many organisations, but most systems still rely on operating systems, and a user ID and password system to provide user authentication and validation. They also tend to be centralized in their approach which makes... Read More about An agent based Bayesian forecasting model for enhanced network security..
