Experience with Emerald to Date

摘要

After summarizing the EMERALD architecture and the evolutionary process from which EMERALD has evolved, this paper focuses on our experience to date in designing, implementing, and applying EMERALD to various types of anomalies and misuse. The discussion addresses the fundamental importance of good software engineering practice and the importance of the system architecture - in attaining detectability, interoperability, general applicability, and future evolvability. It also considers the importance of correlation among distriubted and hierarchical instances of EMERALD, and needs for additional detection and analysis components.
