Internet and its related infrastructure have achieved a great developmental leap during the last decade. However, along with the development there is more concern about the security issues. Intrusion Detection System (IDS) is a system that detects an attack and raises an alert. Individual IDS has its limitations in terms of attack coverage and number of false positives. This paper shows the fusion of multiple IDS having heterogeneous nature. However, the success of the fused system depends on the effectiveness of individual IDS involved in fusion process.
