In this paper, the authors explain the modeling and implementation of an Intrusion Detection System (IDS) with focus on internally generated intrusions on a multi-Disciplinary campus network using Ahmadu Bello University (ABU) Zaria as a case study. A.B.U Zaria campus network is a complex network covering three campuses, 12 faculties and over a hundred Departments and as such there are varied types of users with diverse application requirements. Traffic data for a period of 24 months comprising of local to local and local to remote were used in developing the knowledge base of the IDS. The overhead of each packet derived from properties and composition of each packet is determined and used to form the behavior base of the IDS.
