Secure gateway defender- a network intrusion detection system

A secure defender strives to meet accuracy and active responses. Traditional approaches towards network security largely rely on the statistical and algorithm-based designs for detecting intrusion, but have largely left response up to the network operator. We will build a NIDS which will use Apriori algorithm. The basic idea of the algorithm is to find all frequency sets in first, the frequent item sets occur at least a predefined minimum support and confidence. The system permits an early classification of the data packets by making them pass through a central server where they are processed. This early classification improves the performance. This paper focuses on building a system for network administrators to securely manage the network along with providing systems for logging and intrusion detection.
