During the past few years, huge amount of network attacks have increased the requirement of efficient network intrusion detection techniques. Different classification techniques for identifying various real time network attacks have been proposed in the literature. But most of the algorithms fail to classify the new type of attacks due to lack of collaborative filtering technique and robust classifiers. In this paper, the authors propose a new collaborating filtering technique for preprocessing the probe type of attacks and implement a hybrid classifiers based on Binary Particle Swarm Optimization (BPSO) and Random Forests (RF) algorithm for the classification of PROBE attacks in a network.
