Abstract - Swarm intelligence is a powerful tool for tackling complex problems, and has the potential to revolutionize the field of cybersecurity. In this paper, we propose a new approach to user behavior analysis on networks using swarm intelligence algorithms. Our approach involves creating a swarm of agents to represent users on the network, and using simple rules to govern the agents' interactionswitheachother and the environment. By analyzing the emergent behavior of the swarm, we are able to classify the users on the network according to their behavior patterns. We demonstrate the effectiveness of our approach with a series of simulations, and present the results of our experiments. Our approach represents a significant advance over previous methods, and has the potential to significantly improve the security of networks by enabling more accurate and efficient analysis of user behavior. We provide a detailed implementation of our approach in the form of code, which can be easily adaptedand applied to a wide range of network security scenarios.

Key Words: Swarm intelligence, behaviour analysis, Networksecurity.
