The article explores how to protect a campus computer network by using a special kind of security system called intrusion detection. The researchers designed a system based on this technology to keep users safe and protect the network. By using distributed network intrusion detection, they made sure the system watches out for potential threats in different parts of the network. This setup not only calms worries but also boosts the overall security of the computer network. The researchers found that their system can effectively safeguard the campus network and provide strong protection against cyber threats.
