The best method for analyzing network performance is to perform a baseline check on performance.
A system called an intrusion detection system (IDS) watches network traffic for unusual activity and issues notifications when it is seen.
While an IDS's major duties are anomaly detection and reporting, certain intrusion detection systems are also equipped to respond to suspicious activity or abnormal traffic by blocking traffic coming from suspect Internet Protocol (IP) addresses.
An intrusion prevention system (IPS), in contrast to an IDS, monitors network packets for potentially harmful network traffic. However, unlike an IDS, an IPS's main objective is to prevent threats after they have been identified.
