What is an Intrusion Detection System (IDS)? Discuss the other network security measures besides IDS.

An Intrusion Detection System (IDS) is a security tool that helps in detecting any unauthorized or malicious activities on a computer system or network. IDS operates by examining traffic flowing across the network or system, looking for suspicious behavior that indicates an intrusion attempt. If an intrusion is detected, the IDS will alert the administrator or security team, allowing them to investigate and respond to the attack. IDS can be deployed in different forms, including network-based IDS (NIDS), host-based IDS (HIDS), and hybrid IDS.
