[Reference: https://subscription.packtpub.com/book/networking-and-servers/9781782174905/5/ch05lvl1sec38/differentiating-between-nids-and-nips, , https://owasp.org/www-community/controls/Intrusion_Detection, A NIDS (Network Intrusion Detection System) is a security solution that monitors network traffic for signs of malicious activity, such as attacks, intrusions, or policy violations. A NIDS does not affect the availability of the company’s services because it operates in passive mode, which means it does not block or modify traffic. Instead, it alerts the network administrator or other security tools when it detects an anomaly or threat.
