To monitor network traffic for suspicious activity and alert administrators

The primary function of intrusion detection systems (IDS) is to monitor network traffic for suspicious activities and alert administrators when potential threats are detected. IDS have the capability to analyze data packets moving through a network, looking for patterns or signatures that may indicate unauthorized access, malware, or other malicious actions. Once such activities are identified, the system generates alerts that enable network administrators to respond promptly, mitigating risks to the network's security.

This proactive monitoring is crucial in maintaining the integrity, confidentiality, and availability of data within a network, as it enables quick responses to potential breaches before significant damage can occur. Understanding how IDS operate helps organizations to bolster their cybersecurity measures effectively.
