What is the primary role of an intrusion detection system (IDS)?

The primary role of an intrusion detection system (IDS) is to monitor network traffic for suspicious activity. An IDS is designed to analyze traffic patterns and identify potential security threats, such as unauthorized access attempts or unusual behaviors that may indicate a breach. By continuously scanning network communications, the IDS can help organizations detect and respond to potential intrusions in real-time, thereby adding an essential layer of security to their network infrastructure.

The ability to recognize and alert on threats is critical for maintaining the integrity and confidentiality of data, making the monitoring of network traffic a fundamental function of any effective security posture. This proactive approach empowers security teams to investigate alerts promptly and take necessary actions to mitigate risks before they escalate into more significant issues.
