Which of the following best describes the role of an IDS in cybersecurity?

The role of an Intrusion Detection System (IDS) in cybersecurity is fundamentally about monitoring and analyzing network traffic for suspicious activity. An IDS is designed to detect unauthorized access attempts, attacks, and other potentially harmful behaviors within a network. By continuously observing network data, the system can identify patterns and anomalies that may indicate a security breach.

When suspicious activity is recognized, an IDS sends alerts to system administrators, enabling them to respond quickly to potential intrusions. This proactive approach allows organizations to maintain their security posture and mitigate risks effectively. In contrast to other options, which focus on eliminating threats or managing access rights, the primary function of an IDS is detection and analysis rather than prevention or management.

The emphasis of an IDS on real-time monitoring distinguishes its role in an overall cybersecurity strategy, making it essential for maintaining the integrity and security of networked environments.
