Which access control feature can provide notifications of unauthorized attempts?

The feature that provides notifications of unauthorized attempts is related to intrusion detection alerts. This function is specifically designed to monitor for unusual activities or breaches in security, sending immediate notifications to administrators or security teams when unauthorized access is detected.

Intrusion detection systems play a crucial role in maintaining security by analyzing various input signals, such as failed access attempts and unauthorized entry attempts. When the system identifies suspicious behavior, it triggers alerts to notify users of potential security breaches, allowing for prompt responses to mitigate risks.

While other options can contribute to overall security and access control, they focus on different aspects. Monitoring can involve reviewing access patterns but may not directly produce real-time alerts for unauthorized actions. Mobile alerts typically serve to notify users of changes in status or confirm successful access rather than alert for unauthorized attempts. Audit trail logging is essential for reviewing access history and compliance but does not provide immediate notifications of unauthorized attempts, serving more as a record-keeping feature rather than a proactive alert system.
