Which of the following best describes real-time monitoring in SIEM?

Real-time monitoring in a Security Information and Event Management (SIEM) system refers to the continuous observation of security events as they occur. This capability allows organizations to detect and respond to potential security threats immediately, rather than after a delay. By continuously tracking events, SIEM systems can aggregate data from multiple sources, analyze it for unusual patterns, and quickly alert security teams to anomalies that could indicate breaches or attacks.

This approach ensures that organizations can maintain a proactive security posture, enabling them to respond rapidly to threats, minimize potential damage, and ensure compliance with regulations. Continuous monitoring contrasts significantly with other methods that involve periodic checks or manual audits, which may leave vulnerabilities unaddressed for longer periods and increase the risk of overlooking critical security issues.
