What is a major role of a SIEM in a cybersecurity framework?

1. Regulatory compliance

2. Data encryption

3. Security operations automation

4. Incident detection and reporting

The correct answer is: Incident detection and reporting

A Security Information and Event Management (SIEM) system plays a crucial role in incident detection and reporting within a cybersecurity framework. Its primary function is to aggregate, analyze, and manage security data generated from various sources across an organization's IT infrastructure. By providing real-time insights into potential security incidents, a SIEM helps security teams identify and respond to threats more quickly and effectively. The SIEM collects logs and events from different devices, such as firewalls, servers, and intrusion detection systems. It applies correlation rules to detect patterns that may indicate a security breach or abnormal behavior. This capability allows organizations to proactively monitor their networks and systems, enabling timely detection of incidents, which is vital for minimizing potential damage. In addition to detecting incidents, a SIEM offers comprehensive reporting features that help organizations understand the nature, scope, and timeline of security events. This functionality is essential for compliance audits and for maintaining a clear record of security incidents. While regulatory compliance and security operations automation are important aspects of cybersecurity, the primary role of SIEMs is centered on incident detection and reporting. Data encryption serves a different purpose, focusing primarily on protecting data integrity and confidentiality rather than managing security events in real-time.
