What is the primary purpose of a Security Information and Event Management (SIEM) system?

The primary purpose of a Security Information and Event Management (SIEM) system is to collect, analyze, and correlate security event data. SIEM systems aggregate and analyze data from various sources within an organization's infrastructure, such as firewalls, antivirus programs, and intrusion detection systems. This centralized analysis helps security teams identify potential security threats and incidents in real-time, allowing for faster detection and response.

SIEM enables organizations to keep track of security events and alerts by aggregating logs and security alerts from across their network. The correlation of the collected data assists security teams in understanding the context of incidents, spotting patterns, and identifying anomalies. This comprehensive view ensures that organizations can respond quickly to potential threats, enhancing their overall security posture.

The other options do not accurately capture the primary function of a SIEM. Secure data storage, effective cloud resource management, and enforcement of network access control policies, while important for overall security and IT management, do not encompass the key role of SIEM systems in managing and analyzing security event data.
