The main purpose of a SIEM (Security Information and Event Management) system is best described by option C) Security information and event management.

A SIEM system is designed to collect, analyze, and manage security data from across an organization’s IT infrastructure. It provides real-time analysis of security alerts generated by applications and network hardware, helping organizations detect and respond to security threats more efficiently. SIEM tools aggregate log data from multiple sources, allowing for centralized visibility, compliance reporting, and incident management, thus enhancing the overall security posture of an organization.

In contrast, options A, B, and D relate to more specific functions that may be part of a broader security strategy but do not encapsulate the comprehensive purpose of a SIEM system.
