Which system is specifically designed for real-time security information and event management?

IBM QRadar SIEM is specifically designed for real-time security information and event management, which is integral in monitoring and responding to security incidents. It aggregates data from various sources, including network devices, servers, domain controllers, and more, and applies advanced analytics to identify security threats and vulnerabilities.

The capability of QRadar to analyze and correlate large volumes of security data in real time allows organizations to detect suspicious activities and respond proactively. It provides a centralized platform for security analysts to visualize and understand threats in their environment, facilitating faster incident response and improved overall security posture.

In contrast, other options such as Database Management Systems pertain mainly to data organization and retrieval; Network Traffic Analysis Tools focus on monitoring and analyzing network traffic but may not provide a comprehensive view of security events; and Data Backup Systems are designed for data recovery and protection against loss but do not specifically address security event management or threat detection.
