ReACT provides real-time monitoring and alerting for critical RACF events, such as unauthorized access to sensitive data or modifications to user attributes, ensuring prompt responses to potential security threats. It offers a centralized administration of multiple z/OS systems, including Sysplex/Monoplex support, and allows for the delegation of routine authorization tasks to helpdesk or departmental users. The solution enables the analysis of RACF databases through a Windows-based GUI and generates audit-compliant reports without requiring direct access to the z/OS system. Additionally, it provides automatic real-time security monitoring and rollback capabilities for extensive RACF changes.
