ETF/A

The core architecture of ETF/A is designed around a modular approach, with several key components interacting to provide a secure and auditable firecall facility. The `Firecall Request Processor` is the entry point, receiving requests from authorized users. This component validates the user's identity and checks their permissions against predefined rules.

The `Access Control Engine` then interfaces with CA ACF2 to grant temporary access. This engine uses the CA ACF2 API to modify access control lists (ACLs) or other security settings, providing the requested privileges. The `Audit Logging Module` is responsible for recording all firecall activities.

This includes the user's identity, the resources accessed, the time of access, and the duration of the elevated privileges. The communication between these components is primarily through z/OS system services and CA ACF2 interfaces. ETF/A does not use a separate database; it relies on CA ACF2's security database for user and access information.

The system's network requirements include connectivity to CA ACF2 and other z/OS components. The system supports RBAC with role-based permissions. The configuration files are typically maintained within the CA ACF2 environment.

The system uses standard z/OS security protocols for communication. The system provides detailed audit logs, which can be used for security analysis and compliance reporting. ETF/A's design prioritizes security, auditability, and ease of use, making it a valuable tool for managing privileged access in a z/OS environment.
