Product Overview

The architecture of z/MQSSX comprises several key components designed to secure external access to IBM MQ on z/OS. The Channel Interceptor is a core component, intercepting incoming channel connections to enforce security policies. The Security Server is responsible for evaluating access requests based on configured rules.

The Configuration Manager handles the storage and retrieval of configuration data, including access rules, IP address restrictions, and SSL DN settings. These components communicate through z/OS system services and MQ APIs. The product does not use any specific database or storage mechanism beyond the z/OS file system for configuration files.

The Security Server and Channel Interceptor interact to enforce access control. The CLI provides the primary administrative interface for configuring and managing the system. The product supports access control based on logon ID, IP address, and SSL DN.

It does not provide built-in monitoring dashboards. The product uses the underlying SSL/TLS configuration for secure communication. The product integrates with the z/OS security infrastructure and requires z/MQAUSX for user authentication.

The product provides logging of security events and access attempts.
