9. Securing a Multi-Tier connection using SSL

9.1. Overview

As of version 5.2, OpenLink UDA now comes with optional support for using OpenSSL to encrypt the data layer between generic client and request broker / agent.

Features of the SSL implementation:

• secures connections to both the broker and all database agents
• encryption is optional, although it can be made mandatory
• the same connection endpoint endpoint (port) handles both encrypted and non-encrypted clients
• fully backward-compatible
• per-agent certificates
• all changes are in the OpenLink communications layer: there is no need to change any of the database agents to cater for SSL.
