Data Security
The EAI software components of Windchill ESI do not use an external or third-party database. Most operations occur in memory. Persistence to disk occurs primarily for:
• Check pointing (state management)
• Writing to log
Windchill ESI does not encrypt data in storage or in transit. You may need to customize the Windchill ESI application to support encryption if your product structure data is particularly sensitive or must traverse unsecured network links.
Refer to the Windchill Enterprise Systems Integration Installation and Configuration Guide - SAP for details on traversing Wide Area Networks (WANs) and firewalls with TIBCO EMS and Rendezvous.
