Oracle has released support for TLS 1.2 in Oracle E-Business Suite 12.1 and 12.2. Previously, Oracle E-Business Suite only supported SSLv3 and TLS 1.0, which are no longer approved for use with Federal systems and are not PCI-DSS compliant as of June 2014. For TLS 1.2 support, new My Oracle Support (MOS) documents are available:
Enabling TLS in Oracle E-Business Suite Release 12.2 (Doc ID 1367293.1)
Enabling TLS in Oracle E-Business Suite Release 12.1 (Doc ID 376700.1)
Oracle E-Business Suite 11.5 and 12.0 are desupported, therefore, these versions will continue to only support SSLv3 and TLS 1.0.
Integrigy recommends all Oracle E-Business Suite implementations use an external SSL/TLS termination point, such as an F5 BIG-IP load balancer, rather than the Oracle E-Business Suite TLS implementation in order to provide a more robust TLS implementation and allow for faster patching of the SSL technology stack. In addition, an external TLS termination point is usually maintained by network and/or security staff for multiple applications, thus off-loading this responsibility from the Oracle DBAs who often have only limited experience with the complexity of network encryption and certificates. Although, the one disadvantage is that the network traffic between the load balancer and Oracle E-Business Suite application server is unencrypted, however, this is normally limited to VLANs within the data center.
