Initial Public Release
In order to address the revised Payment Card Industry Data Security Standard (PCI DSS), Unified Contact Center Enterprise (UCCE) Release 11.6 REMOVES support for Transport Layer Security (TLS) protocol 1.0 and 1.1 and ADDS support for TLS 1.2.
Database drivers that give applications access to the UCCE database need to be revised in order to add support for TLS 1.2 or database access operations will fail (even if encryption is not used). OEMs and partners that make products that connect to the UCCE database are required to adjust their interfaces to support TLS 1.2 if they do not already.
Note: There is no impact to customers for UCCE 10.5 and 11.x. These support TLS 1.0, 1.1, and 1.2.
The stricter TLS enforcement is introduced with UCCE Release 11.6.
UCCE database access operations will fail from third-party applications if the database driver supplied does not support TLS 1.2. Applications that access the UCCE database need to be revised in order to add support for TLS 1.2.
Implementation of this change allows uninterrupted access to UCCE data and improves security protection.
UCCE database access operations fail from third-party applications.
TLS 1.2 support in a third-party application needs to be verified with the vendor or confirmed by a test before UCCE 11.6 is deployed to the production environment. This includes third-party application access to Administrative Workstation (AW), Historical Data Server (HDS), Logger, and custom integrations.
The OS Version affected is Windows 2012.
UCCE software partners should proactively add TLS 1.2 support to their applications so that they are prepared to support UCCE with TLS 1.2 at the Release 11.6 first customer shipment, which is expected approximately September 2017. Customers should proactively reach out to third-party application vendors for updates that support TLS 1.2.
The new TLS 1.2 protocol support will be described in the UCCE Release 11.6 documentation.
