[Reminder] Security Alert Relating to TLS 1.2 and Microsoft O365
Microsoft O365 Will Stop Support for TLS 1.0 and 1.1 in October of 2018
On October 31st, 2018, Microsoft Office 365 will no longer support the use of TLS 1.0 or 1.1 for communications. Once Office 365 deprecates support for these protocols, all communications to and from Office 365 servers will need to use TLS 1.2 and Polycom CX500, CX600, CX3000 will no longer connect or be supported.
Devices will not register to any Skype for Business server if TLS is updated to TLS 1.2
If upgrading to TLS 1.2 using Skype for Business Servers (on-premises), the additional devices listed below will no longer be able to register to Skype for Business or be supported. Compliance requirements such as Payment Card Industry Date Security Standard (PCI-DSS) will require that customers implement a more secure encryption protocol – TLS 1.1 or higher (TLS v1.2 is strongly encouraged) by June 30th 2018 in order to meet the PCI Data Security Standard (PCI DSS) for safeguarding payment data.
Polycom is investigating and will continue to investigate all products and product lines to determine if there will be an impact. At this time, it is known that the following products will be impacted by this change in support:
• Polycom CX500 phone
• Polycom CX600 phone
• Polycom CX700 phone
• Polycom CX3000 conference phone
• Polycom CX8000 Skype Room System
