In AE Services Release 7.1.x, only the Transport Layer Security (TLS) 1.2 protocol is enabled by default. The lower level TLS protocols 1.0 and 1.1 are disabled by default.
![]() | Note |
According to the National Institute of Standards and Technology (NIST) Special Publication 800-52, TLS version 1.1 is required, at a minimum, in order to mitigate various attacks on the TLS 1.0 protocol. The use of TLS 1.2 is strongly recommended. |
This change may cause older AE Services clients, that is users of AE Services 7.0 and earlier that are using TLS to fail to establish a secure socket connection to the AE Services 7.1.2 server. In order to achieve a more secure client/server socket connection, we encourage current client applications to use AE Services 7.1.2 SDK where the TLS 1.2 protocol is supported. If upgrading to AE Services 7.1.2 SDK is not a viable option, an AE Services administrator can enable the TLS 1.1 and/or TLS 1.0 protocol via the AE Services Management Console Web interface.

All three TLS protocol versions can be active at the same time. This allows a gradual migration of current client applications to move towards a more secure TLS protocol over a period of time. |
