This is a notice of the upcoming change in Q1 2022 with support of TLS 1.0/1.1 on Informatica Intelligent Cloud Services Secure Agents.
Support for TLS 1.0/1.1 will no longer be enabled by default on Informatica Intelligent Cloud Services Secure Agents (“Secure Agents”) from Q1 2022. Only TLS 1.2 will be enabled by default and customers requiring TLS 1.0/1.1 support will need to manually re-enable the older TLS protocols.
Informatica will continue to support TLS1.0/1.1 by default until that time.
In conjunction with the above deprecation notice, OpenJDK began disabling TLS 1.0 and TLS 1.1 by default in April 2021. Informatica Intelligent Cloud Services will be upgrading the Secure Agent JDK to version 8u302 of OpenJDK during the October 2021 major release.
Informatica will overwrite the default JDK 8u302 setting to continue supporting TLS 1.0 and TLS 1.1 until the first Major release in Q1 2022 to allow customers time to prepare for TLS 1.2 default configuration.
This will require you to review all the endpoints (databases, applications, mainframes, etc.) for TLS 1.2 support and ensure they are configured to support TLS 1.2. It is advised to deploy a test Secure Agent configured to only support TLS 1.2 as described in KB Article and test their connectivity and IICS workloads.
