How to identify Azure resources that need to update to TLS 1.2 or later version?

SafiyullahSA 65 Reputation points

I received a notification from Microsoft that interactions with Azure services must be secured using Transport Layer Security (TLS) 1.2 or later by October 31, 2024. I want to know which resources or services are affected and need to be updated to TLS 1.2. Can someone provide guidance or a tool to help identify these resources?

    I'd recommend going through the list of possible resources that could be using TLS 1.0 and 1.1:

    How to tell if my resource uses anything below TLS 1.2

    Then you will need to know what apps are connecting to these services and check the protocols being used.

    If this is helpful please accept answer.

    @Safiyullah S A Thanks for posting your query on Microsoft Q&A.

    In addition to the answer provided by Dillon on how to check for the TLS version for your Azure services (by checking 'Configuration'), you can go through these documents on

    We recommend the following steps as you prepare to migrate your clients to TLS 1.2:

    -Update your operating system to the latest version.

    -Update your development libraries and frameworks to their latest versions. For example, Python 3.8 supports TLS 1.2.

    -Fix hardcoded instances of security protocols older than TLS 1.2.

    -Notify your customers and partners of your product or service's migration to TLS 1.2.

    -For more detailed guidance, see the checklist to deprecate older TLS versions in your environment.

    Hope that helps.
