# Enforcing a minimum TLS version in the Tools for PowerShell
<a name="enforcing-tls"></a>

To increase security when communicating with Amazon services, you should configure the Tools for PowerShell to use the appropriate TLS version. For information about how to do this, see [Enforcing a minimum TLS version](https://docs.amazonaws.cn/sdk-for-net/v4/developer-guide/enforcing-tls.html#enforcing-tls-ps) in the [Amazon SDK for .NET Developer Guide](https://docs.amazonaws.cn/sdk-for-net/latest/developer-guide/).

TLS 1.3 is the prerequisite to enable post-quantum cryptography, which may require additional actions or configurations. To learn more, see [Enabling hybrid post-quantum TLS](https://docs.amazonaws.cn/sdkref/latest/guide/pqtls-details.html) in the *Amazon SDKs and Tools Reference Guide*.
