Does ETM/IPaaS support mTLS authentication? 

The context for this question is the creation of an ETM HTTP source channel and/or HTTP Request Mappers that we wish to authenticate to a suppliers kafka REST proxy. This proxy has a preferred authentication scheme of utilizing mTLS to securely authorize our supplier to our network, and vice versa. The use of passwords is possible, but is less secure and triggers higher levels of scrutiny during risk assessment, and is thus as a general rule not a preferred method.

I can only find information about the use of certificates for OAuth, and its lack of inclusion under Authentication would hint at mTLS not being supported. I’m however asking in case there’s something I’ve missed or misunderstood in the possibilities presented in the other options.

Thank you very much for your time,
Richard
