    This should be achievable in 19.0.0.3 and later.



    Liberty 19.0.0.3 (and later) only accepts client certificate details in private/extension


    headers from an explicit list of trusted proxies. The "trustedSensitiveHeaderOrigin"


    attribute of the "httpDispatcher" configuration element names the peers these headers


    are trusted from.



    More details on "trustedSensitiveHeaderOrigin" is available here:


    https://www.ibm.com/support/pages/potential-websphere-application-server-problems-when-deployed-behind-websphere-aware-proxy-server



    Requiring (1-way) TLS for connections to the application satisfies the tampering concern.



    It is also possible to require TLS mutual authentication at the transport layer (between IHS and Liberty),


    which further limits what software/users from the trusted proxies can send requests to the server. This


    is accomplished via the "clientAuthentication" attribute of the "ssl" configuration element.
