To provide maximum security, in the Compass mode, Application Connector uses the TLS protocol with Client Authentication enabled. As a result, whoever wants to connect to Application Connector must present a valid client certificate, which is dedicated to a specific Application. In this way, the traffic is fully encrypted and the client has a valid identity.
By default, the TLS certificate verification is enabled when sending data and requests to every application. You can disable the TLS certificate verification in the communication between Kyma and an application to allow Kyma to send requests and data to an unsecured application. Disabling the certificate verification can be useful in certain testing scenarios.
