and I follow this complete my application 。 all SSL protocal function realized in private box and socket communication realized in public BOX.
now I don't konw how to do some test to prove the application is secure.anyone who can give me some advice?
Thanks！

Start with the mbed uVisor documentation and the linked architecture picture, then review how the application separates SSL functions in the private box from socket communication in the public box. The issue does not name files or tests; done would require a documented, project-approved way to evaluate and demonstrate the application's security.
