We assume that the developers attending the JS secdev course:
    are familiar with the JS language and with XOX
    understand the HTTP protocol and HTML
    are familiar with basic security features of an enterprise application (authentication, authorization, the concept of a session)
    have XOX and a suitable IDE installed on their laptop (labs desktop)
