Shared Applications in Heterogeneous Network Environments

Abstract

This contribution describes the basic measures that are associated with the secure sharing of applications in general heterogeneous network environments (e.g. the Internet The first section of this contribution explains the basic ways and means of securely connecting information systems (e.g. packet filters, applications gates, etc.) The second section is devoted to the secure sharing of applications. The solutions discussed within it are based ion the tight integration of three fundamental pillars, or technical components. These are, access portals, address book services, and the so-called “Public (electronic) Key” infrastructure. The mutual inter-combination of these technical elements allows the secure sharing of various applications that support the standard interface on the basis of HTML and XML.
