Technical System Landscape
Use
The SLD contains information about your system landscape that is relevant for system management, business processes, and various application areas. In certain situations, systems that are accessible externally form business scenarios with internal back-end systems. These scenarios can involve the SLD. In this case, the SLD contains information about both external and internal systems.
For security reasons, place the SLD server behind the firewall, and configure the firewall for RFC and HTTP connections. We recommend that you secure these connections by means of VPN or SNC.
The figure below illustrates the recommended network topology for the SLD server.
