Network Structure (Level 3)

  • Which network levels (production network, office network, Internet, etc.) should be established or respected?
  • Which zone concepts (i.e. DMZ, island network) are to be used?
  • Which technology for workstation clients should be used (web clients, fat clients, thin clients, virtual desktops, etc.)?
  • Which hardware and network redundancy is needed?
  • Is additional hardware required in order to ensure data security?
  • Which cross-system data flows and data flow directions are expected? What is the leading system?
  • What actions should be taken into account to bridge larger distances between subnets or individual systems?
  • Are there any requirements or known restrictions on bandwidth and latency?
  • Are interfaces to other systems outside the ISA functions (i.e. weather information from the Internet) required?
