Purpose: The purpose of the Infrastructure Diagram template is to document the physical infrastructure of the enterprise, which includes but is not limited to databases, wires, firewalls, computers etc.
Core concerns: The Infrastructure Diagram enables you to model your organizations infrastructure including: Computer Categories, Computers, Firewalls, Printers, Networks, Connection Points, Peripherals, Locations, Information Systems, System Components, Databases, Network Connections, Object Dependencies, Technology Domains, Technology Capabilities and Technology Components.
The models below exemplify how you would construct this type of diagram:
Relation to other templates: The Infrastructure Diagram template should not be used to document logical architecture, as the connections available in an Infrastructure Diagram are predominately geared towards documenting physical information about IT infrastructure. The Infrastructure Diagram can through its components be linked to other architectural diagrams such as the Application Architecture Diagram, and the data they contain. This way, if a firewall is breached, you would be able to very quickly identify what data has been vulnerable.
Properties and metadata: The Infrastructure Diagram can for example retain the following information:
- A description of the diagram
- Link to the owner of the diagram
- Link to the one responsible for the diagram
- Audits (auto generated information regarding its current state and access rights)
- Associated documents, diagrams and other objects
- Inherent Risk detailing risk considerations
- Governance information detailing information about the published diagram and who has been involved in the approval of the diagram
The above picture shows the properties dialogue window for the Infrastructure Diagram, where you can view and edit the diagram’s properties in QualiWare Lifecycle Manager.
