People have asked if they could see examples of the two diagram types that are requested in the SRAQ.  Below are an example of each, with the key pieces of information highlighted.  (They are

Network Diagram Guidance:

Step 1: Identify the components that make up your system

  • What devices?
    • Servers, workstations, and printers (including hostnames and IP addresses)
    • Routers and firewalls
  • Where are those devices located?
      • Physically - IT Data Center, UCI building, AWS cloud, etc.
      • What network/sub-net does the devices sit on.
      • Are there any test environments used?
      • Are there any 3rd party networks that support your system?
        • cloud services, other non-UCI networks

Step 2: Group together devices and locations and draw out all components.

  • Components:
    • Servers, workstations, printers
    • Firewalls
    • Subnets
    • Data centers
    • 3rd party network
    • Test environments
    •  For better visibility you can color code UCI internal vs. UCI external components.

Step 3: Draw lines connecting different components together.

 

Example Network Diagram

The below example has key information highlighted. (This example is "based" on a real system, but the hostnames/IP addresses and some of the details were made up to protect the innocent).  Your diagrams may not look exactly like thesethis, but they it should convey the same level of detail and amount of information to aid in the review process.  The diagrams below were created using MS Visio 2010.  Stencils used were Basic Shapes, Network and Peripherals, Computers and Monitors, Data Flow Diagram Shapes.
