I submitted the project for critiquing and this is what my professor replied:

I looked at your network diagram, and this is a good start, but the capstone is cybersecurity capstone.

Network configurations missing include:

Designated core routers and/or edge routers
Network Subnets with appropriate IP address assignments. Ip configuration of devices is not necessary.
Server roles (AD, DNS, DHCP, etc.)
Security appliances (host devices and network devices)
Naming conventions

When completing your document, please include company information (profile), the ERD diagram (relational database structure for the protected records), company information, and rationale for security structure using the NIST framework. Can you expand on what you already done?
