Proper network design provides for compliant security, not only isolating users and their traffic, but also preventing attackers from easily traversing a network.
Using Microsoft Visio or another online network diagramming tool, diagram the network that was analyzed in the Topic 1 “Quantify the System” assignment.
Then, create a diagram for a better approach for compliance, based on one of the following frameworks: PCI, HIPAA, NIST, or any other accepted framework.
Ideally, the network will be an Enterprise class consisting of 1000+ clients for various corporate departments, with 50-100 servers providing typical network services. The network infrastructure will be using Layer 3 switches and layered routing to provide separation of subnets.
Your diagram, at a minimum, should include the following secure network design elements: Firewalls, IDS/IPS, DMZ, Vlans, Border and Gateway routers, private IP addressing, Isolated Server Subnets, Network Access Control, and VPN concentrator.
