This is network security design group assignment, my part of the assignment is to write about the roles of security devices. I supposed to used devices correctly with security technologies and stated clearly role of devices in diagram along with configurations. I have attached the diagram and other document I have on this project so far, please I need a tutor with knowledge in computer Networking to help me with this project. All devices need to be a cisco devices and paper needs to be in APA format and references as well. Please approach the question using this rough draft below:

Roles of Security Devices for WWTC: I will divided the network design into five layers and described the roles of security devices in each layer.

1. Physical layer: Door locks, Smart card, HVAC, CCTV, Guards, Remote backup facilities and etc.

2. Roles of devices for ISO layer 2: Switches will be needed

3. Next layer is securing ISO level 3: Routers will needed and VPN

4. Firewall and distributions layer: I will use the Cisco ASA 5500 corporate firewall and NIDS

5. finally, I will talk about how we can use servers or radius serves to secure assets on WWTC network.
