This is a Hands-on project from the book named Cissp guide to security essentials(chapter - 1). please help me with this question.

In this project, you will design a new network infrastructure for a five-hundred-employee law firm. The design of the network should incorporate several elements that demonstrate a defense in depth architecture.

The design of the network should incorporate protection against the following threats:

>Malicious software

>Phishing

>Spam

>Leakage of intellectual property

>Non-company-owned devices on the internal network (bring your own device, or BYOD)

>Rogue access points

For each type of threat, indicate the control or features in the architecture that reduces or eliminate the threat.

This project is not so much about network technology as it is about the concept of defense in depth. Do now worry about whether you have incorporated the latest or the most precisely correct technologies in your design.
