Explain the difference between physical network segmentation and microsegmentation as they relate to cloud security. Explain what it means to implement a zero trust security strategy. Explain how microsegmentation can support a zero trust network 

  Using APA 6th edition style standards, submit a Word document that is 3-4 pages in length (excluding title page, references, and appendices) and include at least two credible scholarly references to support your findings. 

 Include the following critical elements in your essay: 

I. Physical Network Segmentation vs. Microsegmentation: Briefly describe each networking environment with regard to cloud security. Describe the difference between these two networking approaches as it relates to network security. 

II. Zero Trust Security. Explain the concept of Zero Trust Security. How is this model different from conventional security models? How does this model support ubiquitous security in a cloud environment? 

III. Microsegmentation for Zero Trust Security: Explain how microsegmentation topology provides the foundation for implementing the Zero Trust model. Why do modern organizations need to consider implementing a Zero Trust security approach?
