Design improvements to the network infrastructure that improve security to electronic mail, and protect against intruders and malicious software. Revise the original Visio diagram to depict any changes you propose to make. Summarize your recommendations for change in a MSWord document.
The following questions are useful to you while you are making additions to your design. You should think about them while you are revising your diagram and summarizing your recommendations. Please do not provide answers to them as part of your deliverables.
1. Have I uncovered additional vulnerabilities since Milestone 2?
2. Does the redesign provide defense in depth?
3. Will the new secure network architecture maximize accessibility for wireless devices while still providing an appropriate level of security for a payment processing system?
4. What types of encryption are most effective and where should they be utilized?
5. What is the impact of each change on authorized users?
Your diagram should contain any revisions to the original network infrastructure that are required to improve security.
