week 4 assignment

 
Using the scenario from the Week One assignment, write a 2- to 3-page business memo to the CIO of your organization detailing security recommendations. Include a Visio® diagram illustrating your security model and any areas of concern. Be sure to follow APA standards for a business memo.
Referencing your prior week’s infrastructure (specific) choices, use the “Understanding Cloud Security” guidance in Ch. 12 of the Cloud Computing Bible to think about one or two additional recommendations that you would make to improve security.
Incorporate into your memo the inherent security concerns for each area:

Service: What service to use (SaaS, PaaS, etc)? This is based on your Week One decision.
Design principles: To what standards do you need to adhere? (use Ch. 14, Amazon Web Services for Dummies, as a reference) This is based on your Week Two decision.
Security concerns: What virtualization security concerns do you have? This is based on your Week Three decision.

If you don’t have access to information about your organization’s network, try meeting with the network manager to come up with some ideas. If this is not possible, use the following scenario:

Internal Exchange 2003 server – this is a physical server
Internal CRM system – this is a virtual machine
Internal ERP system using SAP ERP 6.0 – this is a physical server
Internal File server using 1.2 TB of data – this is a virtual machine
(2) Internal SQL Servers used for business intelligence – (1) server is virtual and (1) server is physical

The network has the following characteristics:

A WAN with (4) connected sites – (3) distribution centers, and a corporate office.
Each site is connected via a 100 Mbps MPLS WAN and has a single T-1 for a failover connection.
The datacenter is centralized at one of the distribution centers.
