Using what you have learned and researched about security architecture and engineering in this module, conduct in-depth independent research to learn more about the topic using the course materials and readings as a springboard. You will draft a memo recommending your approach for a security architecture and engineering model for the organization that you have been working with throughout the course.
Software Architecture and Engineering Models Memorandum:
Address your memo to your CEO and leadership, with coordination through the CIO. This memo will educate leadership on the importance of making the right software security decisions for the organization, so the memo will describe the software landscape and its applicability to the current needs of your organization.
The 5-7 page memorandum should accomplish the following:
Start by first researching the various security models, identifying key features, weaknesses, and targeted sectors and/or infrastructures. Then develop a short summary for each of the security models listed below and others that your research may uncover:
Bell-LaPadula
Biba’s Strict Integrity Policy
Clark-Wilson
Chinese Wall
Clinical Information Systems Security
Noninterference Security
Deducibility Security
Graham-Denning
Begin your memo with a short summary for each model, including a descriptive and evaluative paragraph with the following attributes:
The origins of the model- Who developed it? When was it developed? What was the context under which it was developed?
Main characteristics of the model- Details on the business, sector, and/or industry for whom the model was developed
Key features of the model
Weaknesses of the model
Targeted sectors/infrastructures
The summaries for each of the security models will complement your final memo and will document the security models and their attributes, providing support for your recommended approach that you illustrate in your memo. 
Please be sure to focus 2-3 pages on the reason for your model selection and the rationale.  
Your submission should include a cover page, abstract,  introduction, and conclusion with scholarly references in APA format at the end. Information on APA formatting
