At the end of textbook (attached) on page 385, the author mentions several “encouraging security architecture developments”:      

• The  Open Group has created an Enterprise Security Architect certification.  One of their first certified architects has subsequently created a few  enterprise security reference architectures.    
• The SANS Institute hosted three “What Works in Security Architecture” Summits.    
• The IEEE initiated a Center for Secure Design. The Center published a “Top 10 Design Flaws” booklet.   
• Adam Shostack published  Threat Modeling: Designing for Security, and renown threat modeler,  John Steven, has told me that he’s working on his threat modeling  book.    
• Anurag  Agrawal of MyAppSecurity has been capturing well-known attack surfaces  and their technical mitigations within his commercial threat modeling  tool, “Threat Modeler.” 

Choose  2 or 3 three items from the list above and provide an update to their  development status.  Make sure you provide some background on your  selection and then provide the update of the development.

 Answer  the questions with an APA-formatted paper with in-text citations (Title page, body and  references only).  Your response should have a minimum of 600 words. A minimum of two references are required.
