What is a Trust Architecture?
The fundamentals of a Trust Architecture involve defining how your organization works. Once that is accomplished, you must decide:
Who: Who or what do you trust?
What: What is the extent of that trust?
Why: For what purpose has trust been assigned? (Authorized or assigned?)
When: Over what periods is that trust authorized? (or assigned?)
Once these factors are defined the processes to manage and monitor them can be put in place.
