Which of the following is the MOST important factor when designing information security architecture? 

Answer options:

A. Technical platform interfaces
B. Scalability of the network
C. Development methodologies
D. Stakeholder requirements

D

The most important factor for information security is that it advances the interests of the business, as defined by stakeholder requirements. Interoperability and scalability, as well as development methodologies, are all important but are without merit if a technologically-elegant solution is achieved that does not meet the needs of the business.
