Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is D. Identify stakeholders.

SDLC and RMF

According to the NIST RMF, system categorization based on the system impact level determined by data types is the first step, but identifying stakeholders first is more practical as stakeholders and their needs and requirements drive everything. It determines which types of data are processed on the cloud.

  • Government departments and agencies can lookup data types specified in the NIST SP 800-60. However, the predefined data types in NIST SP 800-60 may not be applicable to private companies.
  • Moreover, what services are provided by the SaaS? ERP, CRM, email, or document repository services? Are there any applicable legal or regulatory requirements? Identifying stakeholders helps in determining data types.

I designed this question based on a real case from a friend, also a CISSP. He is in charge of the security plan for the SaaS project.
