Explanation
Performing a gap analysis is the first step to ensure the security policy framework encompasses the new business model because it is a process of comparing the current state of security policies and controls with the desired or required state. A gap analysis helps to identify the strengths and weaknesses of the existing security policy framework, as well as the opportunities and threats posed by the new business model. A gap analysis also helps to prioritize the actions and resources needed to close the gaps and align the security policy framework with the new business objectives and requirements. Therefore, performing a gap analysis is the correct answer.
