Before assigning sensitivity levels to information it is MOST important to:

Recovery Time Objectives (RTOs) are related to business continuity and disaster recovery, not directly to the initial process of defining information sensitivity levels.

Defining the information classification policy establishes the fundamental rules, criteria, and procedures for how an organization will categorize its data based on sensitivity and business impact. This policy is a prerequisite, as it sets the guidelines that inform how sensitivity levels will be assigned, ensuring consistency and alignment with organizational objectives.

Conducting a sensitivity analysis is an action performed *after* the classification policy is defined, as it uses the policy's criteria to assess and assign actual sensitivity levels.

Identifying information custodians is important for data governance and accountability, but the overarching policy framework for classification must be in place before specific custodians can effectively manage data sensitivity.
