Which of the following documents BEST describes the manner in which a security assessment will be conducted?

A BIA identifies which systems and processes are critical to operations, defines acceptable risk levels, and establishes the criteria that shape how a security assessment is structured and performed. It is the foundational document that dictates assessment depth, sequencing, and focus areas based on business impact priorities.

A Statement of Work (SOW) is a contractual document specifying deliverables, timelines, and payment terms for a project engagement but does not define the risk-based methodology or priorities that govern how a security assessment is conducted.

A Service Level Agreement (SLA) defines performance expectations and availability guarantees between a service provider and client and does not describe how security assessments are carried out.

A Master Service Agreement (MSA) establishes overarching legal and commercial terms governing a business relationship and does not prescribe the procedures or priorities for individual security assessments.
