Which type of documentation should the auditor examine first?

The auditor should first examine strategic documentation, such as the declaration of scope, objectives, and policies of the organization. This type of documentation sets the foundational context for the entirety of the Information Security Management System (ISMS). It articulates the organization's commitment to information security, including its objectives and the scope of its ISMS, which guides the direction of all subsequent policies and procedures.

By reviewing strategic documentation, the auditor gains insights into the organization's goals regarding information security, helping to establish whether the ISMS aligns with the overall business objectives. Understanding this framework is crucial for evaluating how well the organization manages and protects its information assets in accordance with its stated objectives and policies. It provides a roadmap for the more detailed analysis that follows, including risk management documentation and supporting procedures.

Strategic documentation is vital in aligning the audit process with the organization's mission and objectives, ensuring that the auditor can assess compliance and effectiveness thoroughly.
