Audit objectives are the specific purposes or goals that the customer or the certification body wants to achieve through the audit. They define what the audit intends to accomplish and provide the basis for planning and conducting the audit. Audit objectives may vary depending on the type, scope, and criteria of the audit, but they should be clear, measurable, and achievable.

Some examples of audit objectives for a third-party ISMS audit are:

Assess conformity with ISO/IEC 27001 requirements: This objective means that the audit aims to verify that the organisation’s ISMS meets the requirements of the ISO/IEC 27001 standard, which specifies the best practices for establishing, implementing, maintaining, and improving an information security management system. The audit will evaluate the organisation’s ISMS documentation, processes, controls, and performance against the standard’s clauses and annex A controls.

Confirm sites operating the ISMS: This objective means that the audit aims to confirm that the organisation’s ISMS covers all the relevant sites or locations where the organisation operates or provides its services. The audit will verify that the scope of the ISMS is accurate and consistent with the organisation’s context, objectives, and risks.

The other phrases are not audit objectives, but rather:

Evaluate customer processes and functions: This is not an audit objective, but rather a possible audit criterion or a requirement that the organisation’s processes and functions should meet. The audit criterion is the reference against which the audit evidence is compared to determine conformity or nonconformity. The audit criterion may include ISO/IEC 27001 requirements, customer requirements, or other applicable standards or regulations.

Fulfil the audit plan: This is not an audit objective, but rather a task or an activity that the auditor performs during the audit. The audit plan is a document that describes the arrangements and details of the audit, such as the objectives, scope, criteria, schedule, roles, and responsibilities. The auditor should follow and fulfil the audit plan to ensure that the audit is conducted effectively and efficiently.

Determine the scope of the ISMS: This is not an audit objective, but rather a prerequisite or an input for conducting the audit. The scope of the ISMS is the extent and boundaries of the information security management system within the organisation. It defines what processes, activities, locations, assets, and stakeholders are included or excluded from the ISMS. The scope of the ISMS should be determined by the organisation before applying for certification or undergoing an audit.

Review organisation efficiency: This is not an audit objective, but rather a possible outcome or a result of conducting an audit. The organisation efficiency is a measure of how well the organisation uses its resources to achieve its goals and objectives. The audit may help review and improve the organisation efficiency by identifying strengths, weaknesses, opportunities, and threats in its information security management system.
