An ISO 27001 audit team is conducting an assessment of an organization\'s information security management system (ISMS). During the audit, the team encounters significant resistance from the IT operations department, with key personnel being uncooperative, providing incomplete information, and exhibiting a general lack of engagement. The Lead Auditor suspects this behavior stems from a perceived threat to their departmental autonomy or a misunderstanding of the audit\'s purpose, rather than a deliberate attempt to conceal non-compliance. How should the Lead Auditor best address this situation to ensure the audit\'s integrity and effectiveness while maintaining professional relationships?

Accepted Answer

Immediately escalate the issue to senior management, requesting disciplinary action against the uncooperative personnel to compel compliance.

Question 28

During an ISO 27001 audit of a financial services firm, the lead auditor is examining the effectiveness of controls related to asset management. The firm recently migrated its customer relationship management (CRM) system to a new Software-as-a-Service (SaaS) provider, a move intended to enhance scalability and accessibility. However, upon reviewing the organization\'s asset inventory and risk register, the auditor finds no mention of the SaaS CRM platform or any associated risk assessments pertaining to its implementation and ongoing operation.
