Final answer:
The most effective method to demonstrate compliance with cybersecurity protocols for a global finance company is to engage a third party for external attestation. This offers objective validation and can be more persuasive to stakeholders than internal measures.
Step-by-step explanation:
To demonstrate the effectiveness and compliance of a global finance company's cybersecurity protocols, the most effective method would be engaging a third party for attestation. Although forming an internal audit committee, performing an internal compliance review, and initiating company-wide cybersecurity training are beneficial practices, they may not provide the same level of objectivity and credibility as an external audit. Engaging a third party would offer an independent verification of the company's cybersecurity practices, which can be particularly persuasive in demonstrating compliance to stakeholders.
Reference to establishing independent statutory bodies, as in point 10, suggests that an externally validated compliance process is trusted. This external validation process can be even more credible when it's conducted by a specialized cybersecurity firm. They can provide expertise, demonstrate compliance with the latest industry standards, and offer reassurance through certifications or reports that internal measures alone cannot match.
