Key Risk Indicators (KRIs) are metrics used by organizations to provide early warning signs of potential risks, including unauthorized data disclosure. By monitoring KRIs, organizations can proactively identify vulnerabilities and take corrective actions before a risk materializes. This proactive approach is essential in minimizing the potential impact of data breaches.​

They are critical to the measurement and monitoring of risk and performance optimization. ​ISACA

While data backups (Option B) are vital for data recovery post-incident, they do not prevent unauthorized disclosures. An incident response plan (Option C) is reactive, focusing on responding after an incident has occurred. Cyber insurance (Option D) provides financial compensation post-incident but does not prevent the occurrence of data breaches.​

Therefore, implementing and monitoring KRIs is the most proactive approach to minimizing the potential impact of unauthorized data disclosure.
