Question 15

A multinational organization operating a complex Service-Oriented Architecture (SOA) for its core financial services faces an abrupt and significant shift in its operating environment. New, stringent governmental regulations have been enacted mandating strict data localization for all customer financial information, requiring that data be stored and processed exclusively within specific national borders. This mandate directly conflicts with the company\'s existing SOA design, which leverages distributed cloud services and geographically dispersed data centers to optimize performance and resilience for its global clientele. The security team must now adapt its strategy to ensure compliance and maintain service integrity without compromising existing security postures or significantly impacting user experience. Which of the following strategic adjustments best addresses this multifaceted challenge, reflecting a critical need for adaptability, leadership, and problem-solving within the SOA security framework?
