A leading UAE-based financial institution relied on a strict dual-control "maker-checker" architecture to manage sensitive consumer and commercial finance workflows. During an internal security assessment, a critical Broken Access Control vulnerability was identified that threatened this foundational framework. While the application successfully verified user identity at login, it lacked crucial server-side validation during individual function executions.

To restore absolute integrity to the dual-control environment, SISA delivered a prioritized remediation strategy that enforced robust server-side authorization and request ownership checks. Following the deployment of these structural logic fixes, comprehensive validation was performed to guarantee the vulnerability was neutralized. Furthermore, automated security tests were seamlessly integrated into the development pipeline to continuously inspect parallel approval systems for hidden authorization flaws. By closing this critical gap, the institution successfully minimized its exposure to unauthorized data manipulation and strengthened the governance of its core identity layer.
