CBS-12 Third-Party / Outsourced Service Management

Scenario testing for CBS-12 focuses on validating Metrobank’s ability to maintain critical business services when faced with severe but plausible disruptions.

These tests are designed to simulate real-world operational challenges, including cyber threats, vendor failures, and regulatory compliance issues, to ensure response and recovery measures can sustain services within approved impact tolerances.

Integrating cyber and ICT risk considerations is critical, as these risks often amplify third-party dependencies and service continuity challenges.
