[OR] [MBT] [E3] [CBS] [12] [SuPS] Identify Severe but Plausible Scenarios

CBS-12 Third-Party / Outsourced Service Management

Severe but plausible scenarios (SbPS) are hypothetical events that pose significant threats to the continuity of critical business services, yet remain within the realm of realistic possibility.

In the context of Metrobank's CBS-12 Third-Party / Outsourced Service Management, these scenarios help identify vulnerabilities across vendor management, contract oversight, service monitoring, continuity planning, regulatory compliance, and incident response.

By testing the bank’s resilience against these scenarios, the organisation ensures that operational limits are understood, impact tolerances are maintained, and customer trust is safeguarded.

Table P5: Identify Severe but Plausible Scenarios for CBS-12

Sub-CBS Code	Sub-CBS	Severe but Plausible Scenario	Impact/Effect	Proactive Risk Management Action	Link to Integration of Cyber and ICT Risks
12.1	Vendor Risk Management	Major vendor suffers ransomware attack	Disruption of critical services supplied by the vendor, delayed transactions	Vendor due diligence, continuous monitoring, and cyber resilience assessment	Aligns with ICT risk management by evaluating vendor cyber controls and response capabilities
12.2	Third-Party Contract Management	Contractual dispute leading to service suspension	Potential breach of service level agreements, regulatory non-compliance	Periodic contract review, inclusion of continuity clauses, and legal oversight	Integration of contract and ICT risk mitigates gaps in service continuity obligations
12.3	Outsourced Service Monitoring	Multi-site outsourced service outage	Delay in transaction processing, operational downtime	Real-time monitoring dashboards, escalation protocols, and redundancy planning	ICT risk monitoring tools provide early alerts of outages and cyber anomalies
12.4	Service Continuity Planning	An extended power outage at a major outsourced data centre	Inability to deliver critical banking services within the impact tolerance	Business continuity plan activation, backup site switching, and staff readiness exercises	Cyber-physical integration ensures recovery plans address both ICT failures and cyber threats
12.5	Compliance and Regulatory Assurance	Regulatory audit uncovers non-compliance due to third-party practices	Regulatory fines, reputational damage	Periodic audits, compliance reporting, and training for vendors	Cybersecurity audits embedded in regulatory compliance processes
12.6	Incident Management and Response	Coordinated cyber-attack on multiple third-party systems	Data breaches, service unavailability, and reputational harm	Incident response plan, tabletop exercises, communication protocols	Direct link to ICT risk management ensures rapid containment and mitigation of cyber threats

Banner [Summing] [OR] [E3] Identify Severe but Plausible Scenarios

Identifying severe but plausible scenarios for CBS-12 enables Metrobank to systematically stress-test its third-party and outsourced service management processes.

Through this proactive approach, the bank strengthens operational resilience, ensures regulatory compliance, and integrates cyber and ICT risk considerations into everyday vendor and service management activities.

These scenarios are critical not as predictions, but as strategic tools to validate readiness, uncover vulnerabilities, and maintain uninterrupted service delivery even under extreme conditions.
