SECURITY WITH A FINANCIAL CONSEQUENCE
A cyber event can become a customer, liquidity or operational problem
Financial institutions depend on digital channels, payment networks, identity platforms, core systems and external service providers. A weakness in one part of this environment can affect customer access, transaction confidence or regulatory accountability.
“A control is dependable only when it holds during real operating pressure.”
Customer channels
Mobile banking, online portals, payment journeys, applications, APIs and contact centres.
Financial processing
Core systems, payment engines, policy platforms, trading services, settlement and reconciliation.
Enterprise operations
Identity, workforce technology, cloud platforms, data services and administrative systems.
External ecosystem
Fintech partners, processors, cloud providers, market infrastructure and specialist suppliers.
PROTECT THE COMPLETE TRANSACTION
Security must hold before, during and after money moves
01
Identify
Is the customer, employee, system or partner who they claim to be?
02
Authorise
Is the person or system permitted to initiate the requested action?
03
Validate
Do the amount, beneficiary, account, device and context make sense?
04
Execute
Is the transaction protected against manipulation while it is processed?
05
Record
Is there a complete and trustworthy record of the action?
06
Reconcile
Can discrepancies, duplication and unauthorised changes be identified?
07
Investigate
Can security, fraud and operations teams reconstruct what happened?
THE ACCOUNT IS A HIGH-VALUE BOUNDARY
Protect every route that can change financial access
New customer onboarding
Identity verification, document checks, fraud screening and account creation controls.
Customer account
Access, money movement, stored information and service requests converge within the account.
Sign-in and device registration
Authentication strength, device binding, session management and trusted-device controls.
Account recovery
Reset workflows, identity re-verification, fraud detection and recovery-path controls.
Beneficiary and payment changes
Approval workflows, confirmation delays, fraud signals and authorisation controls.
Contact-detail updates
Re-authentication, change notifications, monitoring and reversal controls.
Customer-support intervention
Agent access controls, verification procedures, action logging and override governance.
Authentication must cover customers, employees, third parties and system-to-system communication. FFIEC authentication and access guidance provides the relevant framework for financial institutions.
Assess Identity and Account ControlsPRIORITY EXPOSURES
Risks shaped by access, transactions and interconnected services
Account takeover and transaction fraud
Compromised credentials, manipulated recovery processes or weak transaction controls can lead to unauthorised access and financial loss.
Ransomware and operational disruption
An incident can affect customer access, payment processing, claims, trading, lending and internal decision-making.
Privileged access misuse
Administrator, developer and supplier access may provide broad control over sensitive systems.
Application and API weaknesses
Authorisation and workflow flaws can expose customer data or financial functions.
Third-party concentration
Several critical services may depend on the same provider or technology platform.
Data integrity failure
Unauthorised changes can affect balances, decisions, reports, models and regulatory records.
CUSTOMER-FACING SECURITY
Test the financial workflow, not only the interface
Who can perform the action?
Validate authentication, authorisation and session controls.
Can the workflow be manipulated?
Test transaction order, approvals, limits and business rules.
Can another customer's data be reached?
Assess object-level access and account separation.
Can automation abuse the service?
Review rate limits, account attacks, enumeration and resource exhaustion.
Can sensitive changes be detected?
Confirm monitoring for beneficiaries, contact details, devices and access methods.
Can the event be investigated?
Verify that meaningful actions create complete, protected records.
CONNECT THE AVAILABLE EVIDENCE
Fraud and security teams need a shared view of significant events
Customer and transaction signals
Security and technology signals
Operational context
Shared investigation and decision
Correlate identity, transaction, device and system activity before determining containment, customer action, reporting and recovery. Cybersecurity monitoring supports but does not replace financial crime or fraud-management controls.
KEEP CRITICAL OPERATIONS WITHIN TOLERANCE
Map the service, test disruption and improve the response
Critical financial operation
A critical operation should be defined by the service delivered to customers or markets, rather than by one application or infrastructure component.
Examples
01
Map
Identify systems, data, people, facilities and third parties supporting the operation.
02
Set tolerance
Define how much disruption the operation can withstand.
03
Test
Exercise severe but plausible scenarios across technical and business teams.
04
Improve
Address findings, update dependencies and validate completed remediation.
The Basel Committee's operational resilience principles connect resilient ICT and cybersecurity with protection, detection, response, recovery and regular testing. Basel Committee principles for operational resilience provide the relevant framework.
Assess Your Operational ResilienceDEPENDENCY BEYOND THE ORGANISATION
A strong supplier review must consider the combined exposure
Individual supplier risk
Concentration risk
Responsibility remains with the financial institution
Contracts and supplier reports support governance. They do not remove the institution's responsibility to understand, monitor and respond to outsourced-service risk.
CONNECTED FINANCIAL SERVICES
Innovation expands the service boundary
Cloud service providers
Infrastructure, platform and software services hosting core financial systems and data.
Financial institution
The accountable entity responsible for customer outcomes and regulatory obligations.
Payment processors
Transaction routing, clearing, settlement and payment network connections.
Fintech partners
Embedded finance, open banking, lending and product-layer integrations.
Identity and verification providers
KYC, biometric, fraud-scoring and authentication services.
Data and analytics services
Credit bureaus, market data, risk models and reporting platforms.
Each connection should have a defined purpose, limited access, secure data exchange, monitoring and a clear exit process. Reviews should account for the service provider and any material subcontractors.
Assess Your Financial Technology EcosystemTRUST THE DATA BEHIND THE DECISION
Protect financial information against unauthorised change
CONTROL HIGH-IMPACT ACCESS
Every privileged route needs an owner and a record
| Access type | Business need | Approval | Authentication | Monitoring | Removal |
|---|---|---|---|---|---|
| Workforce administrators | Defined system scope | Manager and security | MFA required | Session recording | Role change or exit |
| Developers and engineers | Production access controls | Change board | Strong authentication | Code and deploy logs | Project end or transfer |
| Third-party support | Specific service only | Formal request | Verified identity | Activity monitoring | Task completion |
| Emergency access | Break-glass procedure | Senior approval | Dual authorisation | Full audit trail | Post-incident review |
For each access type, define why the access exists, who approves it, how the user is verified, which actions are monitored, when the access expires and how emergency use is reviewed.
Review Privileged AccessCONTROL CHANGE THROUGHOUT PROCESSING
Protect critical systems against unauthorised modification
01
Request
Document the purpose, affected service and accountable owner.
02
Review
Assess security, operational and transaction-integrity impact.
03
Approve
Use appropriate separation between request, approval and execution.
04
Implement
Protect deployment access and maintain a complete record of the change.
05
Validate
Confirm processing, data and monitoring before closing the change.
RBI's IT governance directions include controls around access, audit trails, critical applications and protected data transfer for applicable regulated entities.
EVIDENCE THAT CAN WITHSTAND REVIEW
A written control and an operating control are different things
Control objective
Regulators, auditors, customers and internal risk teams may examine the same control from different perspectives. Evidence should show what the control is intended to achieve, who operates it, how it is monitored and what happened when it failed.
DECISIONS UNDER TIME PRESSURE
Coordinate containment, customer impact and reporting
Establish facts
Protect customers and operations
Coordinate obligations
Recover and learn
ASSURANCE WITH CONTEXT
