CBS-1 Retail & Digital Banking Access

Introduction

Retail and digital banking access is a foundational service for modern financial institutions such as CIMB Bank. This service enables customers to securely log in, view account details, transact funds, onboard digitally, and interact with support services through online and mobile platforms.

Operational resilience standards, including Bank Negara Malaysia’s 2025 Operational Resilience Discussion Paper, emphasize that dependency mapping is critical to understanding how people, processes, technologies, and third parties interact to sustain service delivery under stress.

Mapping dependencies ensures that weak points — whether human, technical, procedural, or external — are identified, monitored, and mitigated.

In this chapter, we map the key dependencies of the Retail & Digital Banking Access service to support risk assessment, continuity planning, and recovery strategies.

Dependency mapping for Retail & Digital Banking Access at CIMB Bank provides critical insight into how sub‑services rely on people, processes, technology, and external partners. By documenting these interdependencies, the bank gains visibility into potential single points of failure, risks from third parties, and areas requiring strengthened controls or redundancy.

This structured approach to resilience aligns with operational risk standards and guidance, such as in Bank Negara Malaysia’s 2025 Operational Resilience Discussion Paper, which highlights the need to understand cross‑cutting dependencies and their impact on service continuity.

Ultimately, a comprehensive dependency map enhances preparedness, informs recovery planning, and supports more resilient digital banking operations — ensuring customers can access core banking services even under stress.
