CBS-1 Deposit, Savings, and Current Account Services
Introduction
This chapter documents the mapping of processes and resources supporting CBS-1 Deposit and Withdrawal Services for Bank Islam.
Deposit and withdrawal services are foundational retail banking activities and are classified as important business services due to their direct impact on customers, financial stability, and trust.
In line with operational resilience principles, this mapping identifies people, processes, technology, third-party vendors, and dependencies that enable the service to be delivered within defined impact tolerances.
The mapping supports scenario testing, vulnerability identification, and recovery planning by making critical dependencies explicit.
