BIA ISO 22301

Welcome friends,
I have a problem in BIA analysis. Analyzes an exemplary process: customer service at the financial point - stationary. The process is carried out, for example, in 10 locations in the country. In case of threats related to a specific point, e.g. a fire, only one facility loses. However, in the event of a ransomware attack or a complete failure of our ISP, none of the 10 work. What data related to the interruption of customer service should be taken into account in the analysis? Analyze the entire department or a single stationary service point? Please help!

Please note that when performing BIA your focus is on the impact of interruption, considering the worst-case scenario, not on what can cause it.

Considering that, you should perform a BIA considering the interruption of customer service at all service points. During this BIA, you can organize the required resources for recovery according to each individual service point for better understanding of individual needs.

The identification of which risks can cause the interruption is used in another phase of the process (risk assessment, which should not be mixed with BIA), when you define controls to treat relevant risks (e.g., firefighting system, antimalware software, information backup, alternative providers, etc.)
