BIA for ISO 27001

Answer:

First it is important to note that BIA is not required by ISO 27001 and this approach will only help to identify which processes are critical to the organization concerning availability, and for information security you also have to consider the loss of confidentiality and integrity.

To perform BIA I suggest you to take a look at the free demo of our ISO 22301 Business Impact Analysis Toolkit at this link: https://advisera.com/27001academy/iso22301-business-impact-analysis-documentation-toolkit/
