1- Which is the best approach to be used during risk assessment between Asset based and Processed approach?
Answer: First it is important to understand that ISO 27001 does not prescribe an approach to perform risk assessment, so you can choose the approach that better suits your needs.
Asset-based risk assessment is easier to perform, while the process-based risk assessment can provide you a more understandable context to identify and evaluate risks.
