1 - I am filling the Inventory of assets as per the ISO 27001 toolkit template. I tried to access to the "How to handle Asset register according to ISO 27001 link but unfortunately couldn't as data was not found.
2 - The problem I am having is that, from the different assets categories, e.g. people, applications and databases e.t.c. I do not know if there is a certain procedure to follow to fill the categories in the given template.
Answer: No, there is no such procedure to be followed. I suggest you to click the 'Checklist of assets' sheet, which contains examples for each category, to guide you which category you should apply to your asset.
