Confidentiality levels

Could you please inform  of the recommended confidentiality levels along with the best practice for setting these for the documents within ISO 9001, 22301 & 27001.
 

Answer:

Yes, sure. Commonly there are 3 confidential levels (and 1 Public level which means that everyone can see the information): Confidential (top level), Restricted (medium), and Internal use (lowest level). And from my point of view, the best practice for setting these for documents is to develop an Information Classification Policy.
