The AD In Depth report shows how the citations are broken down into mandates. There are only two mandates associated with this citation, not three like you mentioned. I am going off of version 3.2. The first mandate is to "assign a risk ranking to the discovered vulnerabilities." which would map to control 11940 (Rank discovered vulnerabilities.) The second mandate is "Establish a process to identify security vulnerabilities, using reputable outside sources for security vulnerability information." which is mapped to control 12135 (Subscribe to a threat intelligence service to receive notification of emerging threats.) These are the correct mappings for what the citation says. I am not sure where you got the third mandate from. As for the placement, you would conduct a vulnerability scan in order to identify vulnerabilities and then rank those. This has nothing to do with checking with outside sources. That is a completely different mandate.
Control 07032 sits under 00896, because installing patches is a part of the patch management program. It cannot sit at the same level as that, then there would not be a hierarchy. We put patching under the change management process. although it could possibly be with preventative maintenance.
We are currently in the process of conducting a review of our entire hierarchy. While looking at the placement of controls, we will take your comments into consideration.
