Bill, It is not an oversight. Asset discovery has two main purposes: firstly, find all assets that can be managed by bigfix. secondly, generate custom network scan report by using wizard. If you are using asset discovery to achieve goal one, then include or exclude 443 doesn’t help, since there is no logic inside importer to detect status for port 443, or we can say, the only port that will influence importing result will be 52311, which is the udp port that bigfix agent is using. If you would like to use wizard to generate a custom network scan report, then you could adjust ports you want to include for scanning. Note, due to different network firewall settings, the sniffing packages that target to 443 may be blocked.
