This services/port are already added with Application MS-SMS. So, you have to allow ms-sms application on the security profile in order to allow/identify WSUS 6.2 traffic.
Description: System Center Configuration Manager, formerly Systems Management Server (SMS), is a systems management software product by Microsoft for managing large groups of Windows-based computer systems. SMS provides remote control, patch management, software distribution, and hardware and software inventory.
Hope this helps.
For any existing application signature, you may look into this link ( search for existing application or port number): Application Research Center
It appears ports 8530 and 8531 have been removed again from app-id ms-sms as of 6/1/2018.
I contacted support and they confirmed this. Unfortunately, they could not provide a reason why. I ended up having to perform an application override for ms-sms to use ports 8530 and 8531 for my Windows Updates to work again.
