We're currently using the Symantec Management Platform 7.1 SP1 with all of the solutions installed.  Our Security Team is requiring us to change our setup to use SSL.  To my understanding, a certificate would be needed to use SSL but I am a bit lost as to where it needs to be.  I understand the Notification Server would require a certificate but do the Site Servers need one as well?  We're setup as a hierarchy with four Notification Servers on different subnets, each subnet also has a Site Server.  We will be rearchitecting our environment in December to reduce the number of NS to one with four Site Servers.
