Hi guys
we have network, windows servers.

We have some users with mac on domain. We have realised some users use back to my mac to access there macs in office.

We have yubikeys for authentication as 2 factor and by them using this it has caused alarms for us

Is there anyhow we can turn that off? we don't have mac servers so cant deploy via that. anything on firewall?

We also think users may have team viewer on there desktop and connect from home. Only thing is we cant restrict team viewer as they support customers on daily basis and need team viewer.

For Back to My Mac, you may have to block all ports that it uses, but that can cause issues with other services.  You may be able to just block certain ports and sufficiently disable access.  I've never used back to my mac, so I can't tell you what you need to block.

Because of the way TeamViewer manages manages connections, it's probably less secure than Webex or GoToMeeting/GoToMyPC in the sense that the TeamViewer App automatically has a server instance running.  The quickest thing to do with that is to block it and switch to one of the other services for customer support.  I don't think they have a version that leaves that off.  The QuikJoin might be what you want to have them run instead, but, as I haven't used it before, I'm not sure whether it works for connecting to a normal TeamViewer ore QuickSupport sessions.

If you're an administrator with remote access to an admin account, you can use the built-in application firewall and block it.

/usr/libexec/ApplicationFirewall/socketfilterfw --blockapp <path>
