I would recommend using amap to see about getting a fingerprint of the
application used on these ports if possible and/or contacting your firewall
team to check the configs and see what these services are for. The IANA
lists of port to application mappings are general guidelines, not explicit
sets of what the application actually is. There's no law that says you have
to run ms-term-serv on port 3389 :) You should be concerned about more than
just the 1029 and 1032 ports. I know of no valid security or business reason
why you would want to allow random people on the internet to attempt
terminal connections to your internal machines... That's what VPN's are for.
