ARD Access Logs?

Question

I have ARD 2.2 and I've been trying to figure out how to see whether someone is gaining access or not.
I see on the system.log this kind of showing --
Nov 6 09:30:17 username kernel[0]: ipfw: 5013 Accept TCP 202.125.171.59:2608 70.247.xxx.xxx:5900 in via en0
Nov 6 09:30:17 username kernel[0]: ipfw: 5013 Accept TCP 202.125.171.59:2611 70.247.xxx.xxx:5900 in via en0
["username" replaces the actual user; the "xxx.xxx" replaces original receiving machine's IP number]
Now, the thing is..., when I access it successfully and do whatever I'm going to do, it looks like this. And, whenever some other machine access the ARD port, it looks the same, but I'm not sure if they're really gaining access or just getting to the port. It looks the same with mine and with others.
I don't believe others are gaining access, because it doesn't really look like things are happening -- but how can I tell from the logs what is really going on?
Is there some kind of logging that says that not only has this [other] machine [i.e., computer] gain access to the port [which that is what it appears to be saying on the above log], but has also successfully started "controlling" the computer?
You see, on the one hand, I've gained control of the machine and on the other hand, I don't believe those other "port accesses" have gained access to the machine. But, what's different in the logs that shows me that?

I believe this is related, but my question is, what do the following lines in the System Log mean? Where is the ARD Access Log mentioned by Star Traveler?
