Security Question

If wrong forum please move

I have a Gateway program (written in Java by some company) which allows me to login to a business sever(not mine nor in anyway controlled by me).
Once logged in I receive data from this server into a VB Classic program (mine).
I can monitor the transmission between my program and the server using Wireshark, but the transmission is encrypted.
Since my program resides in one directory and the gateway in another directory, is there anyway to:"

1) Actually secure my system (client) from the server (e,g, client side cursor, or browsing my directories, or downloading info from my system) ??
2) Identify when or if any of these actions may (are) occurring?

Good question.
I don't have an answer, but hope to learn something here.

if you are communicating with the server using a protocol like http or odbc then your ports will only allow this traffic which precludes browsing your folders unless you setup an ftp server or were sharing through mapped drives, in which case you can control the access?

Thanks for responding.

For sake of argument, say the Java program which is run (by me) to start the Gateway program and link to the server contains (which I'm sure it does) a library of functions.
Could not one (or more) of these functions be called and executed from the server using http?

Bump: Looking for more input.
