Ok, so I also use RealVNC that is constantly listening on a port for a connection. Isn' t this just as vulnerable?

Truthfully, if your program doesn't have things like buffer overflow vulnerabilities, it's not that big a threat. After all, that's how any server application runs, right?

I am using a function library for the TCP connections that was written in C++.
I know that C++ is notorious for buffer overflow. I do not know C++. what do you think?
