Mike,
we are all concerned about privacy, hackers, etc.
But if you are in a corporate environment, please understand the position of
the sys admin (if if she may be a moron ...). She is responsible for the net.
Do you understand what is on that net ? Accounting ? Sales ? Atomic bomb lab ?
Will you have access to Internet from within the lan ? Will the sys admin let
you out ? Do you want to risk "digging a tunnel" to fool him ?
You should openly ask him if you can plug in your pc. You will have to obtain
an IP address on that lan, manually or dynamically (DHCP) - with or without
sys admin knowledge ?
Get an OK from him first. 
Then learn about desktop security - Fedora has a nice gui firewall, just accept
the defaults (but check off SSH service port) and you are safe.
There are some additional steps you can take - just read a Red Hat manual on
security.
