Firstly they would have to get through the firewall. A good firewall will not allow connections that were not initiated from within the system anyway. Secondly the intruder would need to crack the root password and only then would they be able to modify the code of the firewall.
If you want a secure system make sure your firewall does not allow any connetions in the first place unless you need them. i.e. if you run an Internet server you would only need port 80 open for connections. Ensure that your root password is fairly complex so that it will be very difficult to crack.
