Short answer, no, there's no one way (or two ways) to ensure that your network/computer will never be hacked (at least, not yet). You can make it exceedingly difficult by ensuring that your PC(s) have no remote access, you can restrict PC's/user accounts from having read/write access. etc... But, there are also software/OS vulnerabilities that can circumvent your own security protocols, which is why we get hotfixes for Software and OS's to plug those gaps. Plus, it also doesn't take into account an inside force. Even if the machine is only accessible physically, you can never be 100% sure that everyone who enters your building/house, or is employed w/ you, isn't working for another side, or, won't get pissed off over something the company did, and decide to exact some revenge.
