If this is truly a home network with trivial data on it, you are probably pretty safe.
Safe from what? This is bad advice and makes assumptions that are not based in fact.

The simple truth is that everyone is at some level of risk, irrespective of being corporate or a home user. As well, data is irrelevant (in the context of this discussion mind you). What is relevant is that you have a machine with an internet connection. If you're vulnerable, the probability is conservatively moderate (some may argue 'high') that you'll be exploited.

At the least your machine will get compromised and then left alone. Somewhere in the middle of the scale your machine may become host to a trojan/worm/virus, etc. At the other far end of the spectrum your machine may be used as a jump box or zombie for any number of purposes.

Again, your net worth, public profile, or business status have zero to do with the common, everyday attacker's choice in victimizing your computer. This notion of personifying computer intrusion is non-sense and just plain silly. Get real- your computer is just another IP address that someone is feeding into their point-and-click exploit tool. They don't even care if you're running the right OS for the exploit...

Follow OverdueSpy's advice - he's dead on in what he wrote- and layer your defenses. Be responsible and build up a defense-in-depth posture. Use a firewall, a secure/reliable vpn software, anti-virus, etc.

Relying on any one safeguard gives you a false sense of security which is only marginally better than no security. Worse, thinking your safe because you're running a "home network"...that's just asking for it.
