Windows 7: Is this secure?

Ok. PC#1 has a wireless connection to the internet. This connection only has TCP/IP 4 bound to the adapter, no file sharing or anything else. This PC has in addition, an ethernet card that is connected to PC#2 and has file sharing enabled with several shared folder between the two. PC#2 has no internet connection.

All connections are firewalled. Are my shared folder reasonably secure since my internet connection has nothing bound to it besides TCP/IP 4?



Thanks.

Secure. Just make sure inbound netbios and other incoming ports and are blocked in firewall and/or block all local servers.

Wise incoming ports to block = 135, 137-179, 445, 515, 593, 1433, 1434

Use AES encryption for wireless (WPA2) with a long random password.

If you run a server, your security is only as good as the serving app you're using.

Yep. As long as there is no bridging going on and your hardware firewalls are all up to date, there is no insecurities present what-so-ever.
