Network security with shared wifi
Posted on 2008-11-10
The people next door have just asked if they can use my internet access via wifi for a few months. Leaving the legal issue of my responsibility for their internet usage aside, my biggest concern is them being able to access data on my network. I have a Windows 2003 server, with hopefully enough security to keep casual hackers away, but I don't know about the intranet side. I've also got various XP/Vista machines connected, some via AD logons, and some from local workgroups. The wifi cnnnection uses WPA/PSK on a Netgear DG824N router.
Other than removing Everyone permissions from my network shares, what would I need to do to lock down access from the inside? Presumably this is a fairly common requirement from hotels/coffee shops with open wifi access.
