Security for shared folders on a wireless network (under Windows)

post #1 of 14
Thread Starter 
Is there a way to secure shared folders under WinowsXP? While my wireless network is ubersecure (I think), anyone that I allow to use it also has acces to my shared folders and drives. So is there a way to put passwords on the folders, or better yet, to be able to share internet connection between wireless clients but allow only certain computers to share folders? I hope I made myself clear.

Found this nifty little HowTo on the web. Semms to do what I want (hide shared folders on a network). Now to see if it works properly with my Linux boxes.

If you have a WEP key on the network, no one can just see ur folders unless they have the key... Ur pretty safe... besides that u should be fine.

I use WPA, and once someone logs in to the network they have acces to pretty much everything. I found out the hard way when one of my brother's silly little friends decided to be a smartass and delete on of the shared folders (on my brother's PC) after I decided to be a nice guy and let him use our wireless network with his laptop. Nearly killed the kid out of being plain pissed off.
This will come in handy at the clinic now that I have a wireless network set up. I'm sure my stepmom will allow some of her favorite clients to use the internet while they wait, and that is what has me paranoid since she insists on being able to access the up-to-date patient logs from any of the computers in the clinic.

Here is something I found a while ago to put a password for accessing your shared folders within a network. I've lost the link to source it though.

Protect Shared Folders

Password-protecting a shared folder on a network was simple in Windows 98. How do I protect my shared folders in Windows XP?

J. Bankston, White Oak, Texas

This chore, which was easy in earlier Windows versions, is difficult and poorly documented in XP Professional and theoretically impossible in XP Home. But there's a workaround: When someone accesses your computer over a local network, XP provides access through the Guest account, even if that account is turned off. So if you password-protect the Guest account, you effectively password-protect network access to your PC.

On your XP system (which I'll call the "host"), select Start, Run, and type net user guest password, replacing password with something less obvious (see the advice in the October 2003 Internet Tips column on how to create hard-to-guess passwords). Press Enter and reboot your system.

From now on, visitors trying to log on to the host from another PC will run into a dialog box asking for the password. Without it, they can't log on. There are a couple of caveats, however.

First, visitors must first access your PC through Windows (rather than through an application), which opens a password dialog box automatically. They won't be able to access the folder on the host through another program until they've done so with Windows Explorer, the desktop, or another Windows resource.

Second, the host's Guest account must be turned off--that's the default setting. If it's on, select Start, Control Panel, User Accounts, Guest, Turn off the guest account.

This messed up my Linux shares. I can still access my Linux folders from my XP box, and I can see the network under Linux, but I can't access any shared folders from Windows. Need to figure this out.

linux will show up hidden shares on a windows machine.

if you want to secure your folders I would suggest you set your permissions for network users. (provided you're using pro.....cannot do in XP home)

when you share a folder set the permissions for everyone as full control....then in my computer select:

Tools -> Folder Options -> View -> scroll to the bottom and turn off "Simple File Share"

Now browse to the folder and right click....then select "Properties" and select the "Security" tab.

here you can specify access permissions for users.....whenever someone tries to access a network share, they will need to provide a valid username and password.....you can also give specific access permissions eg. read only or read/write but cannot delete etc.

This should secure the folder for Linux connections also.

I'm using Home. Seems like MS decided that home users do not need that much security features. It's the shared folders from Windows that I can't access from my Linux box. Following the guide I linked too, I rename all my XP shares with a $ at the end, which hides them from others. When I do that I can't see the folders under Linux, despite being able to access the network itself.

hmm......through linux you should be able to see all shares including your hidden.
