Post subject: wifi file sharing security Archived from groups: microsoft>public>windowsxp>security_admin (more info?)
Hi friends,
hope you are in the best of your healths.
Here it goes- I have a desktop and a laptop sharing a common internet.
The desktop is "wired" to router and laptop is connected via "wifi" to
same router.
I also share files and data between the 2 computers over LAN (not
internet). And I have allowed root sharing of the drives in both
computer.
What more can I do to secure my files and data while sharing between
the 2 systems and also from the internet??????
Its working fine. The problem is, the people next door are smart. So I
want adequate security measures to prevent misuse of my internet
connection and access to my files and data on both computer to
outsiders.
Measures already take:
1) I have enabled WPA2 only wireless security to router, given a
strong password
2) changed the default username and password of the router, to a very
strong one.

Also good
The three most basic wireless security precautions, none of which
you've mentioned:
1) Disable SSID broadcasting. This makes it harder for outsiders to
detect your network.
2) In addition to changing the wireless router's default admin username
and password, change all of the default IP addresses, both the default
DHCP server address and the DHCP range used.
3) Enable MAC filtering, so only computers that *you* specify by MAC
Address can connect to the router.

Bruce, I only left the above part of your reply because it's important
to address the idea that somehow a HOME computer doesn't warrant the
protection that an office computer would.
In many cases, in every neighborhood, you will find people running home
businesses, doing their finances, keeping identity information on their
computers. While a BUSINESS makes a very large target, a home network
makes a very nice target because they don't EXPECT to be hit or
attacked, they are just a home network, the idea is flawed.
As for what my neighbors have, well, when I was a teen, many decades
ago, people use to thing the same thing - they are only kids, or it's
only a modem....
Why should we, as professionals, not advise people of ALL of the
security issues related to securing their machines?

You can't keep Computer 3 from accessing the shares, but you can set
permissions on *users* of other computers (including Computer 3) from
accessing files on the computers with shared files.
Under XP, this can be done by disabling Simple File Sharing and setting
up permissions for your shares. This means that the two computers that
you don't want the user on the 3rd to access must be running XP Pro.
Given that, simply follow Microsoft's instructions:
"How to configure file sharing in Windows XP"
<http://support.microsoft.com/kb/304040>
The following article tells you how to set permissions on shared
folders to only allow those that you choose to have access. Skip down
to the section "Setting Permissions on a Shared Folder":
"How to disable simple file sharing and how to set permissions on a
shared folder in Windows XP"
<http://support.microsoft.com/kb/307874>
