<hr />
<p class="intro">You are offering your IP address to the entire world at this very
moment.</p>
<p class="intro">Make sure you are not offering access to your private data at the
same time.</p>
<hr />
<h2>YOUR IP ADDRESS IS PUBLIC</h2>
<p><b>Accessing the Internet is a security risk.</b> </p>
<p>When you are connected to the Internet, an IP address is used to identify your
PC. If you don't protect yourself, this IP address can be used to access your
computer from the outside world. </p>
<p><b>A fixed IP address is a larger security risk.</b> </p>
<p>If you're using a modem with a dial-up connection, you will get a new IP
address every time you connect to Internet, but if you have a fixed Internet
connection (cable, ADSL, fixed line), your IP address will never change. </p>
<p>If you have a fixed IP address, you give potential Internet crackers all the
time they need to search for entrances to your computer, and to store and share
(with other crackers) information they might find about your unprotected private data. </p>
<hr />
<h2>Your Network Shares</h2>
<p>Personal computers are often connected to a shared network. Personal
computers in large companies are connected to large corporate networks. Personal
computers in small companies are connected to a small local network, and
computers in private homes often share a network between family members.</p>
<p>Most often networks are used to share resources like printers, files and disk
storage.</p>
<p><b>When you are connected to the Internet, your shared resources can be
accessed by the rest of the world.</b></p>
<hr />
<h2>A Common Windows Security Problem</h2>
<p>Unfortunately, many Microsoft Windows users are unaware of a common security
leak in their network settings.</p>
<p>This is a common setup for network computers in Microsoft Windows: </p>
<ul type="square">
<li>Client for Microsoft Networks</li>
<li>File and Printer Sharing for Microsoft Networks</li>
<li>NetBEUI Protocol</li>
<li>Internet Protocol TCP/IP</li>
</ul>
<p><b>If your setup allows NetBIOS over TCP/IP, you have a security problem:</b></p>
<ul type="square">
<li>Your files can be shared all over the Internet</li>
<li>Your logon-name, computer-name, and workgroup-name are visible to others.</li>
</ul>
<p><b>If your setup allows File and Printer Sharing over TCP/IP, you also have a
problem:</b></p>
<ul type="square">
<li>Your files can be shared all over the Internet</li>
</ul>
<p>Computers that are not connected to any network can also have dangerous
network settings because the network settings were changed when Internet was
installed.</p>
<hr />
<h2>Solving the Problem </h2>
<p><b>For Windows 2000 users:</b> </p>
<p>You can solve your security problem by <b> disabling NetBIOS over TCP/IP</b>: </p>
<ul type="square">
<li>Open Windows Explorer</li>
<li>Right-click on My Network Places</li>
<li>Select: Properties</li>
<li>Right-click on Local Area Network</li>
<li>Select: Properties</li>
<li>Select: Internet Protocol TCP/IP</li>
<li>Click on Properties</li>
<li>Click on Advanced</li>
<li>Select the WINS tab</li>
<li>Select Disable NetBIOS over TCP/IP</li>
<li>Click OK</li>
</ul>
<p>If you get the message: "This connection has an empty......", ignore the message and click on YES to
continue, and click OK to close the other setup windows.</p>
<p>You should restart your computer after the changes.</p>
<p><b>For Windows 95, 98, or ME users:</b> </p>
<p>You can solve your security problem by <b> disabling NetBIOS over TCP/IP</b>: </p>
<ul type="square">
<li>Open Windows Explorer</li>
<li>Right-click on My Network Places</li>
<li>Select: Properties</li>
<li>Select: Internet Protocol TCP/IP</li>
<li>Click on Properties</li>
<li>Select the NetBIOS tab</li>
<li>Uncheck: Enable NetBIOS over TCP/IP</li>
<li>Click OK</li>
</ul>
<p>You must also <b> disable the TCP/IP Bindings</b> to Client for Microsoft Networks and File and Printer
Sharing: </p>
<ul type="square">
<li>Open Windows Explorer</li>
<li>Right-click on My Network Places</li>
<li>Select: Properties</li>
<li>Select: Internet Protocol TCP/IP</li>
<li>Click on Properties</li>
<li>Select the Bindings tab</li>
<li>Uncheck: Client for Microsoft Networks</li>
