Web Security

Always keep in mind that you are offering your IP address to the entire world at this very moment and make sure that you are not offering access to your private data at the same time.

YOUR IP ADDRESS IS PUBLIC

Accessing to the Internet is a security risk.

An IP address is used to identify your PC,when you are connected to the Internet, . This IP address can be used to access your computer from the outside world,if you don't protect yourself,.

A fixed IP address is a larger security risk

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 your IP address will never change if you have a fixed Internet connection (cable, ADSL, fixed line), .

If you have a fixed IP address, you give potential Internet crackers all the time they need to store and share (with other crackers) information they might find about your unprotected private data and to search for entrances to your computer.

Your Network Shares

In large companies,personal computers are connected to large corporate networks. Personal computers in private homes often share a network between family members and computers in small companies are connected to a small local network. Personal computers are connected to a shared network.

To share resources like printers, files and disk storage,networks are used

Your shared resources can be accessed by the rest of the world,when you are connected to the Internet.

A Common Windows Security Problem

Many Microsoft Windows users are unaware of a common security leak in their corresponding network settings.

In Microsoft Windows,this is a common setup for network computers :

At first,search the client for Microsoft Networks
Then File and Printer Sharing for Microsoft Networks
Then use the NetBEUI Protocol
After that use Internet Protocol TCP/IP to connect to the internet.

You have a security problem,if your setup allows NetBIOS over TCP/IP:

All over the Internet,your files can be shared
Your logon-name, workgroup-name, and computer-name are visible to others.

If your setup allows Printer and File Sharing over TCP/IP, you also have a problem:

At first,your files can be shared all over the Internet

Computers that are not connected to any network can also have dangerous network settings because when Internet was installed,the network settings were changed.

Solving the Problem

For the Windows 2000 users:

By disabling NetBIOS over TCP/IP,you can solve your security problem :

At first,open Windows Explorer
Then right-click on My Network Places
Then select: Properties
Then right-click on Local Area Network
After that select: Properties
Then select: Internet Protocol TCP/IP
Then click on Properties
Then click on Advanced
Then select the WINS tab
Then select Disable NetBIOS over TCP/IP
After that click OK

If you get the message: "This connection has an empty......", ignore the message and then click on YES to continue, and after that click OK to close the other setup windows.

After the changes,you should restart your computer.

For Windows ME,95 or 98 users:

By disabling NetBIOS over TCP/IP,you can solve your security problem :

At first,open Windows Explorer
Then right-click on My Network Places
Then select: Properties
Then right-click on Local Area Network
After that select: Properties
Then select: Internet Protocol TCP/IP
Then click on Properties
Then click on Advanced
Then select the WINS tab
Then select Disable NetBIOS over TCP/IP
After that click OK

For Microsoft Networks and File and Printer Sharing,you must also disable the TCP/IP Bindings to Client

At first,open Windows Explorer
Then right-click on My Network Places
Then select: Properties
Then select: Internet Protocol TCP/IP
Then click on Properties
Then select the Bindings tab
Then uncheck: Client for Microsoft Networks
Then uncheck: File and Printer Sharing
Then click OK

If you get a message with something like: "You must select a driver.........", ignore the message and then click on YES to continue, and after that click OK to close the other setup windows.

You must use the NetBEUI protocol instead of the TCP/IP protocol,if you still want to share your Files and Printer over the network.Your local network,always make sure you have enabled it :

At first,open Windows Explorer
Then right-click on My Network Places
Then select: Properties
Then select: NetBEUI
Then click on Properties
Then select the Bindings tab
Then check: Client for Microsoft Networks
Then check: File and Printer Sharing
After that,click OK

After the changes,you should restart your computer .
