Web Security

At this moment, you have provided your IP address to the entire world.

Make sure you have not provided access permissions to private data at the same time.

Your IP address is public

Accessing the Internet involves risks in terms of security.

After you connect to the Internet, the IP address is used to identify your PC. If you do not take precautions, the outside world may use this IP address (illegally) to access your computer.

Using a fixed IP address involves greater risks.

If you are using a dial-up connection modem, then each time you connect to the Internet, you will get a new IP address, but if you have a fixed IP address (cable,专线, etc.), your IP address will not change.

If you are using a fixed IP address, then you have given those hackers the possibility to attack your computer at any time.

Your network sharing

Personal computers often connect to a shared network. Personal computers in large enterprises connect to large corporate networks. Personal computers in small companies connect to small local networks, and computers in private households also often share the network with family members.

The network is often used to share printers, files, and disk storage.

When you connect to the Internet, your shared resources may be accessed by the outside world.

Common Windows Security Issues

Unfortunately, many Microsoft Windows users are not aware of the common security vulnerabilities in their network settings.

This is a list of common network component installations in Microsoft Windows:

  • Microsoft Network Client
  • Microsoft's File and Printer Network Sharing
  • Internet Protocol (TCP/IP)

If your settings allow the use of NetBIOS over TCP/IP, then you will face a security issue:

  • Files will be shared across the entire Internet
  • Your login name, computer name, and workgroup name are visible to others

If your settings allow file and printer sharing over TCP/IP, you will also face security issues:

  • Files will be shared across the entire Internet

Computers not connected to any network may also have dangerous network settings, which is because once the Internet is installed, the network settings will change.

Troubleshooting

Please disable the NetBIOS protocol and file printer sharing in the network connection properties, and the specific operation method may vary slightly depending on different versions of Windows.

If you still need to share printers and files on the network, you can choose to use the NetBEUI protocol instead of the TCP/IP protocol.
