Introduction to website construction and web security

Your IP address is public

Access to the Internet involves security risks.

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

Fixed IP addresses take more risks.

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

If you are using a fixed IP address, you give hackers the possibility to attack computers at any time.

Your network share

Personal computers are often connected to a shared network. Personal computers in large enterprises will be connected to large group networks. Personal computers in small companies will be connected to small local networks, and computers in private homes will often share networks with family members.

Networks are 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 problems

Unfortunately, many Microsoft Windows users are unaware of the common security vulnerabilities in their network settings.

This is the installation list of common network components in Microsoft Windows:

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

If your settings allow NetBIOS over TCP/IP, you will face a security problem:

• Files will be shared across the 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 problems:

• Files will be shared across the Internet

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

solve the problem

Please disable the NetBIOS protocol and file printer sharing in the network connection properties. The specific operation method will vary slightly depending on the Windows version.

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