You are offering your IP address to the entire world at this very moment.
Äãÿʱÿ¿Ì¶¼ÔÚΪÕû¸öÊÀ½çÌṩÄãµÄIPµØÖ·¡£

Make sure you are not offering access to your private data at the same time.

Accessing the Internet is a security risk.
·ÃÎÊ»¥ÁªÍø»á³Ðµ£Ò»¶¨µÄ·çÏÕ¡£

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.
µ±ÄãÁ¬½Óµ½»¥ÁªÍøÊ±£¬IPµØÖ·ÊÇÓÃÓÚÈ·¶¨ÄãµÄPCËùÔÚµÄλÖõġ£Èç¹ûÄã²»Äܹ»ºÜºÃµÄ±£»¤×Ô¼º£¬ÄÇô£¬Õâ¸öIPµØÖ·¾Í»á±»Íâ½çÓÃÀ´·ÃÎÊÄãµÄ¼ÆËã»ú¡£

A fixed IP address is a larger security risk.
¹Ì¶¨IPµÄΣÏÕÐÔ¸ü´ó

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.

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.

Your Network Shares
ÄãµÄÍøÂç¹²Ïí

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.

A Common Windows Security Problem
³£¼ûµÄWindows°²È«ÎÊÌâ

Unfortunately, many Microsoft Windows users are unaware of a common security leak in their network settings.
²»ÐÒµÄÊÇ£¬ºÜ¶à΢ÈíÊÓ´°ÏµÍ³Óû§¶ÔÍøÂçÉèÖÃÖеݲȫÐÔ©¶´ºÁ²»ÖØÊÓ¡£

This is a common setup for network computers in Microsoft Windows:
΢ÈíµÄÊÓ´°ÏµÍ³Í¨³£»á°²×°ÏÂÃæµÄÍøÂç×é¼þ

  • Client for Microsoft Networks
    ΢ÈíÍøÂç¿Í»§¶Ë

  • NetBEUI Protocol

  • Internet Protocol TCP/IP

If your setup allows NetBIOS over TCP/IP, you have a security problem:

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

If you still want to share your Files and Printer over the network, you must use the NetBEUI protocol instead of the TCP/IP protocol. Make sure you have enabled it for your local network:
