Internet 中的 网络安全

You are offering your IP address to the entire world at this very moment.
你每时每刻都在为整个世界提供你的IP地址。

Make sure you are not offering access to your private data at the same time.
确定你没有在此时公布你的私人数据访问信息。


YOUR IP ADDRESS IS PUBLIC
你的IP地址是公共的

Accessing the Internet is a security risk.
访问互联网会承担一定的风险。

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.
当你连接到互联网时,IP地址是用于确定你的PC所在的位置的。如果你不能够很好的保护自己,那么,这个IP地址就会被外界用来访问你的计算机。

A fixed IP address is a larger security risk.
固定IP的危险性更大

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.
如果你使用modem拨号上网,那么你的IP每时每刻都是在改变的。但是,如果你有一个固定的网络连接接口(cable、ADSL、专线),那么你的IP就是固定的。

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.
如果你的IP地址固定,那么会给网络黑客可乘之机,他们会通过专门的入口进入你的计算机,并且在你的计算机上保存信息或共享你未经保护的私人数据。


Your Network Shares
你的网络共享

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.
私人电脑通常被连接到一个共享网络中。大型公司的私人电脑被连接在大型的互联网络中;小型公司的私人电脑被连接到小型的内部局域网中;家用电脑通常是家庭成员之间的网络共享。

Most often networks are used to share resources like printers, files and disk storage.
大多数情况下,网络是用于共享打印机、文件以及硬盘存储器资源的。

When you are connected to the Internet, your shared resources can be accessed by the rest of the world.
当你连接到互联网时,你的共享信息就会被网络中其它的团体所访问。


A Common Windows Security Problem
常见的Windows安全问题

Unfortunately, many Microsoft Windows users are unaware of a common security leak in their network settings.
不幸的是,很多微软视窗系统用户对网络设置中的安全性漏洞毫不重视。

This is a common setup for network computers in Microsoft Windows:
微软的视窗系统通常会安装下面的网络组件

  • Client for Microsoft Networks
    微软网络客户端
  • File and Printer Sharing for Microsoft Networks
    文件及打印机网络共享
  • NetBEUI Protocol
    NetBEUI 协议
  • Internet Protocol TCP/IP
    网络TCP/IP协议

If your setup allows NetBIOS over TCP/IP, you have a security problem:
如果你允许在TCP / IP上安装NetBIOS,那么你将会面临下面的安全性问题:

  • Your files can be shared all over the Internet
    你的文件可以在网络中共享
  • Your login-name, computer-name, and workgroup-name are visible to others.
    你的登录名,计算机名,工作组名都可以被别人看到

If your setup allows File and Printer Sharing over TCP/IP, you also have a problem:
如果你在安装时,允许文件和打印机通过TCP / IP共享,那么,你将会面临下面的安全性问题:

  • Your files can be shared all over the Internet
    你的文件可以通过互联网共享

Computers that are not connected to any network can also have dangerous network settings because the network settings were changed when Internet was installed.
未被连入互联网的计算机也会面临网络设置上面的漏洞,因为当安装互联网时,网络设置将会被改变。
