1.
As we have seen ,firewalls are notcomplete solutions to all computer secunty problems ,A firewall protects onlythe perimeter of its environment against attacks from outsiders who want toexecute code or access data on the machines in the protected environment ,keepin mind these points about firewalls.
Firewalls can protect an environment onlyif the firewalls control the entire perimeter ,That is ,firewalls areeffective only if no unmediated connections breach the perimeter ,If even one insidehost connects to an outside address ,bya modem for example ,the entie inside net is vulnerable through the modem andits host .
Firewalls do not protect data outside theperimeter ; data that have properly passed (outbound) through the firewall arejust as exposed as if there were no firewall.
Firewalls are the most visible part of aninstallation to the outside ,so they are the most attractive target for attack,For this reason ,several different layers of protection ,called defense indepth ,are better than relying on the strength of just a single firewall.

再问: OK,人工翻译
再答: 正如我们所见,防火墙并不能完全解决我们的安全问题。一个防火墙只能在边界布下一道防线来抵御那些试图盗取密码或者盗取信息的外来攻击者,记住这个关于防火墙的重点。 只有在防火墙能掌控整个边界的情况下才能起到保护的作用,也就是说,只有在没有未被调停的(无中介的)连接破坏边界的情况下才起作用。哪怕只有一个inside host(专业词汇,不太理解)连接到外部地址,比如通过调制解调器,那么整个host和内网都会变得非常脆弱易受侵袭。 防火墙不能保护在边界外的数据,那些完全通过(向防火墙外去的)防火墙的数据就跟没有防火墙一样暴露无遗。 对于外部来说,防火墙是可见度最高的装置,所以它极其容易引来攻击。因此,依靠各种不同的,叫做“纵深防御(defense-in-depth)”防御层,比起单独依靠防火墙来说要靠谱得多。 应该就差不多是这样啦
