专家:我们如何将掌握网络安全

2016-01-22 11:51:46   新华网

陈虎点兵:我的网络谁做主?

今天,网络已经渗入到了我们生活的每一个角落。很难想象没有网络我们该如何生活、如何工作,甚至国家和军队的管理、运行都离不开网络。由此,网络安全已经成为了公众视线的焦点。

我们关注网络安全,也了解许多确保网络安全的措施。我们有越来越复杂的密码、保密设备,甚至在涉及到国计民生、国家安全等重要领域的软件、操作系统等都拥有自主知识产权,力求通过国产化的方式保证关键性网络的安全运行。

但是,这些措施能够保证我们真正实现“我的网络我做主吗”?究竟怎样才能真正实现网络安全,做到“我的网络我做主”?

互联网并不是真正的“互联”网。所谓“互联”,应该是以平等的身份相互连接形成的网络结构,但实际上,我们今天运用的因特网并不是一个“互联”的关系,而是一个“接入”的关系。打个比方,今天的互联网更像一棵树、一个放射性的结构。这棵树的树根根植在美国的国土上,根植在美国人的手中,其它无论任何国家的网络都是这棵树上的一根树枝,甚至是一片树叶。

比如,我们要通过互联网从家里发一封电子邮件到办公地点,即使这两个地点相距只有几公里,但是电子邮件并不是直接从家里传送到办公地点,而是要兜一个大圈子。所有电子邮件都首先要进行一番“国际旅游”,走到美国,走到根服务器,然后根据根服务器的一系列推算指定接收路径。也就是说,所有互联网上信息的流动全部都要先经过美国。

由此可见,如今的网络确实不适合叫做“互联”网。在这座网络大厦中美国拥有全部产权,其它的国家不过是这座大厦中的“租客”。或许有人说,这种“租赁使用”的关系只要有足够的安全保障并没有太大问题,但实际上我们所有的信息在经过美国的过程中都有可能被盗取、被监视。从某种意义上来说,无论是个人、企业、政府或军队,只要接入因特网,都是在美国的监视下运行。

“棱镜门事件”已经向世人展现出美国监视世界的手段和事实,我们无法保证这种监视会不会变成监控。

按照现在域名的分化,不同地区的域名有不同的后缀,作为大厦的房主、产权拥有者,完全可以根据域名来判断信息来自哪里、要到哪里。如果有需要,它可以轻易的把某一个“房间”断水、断电,让其失去和外界的一切联系。伊拉克战争期间就曾发生过这样的事,战争发起时,伊拉克突然从互联网上全部消失了,这实际上向所有人敲响了警钟。

我们今天的网络自己并不能作主,我们所有的网络运行都依附在被我们误称为互联网的“美国网”上,作为真正的产权拥有者,它可以根据需要来随时处置租客们的一切权利和行为。今天的网络安全问题已经不再是加密、技术措施、技术手段所能解决的问题。如何将网络安全掌握在自己的手中,是我们每个人都在面对的问题。(陈虎)
