辨別遠(yuǎn)程主機(jī)的操作系統(tǒng),這是一個(gè)很重要的領(lǐng)域。了解主機(jī)操作系統(tǒng)可以分析和獲取一些信息,例如記憶管理,CPU的類型。這些信息對(duì)于計(jì)算機(jī)網(wǎng)絡(luò)的攻擊與防御非常重要。
主要的辨別是通過TCP/IP指紋識(shí)別來完成的。幾乎所有的操作系統(tǒng)的定制他們自己的協(xié)議棧都通過以下的RFC。這種情況導(dǎo)致一個(gè)實(shí)例,每個(gè)協(xié)議棧會(huì)有細(xì)節(jié)上的不同。這些不同的細(xì)節(jié)就是所知道的使辨別操作系統(tǒng)稱為可能的指紋識(shí)別。

Be it is that the media of Japan intend to inspire a sense of national self-improvement in its people, or that the US media further play up the “theory of China threat” as raised by some Americans, in short, recently, some foreign media have all along been preaching that China has become a “world factory”.
It seems that this kind of “preaching” is not wind coming from hollow cave-being not a groundless rumor, perhaps reliable data are enough to make us “feel complacent”:
“China-made” products have penetrated into every corner of the world, in 2001 alone, the volume of China's export commodities reached US$266 billion, of which 90 percent belonged to industrial manufactured products. At the same time, 80 percent of the world top 500 transnational enterprises have entered China, 390,000 foreign-funded enterprises have been operating in China, China has leapt to second place in the world in the absorption of foreign direct investment.
