【導讀】替建立幀系統(tǒng)獲得主機信息與系統(tǒng)配對從而分辨出主機操作系統(tǒng)的類別。了解主機操作系統(tǒng)可以分析和。獲取一些信息，例如記憶管理，CPU的類型。這些信息對于計算機網絡的攻擊與防御非。主要的辨別是通過TCP/IP指紋識別來完成的。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。這種情況導致一個實例，每個協(xié)議棧會有細節(jié)上的不同。Nmap、Queso在傳輸層里使用指紋。他們將特殊數據包發(fā)送到目標并分析返回的數。據包，在指紋庫中尋找配對的指紋，以便得到的結果。指紋庫中的信息受指定的探測信。所有可能的情況下確實是操作系統(tǒng)的概率。主要不足是它過分依賴ICMP協(xié)議議定書。SYNSCAN是在應用協(xié)議中與目標主機聯(lián)系時，使用的一些典型的指紋識別方法。紋庫對在這個領域有限制。Ring，Ttbit查明操作系統(tǒng)所使用TCP/IP的性能特點。其結果往往是不完全確定的。雖然這種方式是有效，它在少數特定操作系統(tǒng)區(qū)分。依靠部分TCP/IP協(xié)議。該程序是為了獲取信息，提取指紋和匹配的指紋庫里的記錄，以便知道類型。
【正文】 which are to acquire message, the action and status of munication, also classify the fingerprint. These work are all prepared for the next section which how to built a frame system describing the fingerprint. To insert “Tables” or “Figures”, please paste the data as stated below. All tables and figures must be given sequential numbers (1, 2, 3, etc.) and have a caption placed below the figure (“FigCaption”) or above the table(“FigTalbe”) being described, using 8pt font and please make use of the specified style “caption” from the dropdown menu of style categories Conclusion In this paper, we have presented a method for identifying OS of remote host. The method use frame technology to express the fingerprint, make up of Probe and Monitor to get message and abstract the information from the message to match the warehouse of fingerprint, identify the OS at last. Through experiment, this method can exactly identify the OS of remote hose with more secretly and less number of packets paring with nmap and xprobe. In the future, we plan to collect more fingerprint for each kind of OS, make the algorithm(規(guī)則系統(tǒng) ) to be more intelligent, in order to improve the precision(準確性 ) of identify.
