conditional adj. 1.帶有條件的,有限制的;視…而定的。 2.【語法】條件的,假設的。 3.引起條件反射的。 n. 【語法】條件子句,條件詞。 be conditional on [upon] 在…條件下,以…為條件,取決于。 n. -ity 受限制性,有條件性,制約性;條件限制。 adv. -ly
On the other hand , a set of if - then conditional rules is induced to examine the relationships among attributes values . the non - stationary model also applies to the association analysis , which means the anomaly value of an attribute a ssumes a novel value under certain conditions depends on the last occurrence of novel value of the same attribute under same conditions 本文還采用if - then形式的規(guī)則對所考察的多個屬性進行關聯(lián)分析,并對規(guī)則運用上述動態(tài)模型,即某一條件下某屬性取得新值的異常值與相同條件下該屬性上次取得新值以來的時間長度有關。
While network - based intrusion detection systems usually detect packet headers or part of those headers , this system examines the packet payload as well as headers . not only the attributes are detected respectively , but also the relationships of attributes occurrence are detected according to a set of conditional rules , which is generated automatically by a machine learning algorithm 常見的基于網絡的入侵檢測系統(tǒng)一般只對網絡數(shù)據(jù)包的包頭或包頭中的某些內容進行考察,而本文實現(xiàn)的原型系統(tǒng)不僅考察數(shù)據(jù)包的包頭,而且還考察數(shù)據(jù)包應用負載的部分內容。
This paper includes the architecture diagram and important flowcharts of the system , discus ses in depth the generation and utilization of conditional rules , and presents the design of important modules which perform the packet - sniffing , muti - variant statistics and association detecting . some key data structures are listed , with description of important functions in the implementation 文中給出了該原型系統(tǒng)的總體結構圖和重要流程圖,較為詳細地介紹了條件規(guī)則的生成與使用,給出了數(shù)據(jù)包捕獲、多變量統(tǒng)計、關聯(lián)檢測等重要模塊的設計,列出了重要的數(shù)據(jù)結構,并對實現(xiàn)中所使用的主要函數(shù)做了說明。
