Are there sequential dependencies between the various use cases 有不同用例之間的順序依賴嗎?
In the sequential dependency , business units operate in series and thus output from one unit becomes input to another 集中依賴是最基本的依賴形式,在這種模式中只有內部單位可以共享其公共資源,其它單位則不可以
Further , some knowledge of information theory are introduced to describe the regularity of process system calls such as the sequential dependency relationship between neighboring system calls . the use of information theory provides theoretic proof for creating more effective detecting models . in the end , applying for the maximum entropy method in information theory , a maximum entropy model of intrusion detection is presented 同時,為了提高入侵檢測的準確性,又在原有的馬爾可夫鏈模型的基礎上,引進信息理論中的信息熵,條件熵等概念來更好地刻畫進程系統調用序列的時序依賴關系,從而為建立更好的檢測模型提供信息理論依據。
