基於運行環境事件之程式行為萃取及其應用
為了解決javascript if in 的問題,作者李泓暐 這樣論述:
由於電腦科技逐漸在各處都可見其身影和日益複雜的電腦系統,了解那些在電腦系統中的程式行為無可避免地成為一個重要的議題。鑒於在沒有程式輸入下僅靠程式原始碼來分析程式是有困難的,又或者靠程式機器碼,但即使是一個簡單程式,其機器碼也相當複雜而難以分析,本篇論文轉而藉由觀測那些在程序(運行中的程式)所觸發的事件來分析程式行為。雖然那些事件自然地蘊含了許多關於該程式的資訊,但相對的,種類繁多的事件語意和格式仰賴於執行環境,若要有較好的偵測效率或效果,將使得觀測或分析時期的優化需要大量的專家知識。除此之外,一次大量的事件或是快速的事件生成速率(尤其是在觀測低階事件)皆會限制其線上應用。本篇論文將提出兩個程
式行為模型涵蓋了三種不同面向的程式行為,這些行為在現今環境都有非常廣泛的應用。流域模型(Watershed model)針對程式計算量和並行性,而輪廓模型(Profile model)針對程式功能性,而且這些模型的輸入能夠非常簡單地從真實系統事件中進行對應,不需要大量專家知識以及完整的事件語意。為了證明這些模型的實務價值,本篇論文實作了兩個雛型系統分別基於其中一個模型在效能分析和安全應用上,並且進行充分地評估。
