界: Time and State

分散式運算與時間和狀態相關。也就是說,為了使多個元件進行通訊,必須共用狀態,並且這一切都需要時間。

大多數的程式設計師將他們的工作擬人化。他們想採用一種控制執行緒來執行整個程式,就像他們必須自己完成這項工作一樣。但是,現代的電腦可以非常快速地切換工作,並且在多核心多 CPU 或分散式系統中,兩個事件可能恰好同時發生。瑕疵急於填補程式設計師在程式執行模型與實際情況之間的差距。這些瑕疵與執行緒、處理序、時間和資訊之間的意外互動有關。這些互動透過共用狀態發生:信號、變數、檔案系統,以及基本上任何可以儲存資訊的項目。

J2EE Bad Practices: Insufficient Session Expiration

Abstract
該方法設定永遠不會過期的階段作業。
Explanation
開啟階段作業時間愈久,攻擊者威脅使用者帳戶的機率就愈大。階段作業仍為作用中時,攻擊者可能會暴力破解使用者密碼、破解使用者的無線加密金鑰,或是從開啟的瀏覽器控制階段作業。如果足夠大量的階段作業正在執行,較長的階段作業逾時時間也會導致無法釋放記憶體,最後造成阻斷服務。

範例 1:以下範例中的程式碼為未活動時間間隔上限設定了負值,導致階段作業無限期地處於作用中狀態。

...
HttpSession sesssion = request.getSession(true);
sesssion.setMaxInactiveInterval(-1);
