界: Security Features

軟體安全性並非安全性軟體。我們關注驗證、Access Control、保密性、加密以及權限管理之類的主題。

Privacy Violation: Image

Abstract
不當處理業務報告等敏感資訊,可能會洩漏公司隱私而且不合法。
Explanation
如果敏感資料以未加密格式保存在磁碟中,可能會發生 Privacy Volation。


範例 1: DataVisualization 控制會從 XML 資料來源 SensitiveXMLData 產生敏感財務資訊的圖形,下列 ASPX 程式碼可將其個體化:


<asp:Chart ID="Chart1" runat="server" ImageLocation="~/Temporary/Graph"
ImageType="Jpeg" DataSourceID="SensitiveXMLData" ImageStorageMode="UseImageLocation">
<series>
.
.
.
</series>
<chartareas>
<asp:ChartArea Name="ChartArea1">
</asp:ChartArea>
</chartareas>
</asp:Chart>
Example 1 中的程式碼會指示 Chart 控制產生長條圖的 JPEG 影像,並將其寫入暫存目錄 ~/Temporary/Graph。當控制寫入影像至磁碟後,使用者的瀏覽器將進行檔案的後續要求,並顯示檔案供使用者查看。影像並未安全地寫入磁碟。另外,程式碼假設基礎架構會保護檔案,不受其他未經授權的使用者存取。
