Reino: Security Features

La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.

Privacy Violation: Image

C#/VB.NET/ASP.NET

Abstract

Una gestión incorrecta de la información confidencial como, por ejemplo, los informes empresariales, puede comprometer la privacidad corporativa y a menudo es ilegal.

Explanation

Las infracciones de privacidad se producen cuando se almacenan datos confidenciales con un formato no cifrado.

Ejemplo 1: en el siguiente código ASPX, se crea una instancia de un control DataVisualization que genera un gráfico de información financiera confidencial del origen de datos XML SensitiveXMLData:


        <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>

El código del Example 1 indica al control de Chart que genere una imagen JPEG del gráfico de barras y lo escriba en el directorio temporal ~/Temporary/Graph. Una vez que el control escribe la imagen en el disco, el explorador del usuario realizará la consiguiente solicitud del archivo y lo mostrará al usuario. La imagen no se escribe de forma segura en el disco. Además, el código presupone que la infraestructura subyacente protegerá el archivo frente al acceso no autorizado por parte de otro usuario.
