Additionally, you can convert the color depth of the image to a different format. You do this using a derived class from BitmapImage called FormatConvertedBitmap. You specify the image using its Source property and the new color depth using the DestinationFormat property. The following is an example: <Image> <Image.Source> <FormatConvertedBitmap Source="FishTn.jpg" DestinationFormat="Gray16" /> </Image.Source> </Image> The available DestinationFormats include the following: Indexed1, Indexed2, Indexed4, and Indexed8, which provide palette-based bitmaps with fixed palettes of 2, 4, 16, and 256 colors, respectively BlackWhite, which dithers the image into two colors Gray2, Gray4, Gray8, Gray16, and Gray32, which provide 4, 16, and 256 16-bit and 32-bit grayscale images Bgr555, which specifies a 15-bit per pixel color format Bgr565, which also specifies a 16-bit per pixel color format with 6 green bits Rgb128Float, which specifies 128 bits per pixel For a full specification of the available color depths, check out the members of the System.Windows.Media.PixelFormats class.

Consider what might be the most significant types of threats to a civil liberties web site or the White House web site. Since these web sites are created by organizations that advocate a particular political stance, an attacker is probably interested in making some kind of political statement against these organizations. Therefore, the most significant threat against such sites may be defacement. Defacement is a form of online vandalism in which attackers replace legitimate pages of an organization s web site with illegitimate ones. In the years 1999 and 2001, for example, the White House web site was defaced by supposed anti-NATO activists (Dennis and Gold 1999) and Chinese hackers (Anderson 2001). In such defacement attacks, the attackers usually replace the front page of a web site with one of their own choice. Defacement is a very different type of threat than what other web sites, such as financial institutions or e-commerce vendors, might face. The attackers of these web sites may be most interested in compromising bank accounts or conducting credit card fraud. Therefore, how we design systems to be secure against attacks is dependent on the type of threats that we expect them to face. In the case of a politically oriented web site, say, www.whitehouse.gov, there may be a database where all of the content for that web site is stored. The owner of the web site may not care if an attacker gains read-only access to the information in that database however, they do not want the attacker changing the information in that database. On the other hand, a financial institution or e-commerce web site does not want the attacker to be able to even read the information in the back-end database. If this happened, the credit card or account numbers of clients might be compromised.

In general, infiltration is an attack in which an unauthorized party gains full access to the resources of a computer system (including, but not limited to, use of the CPUs, disks, and network bandwidth). In later chapters, we study how buffer overflow, command injection, and other software vulnerabilities can be used by attackers to infiltrate and own computers. In some defacement attacks, an attacker may have to infiltrate a web server to conduct the defacement. But the threat from infiltration can be quite different than that of defacement, depending on the type of web site. Consider the threat from an infiltration in which an attacker is able to write to a database running behind, say, a financial web site, but not be able to read its contents. If the attacker is able to write information to the database without reading it, the situation might not be as bad as you might think. So long as you can detect that the attacker s write took place, the situation can be mitigated. You can always restore the correct account numbers and balances from a backup database, and redo all transactions that occurred after the unauthorized writes to prevent your users from being affected. (For the purposes of this example, we assume that even if an attacker is able to write the database content, the attacker would not be able to rewrite logs. In the real world, attackers can sometimes also rewrite logs, which presents greater problems.) So, in the case of the political web site, you most importantly need to defend against an attacker who attempts to gain write capability, while in the case of a financial web site, it is most important to defend against an attacker who attempts to gain read capability.
