Because it is based on Ubuntu, its installation program is Ubiquity, Ubuntu’s graphical installer. But the version of Ubiquity in BackBox 3 is the pre-Ubuntu 12.10 version, so full disk encryption and automatic LVM configuration are not supported.
Except for the organization of applications in the menu, there is very little significant difference between a BackBox Session and an Xfce Session, at least as far as I could tell. When logged into the BackBox Session, all the security-specific applications are logically arranged under the Auditing menu category. In an Xfce Session, however, those same applications are distributed across several menu categories.
This screen shot shows what the BackBox Session desktop looks like. Notice the clean categorization of applications under the Auditing menu category.
Contrast that with this, which is a screen shot of the Xfce Session desktop. Most of the applications are under the Othermenu category, while a few are scattered across two or three other menu categories.
Aside from the security-specific applications, a default installation of BackBox 3 contains most applications for normal desktop use, aside from the absence of a complete Office suite. A default Xfce Session desktop contains more of those normal desktop applications than the BackBox Session. So this is one niche distribution that you can still use for normal desktop computing.
For managing applications, there is Ubuntu Software Center and Synaptic Package Manager. The rest of this article offers screen shots that show the security-specific applications that come with BackBox 3.
