2.7. Fortress Overview Document

A fortress overview document (FOD) is a detailed description of a specific fortress, including any information that a fortress outsider might find helpful to know, such as information about the data strongbox, the drawbridges, the high-level algorithms that the fortress implements, and the major technologies that are used inside the fortress. The FOD does not include implementation details of the fortress. It is used primarily to communicate information to people outside the fortress.
