Q. This is a question of some debate in my organization: which way should the following document (and other similar documents) be abbreviated? Federal Information Security Management Act of 2002 (FISMA) or Federal Information Security Management Act (FISMA) of 2002?

A. If FISMA refers only to the act of 2002, and no other FISM acts were created in other years, then the first version is correct, although somewhat ambiguous. Otherwise, the second version is correct.
