Just passing the CISSP exam is enough for the DoD, and there is no prerequisite to only take the exam. You can sign up for the CISSP exam now and take it tomorrow if you are ready. Once you have passed the exam then you can start thinking about how much more professional Information Security experience (not just IT experience) you need to acquire to meet the full requirements for CISSP certification.

The link for that doc is in multiple posts here at TechExams.net. As for your experience, you will need to be interviewed by an endorser to make the final determination. It's a total of 4 years experience across two domains, so depending on what you did for the legal investigations aide you may have it now. I would just think about passing the CISSP exam now and worry about the endorsement later.
