Part II – Scenario

You are the digital forensic examiner at a pre-trial session with the judge and opposing counsel. You have been asked to explain the various methods that data is stored and erased in the Windows environment. Your discussion should include concepts such as slack space, unallocated space, the sequence of events that take place when a file is deleted, and any other points that you deem important. Keep in mind that you must prepare your discussion in terms that non-technical people can understand.
Written reports of no more than five pages are to be prepared in a professional manner using the APA style for your cover page and references. Format and neatness matter, as do spelling and grammar. Use one-inch margins, 12-point fonts, and double-spacing. Put page numbers on all pages but the first. Up to 30% may be deducted for work that does not meet professional standards. Some additional allowance may be made for those students for whom English is not a native language. No allowance will be made for papers that were not spell-checked. If you have trouble with the mechanics of writing, you are encouraged to get some assistance at the Academic Support Center in the Library (x6042). Also, don’t forget that there are excellent resources available through the databases at the College library (see the Reference librarian for assistance). Submit your work via Blackboard.
