Keys to Assignment Success

Assessable Workshop: Forensic Investigation Plan

Digital forensic investigations cannot be conducted without a written permission or warrant. In this assignment, you will write a plan that you would forward to your (hypothetical) line manager to get approval so that you can proceed with the investigation, and also to make him understand the requirements of the task so that he or she can assign hardware and software resources as well as the right number of investigators to the case.

Assignment Brief

This assessable workshop is designed to get you thinking about how you may approach the case study assignment. Using the case study outline, your task is to prepare a plan (using Microsoft Word) that describes your understanding, method and intentions for undertaking the actual investigation. Remember, at this point in time, your (hypothetical) line manager has not yet approved you to commence the investigation. Hence, you are outlining all the facts to obtain formal permission to proceed with the investigation.

Length: Maximum of four A4 pages in total. You are not required to submit an ECU cover sheet.

PRO TIP: always address the assignment instructions

The keys to understanding the assignment instructions have been highlighted above.

For example (from the Assignment Brief):

“Describe your understanding, method and intentions for undertaking the actual investigation” o If you discuss investigation methods without putting them in context of the “actual investigation,” you may not get full marks.

o If you go too deep into analysing the forensically sound copy of the drive of the suspect’s computer, you will be exceeding the scope of the assignment. You will not gain marks for this effort, and you may even lose marks if assessable parts are sacrificed.

“Maximum of 4 A4 pages” o If your assignment is significantly shorter than the maximum, it may indicate that you have insufficiently covered key topics for your proposal.

o If your assignment exceeds the 4-page maximum, your may have included too much detail and may not have communicated effectively (see Marking Key)
