Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

DEFFOR006 - Conduct electronic data search and analysis

What evidence can you provide to prove your understanding of each of the following citeria?

Reduce and describe data

  1. Identify electronic forensic data to be analysed.
  2. Reduce the data, identify possible artefacts and describe these in a suitable form to support the development of interpretations.
  3. Decrypt data if appropriate.
  4. Review the reduction and description processes to determine their appropriateness, and make improvements where necessary.
  5. Save data not used in the reduction and description processes for future reference.

  2. Analyse electronic storage devices for artefacts, i.e. any kind of tangible electronic byproduct produced during user or system activity that may become evidence.
  3. Apply sound reasoning to ensure consistency of interpretations based on the data.
  4. Base interpretations on the factual quantitative and qualitative data.
