and 6. Each stage of the method has been shown to be justifiable earlier in this<br />

subsection by providing logs which document the effect on the original data<br />

therefore the process for the retrieval of thumbnail cache artefacts from<br />

unallocated space has understandable consequences.<br />

The process has a scientific method as it was created based on a hypothesis<br />

[Section 1.4], based on the justification provided in Section 1.2. A problem<br />

definition and objectives were described in Section 3.1; the methodology to test<br />

the hypothesis using both observation of the data and experimentation was<br />

provided in Section 3.3. Each individual section also contains a detailed<br />

description of the specific methods used.<br />

10.4 Typical Operation, Behaviour, Relationships and<br />

Maximising Corroboration<br />

“In order to determine an artefact was created during the typical operation of<br />

a machine it is necessary to determine the system behaviour which led to an<br />

artefacts current state.” [Chapter 4.3.2]<br />

“In order to establish the behaviour an artefact represents it is necessary to<br />

form relationships with other artefacts to identify potential system activity.”<br />

[Chapter 4.3.2]<br />

“A relationship between artefacts can be defined as an association between<br />

artefacts; the relationship may provide corroboration or supplementary<br />

information that enhances what is known about the system activity.”<br />

[Chapter 4.3.2]<br />
