Digital Forensics is not an elephant, it is a process and not just one process, but a group of tasks and processes in investigation. Examiners now perform targeted examinations using forensic tools and databases of known files, selecting specific files and data types for review while ignoring files of irrelevant type and content. Despite the application of sophisticated tools, the forensic process still relies on the examiner's knowledge of the technical aspects of the specimen and understanding of the case and the law - Mark Pollitt.
As has been established from articles by various authors including myself, this re-branded model of computing now called cloud computing proposes benefits that can improve productivity, harness high-speed systems which can manage large data sets as well as systems implementations, and could have a net positive impact on the operational budget (scaling,elasticity) of some small and midsized enterprises.
Of course there is the possibility that a private cloud for a small enterprise may not warrant its cost, in comparision to that of harnessing the benefits of a public cloud offering.
For a larger enterprise with say multiple and/or international locations, a private cloud infrastructure can provide an added cost benefit that whilst not as cheap as a public cloud offering, would offset that cost variance in terms of the risk profile of systems being moved into a private cloud e.g. critical databases, transactional and/or processing systems as well as potential compliance concerns.
If however an enterprise chooses to utilize a public cloud offering there will be the added complications for information security, in terms of procedural and legal standpoints. This leads us to the point that, with a public cloud system; we no longer have the traditional defined security perimeter.
