The general steps that are involved in conducting a computer forensics investigation were also reviewed in some detail. The reasons for this include: standard-setting bodies being tied to particular legislations; standards being aimed either at law enforcement or commercial forensics but not at both; the authors of such standards not being accepted by their peers; or high joining fees for professional bodies dissuading practitioners from participating.
In other words, it takes a much deeper level of investigation by the computer forensics expert to unearth them. If these are large enough in scale and magnitude, it could even be considered as an act of Cyber terrorism, in which a significant impact can be felt in both regarding cost and human emotion.
The examiner may also wish to avoid a situation whereby turning a device off may render valuable evidence to be permanently lost. In such cases anyone may present themselves as a computer forensic expert, which may result in computer forensic examinations of questionable quality and a negative view of the profession as a whole.
Conclusions In summary, the field of computer forensics is a very broad one, and the specifics which go into it can only be defined by the circumstances in which it is techniques are being used in.
Essentially, any kind of organization that has a computer system may have a need for a digital forensics specialist.
Write blocker: a hardware device or software application which prevents any data from being modified or added to the storage medium being examined. The examiner would work from this copy, leaving the original demonstrably unchanged.
We focus primarily on what it is about, the importance of it, and the general steps that are involved in conducting a computer forensics case. In order to deal with this situation, the examiner should be prepared and able to test and experiment with the behaviour of new technologies.
However, the evidence produced would still usually be considered admissible if the examiner was able to show why such actions were considered necessary, that they recorded those actions and that they are to explain to a court the consequences of those actions.
For instance, there is often the thinking that simply fortifying the lines of defense with firewalls, routers, etc. Computer forensics has become its own area of scientific expertise, with accompanying coursework and certification.
