Computer forensic

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.

However, all forms of evidence are important, especially when a Cyber-attack has occurred. As described before, the chain of custody starts to become a critical component at this stage. A Trojan is a piece of computer code disguised as something benign but which carries a hidden and malicious purpose. Once the original media has been copied, it is locked in a safe or other secure facility to maintain its pristine condition. Once again, there are many tools and techniques which can be used at this phase, but the analysis must meet the following criteria: It must be accurate; Every step must be documented and recorded; It must be unbiased and impartial; As far as possible, it must be completed within the anticipated time frames and the resources which have been allocated to accomplish the various analyses functions and tasks.

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.
