In the current dynamic and increasingly competitive world, many organizations and major corporations around the world are finding the need to rely heavily on technology and other advanced methodologies in order to remain afloat and competitive in the market. Nonetheless, many are times that cyber bullying incidents occur, thus causing losses and other detrimental effects to the company. This thus calls for the need to Computer Forensics Investigation.
It is imperative to note that just like any other evidence, computer legal evidence provided should be reliable, authentic and permissible. Different states have precise guiding principles and practices for evidence retrieval and based on different states there is a given procedure that is acceptable with regards to the statues of the state. This evidence have been used to solve cases that are minor to cases such as murder cases.
Simply put, this is the use of scientific knowledge to actively look for information on materials, such as computers, seized from a crime scene, and to prove, using this data, that some form of crime has been committed. It may sound simple enough but the process necessary to ensure integrity of digital information retrieved in criminal investigations for such a purpose as a court case is intricate and equally rigorous. Basic principles that are standard internationally must be therefore be adhered to.
There are a number of methods used during the investigation and they are mostly applied by the law enforcement for example a criminologist. Cross drive analysis is an example of a technique used whereby the facts found on numerous hard drives is correlated and thus can be used to classify shared networks and hence implement irregularity detection. In cases where encryption of data is required the live analysis technique is used, the encryption keys are unruffled using tools to extract evidence.
When incidents of cyber-security and other computer-related issues happen to an organization, the Information Technology or IT department is usually expected to make a premier assessment and evaluation, in a bid to try and articulately identify the particular nature, effect, extent, as well as the general seriousness of the scenario or incident. Oftentimes, the staff will not have initially received any form of computerized forensic training.
The assessment of the evidence collected is carefully planned with early determination of an evidence review strategy, tools and methods. This may incorporate software to assist in analysis of massive data by use of keywords or specific types of files, decryption of data and discovery of files that may have been hidden in pictures or data images. More importantly, these experts also usually have requisite skills that help in interpreting the acquired evidence efficaciously.
It is important to note that even if an operating system shuts down the electrical charge that is stored in the recollection cells take time to dispel therefore, the span of time the data is reconstruct able is increased by a method called the cold boot attack. However, some tools that are essential in extracting files that are volatile require that the operating system be in a lab.
Once all the necessary data or evidence has been obtained a detailed report of all procedures, policies methods and tools used in the entire process must be well documented. These reports are especially vital in court cases because they are a way for any one who wishes to challenge the evidence to see a clear sequence of events that helps confirm that the evidence is authentic and credible which could ultimately directly affect the outcome of a court case.
