Computer forensics investigation and analysis represent a method for collecting and preserving evidence from a specific computing device in a manner appropriate for court presentation. The objective of computer forensics investigation is to conduct a systematic inquiry, ensuring a documented chain of evidence, with the aim of discerning precisely the events that transpired on a computing device and identifying those accountable for them.
Computer forensics plays a critical role in upholding the credibility of digital evidence presented in legal proceedings. With the increasing ubiquity of computers and data-collecting devices in various aspects of life, the significance of digital evidence and the forensic processes involved in its collection, preservation, and investigation has heightened, particularly in the resolution of crimes and legal matters.
The initiation of a computer forensics investigation involves gathering information in a manner that preserves its integrity. Subsequently, investigators analyze the data or system to ascertain whether any alterations occurred, the nature of these changes, and the identity of the individual responsible for them. Notably, computer forensics is not solely confined to criminal investigations; it is also employed in data recovery scenarios. In instances such as a crashed server, failed drive, or reformatted operating system (OS), the forensic process is utilized to retrieve data when a system unexpectedly ceases to function
There are various types of computer forensic examinations. Each deal with a specific aspect of information technology. Some of the main types include the following:
