The necessity of developing a digital evidence ontology, A framework to (Im) Prove „Chain of Custody “in Digital Investigation Process, An ontological approach to study and manage digital chain of custody of digital evidence, Digital Chain of Custody : State Of The Art. Fraud investigations involving digital evidence require advanced digital forensics skills to deal with the complexities and legal issues of extracting, preserving and analyzing electronic evidence. The overview of the digital forensics comprises the life cycle of the digital forensics with different stages, i.e., the preparation, collection, analysis, and reporting. evidence. A digital forensic investigation commonly consists of 3 stages: acquisition or imaging of exhibits, analysis, and reporting. The following is an excerpt from the book Digital Forensics Processing and Procedures written by David Watson and Andrew Jones and published by Syngress. It is very difficult to maintain and prove chain of custody. 1 which is an extended version of the digital forensics progress model in block4forensics . Then investigator has to determine how we can protect the stored data from misuse and tampering that is known as chain of custody, that means investigator has to prove that nobody has alter or tampered the evidential data after it has been collected by him. Forensic science is a scientific method of gathering and examining information about the past which is then used in the court of law. Ideally acquisition involves capturing an image of the computer's volatile memory (RAM) and creating an exact sector level duplicate (or "forensic duplicate") of the media, often using a write blocking device to prevent modification of the original.

Forensic Investigation Life Cycle (FILC) using 6‘R ’ Policy for Digital Evidence Collection and Legal Prosecution The analysis of this layer includes processing the custom layout and even recovering deleted data after it has been overwritten. The latter is defined as the capability of an organisation to conduct a digital investigation by maximizing the potential use of forensic artifacts, while minimizing the cost of conducting an investigation [10] , [11] . As cybersecurity breaches continue to affect almost every industry and organization type on a virtually daily basis, the need for personnel with strong skills in handling cybersecurity incidents is as critical as ever. The process is predominantly used in computer and mobile forensic investigations and consists of three steps: acquisition, analysis and reporting. So the investigator should has knowledge of different kind of storage devices, and how the data of that storage device is taken in to own storage devices without loss and alteration of the data, which can be further use as legal evidence in the court. detail. Digital Forensics, Part 5: Analyzing the Windows Registry for Evidence. But sometimes court will not accept the same data as valid evidence because of the improper representation of the digital evidence. Digital forensics has a certain process as well: collection, examination, analysis, reporting. Since it is very difficult to store all the data related to the case in the repository, investigator has to find that; what are the important datasets that can be useful for the future use and only those data is stored in the repository. Our Digital Forensics and Incident Response (DFIR) retainer service works in concert with other offerings to ensure that IT operational resilience, continuity and recovery processes effectively support your business objectives. NIST Special Publication 800-86 Guide to Integrating Forensic Techniques into Incident Response is a valuable resource for organizations that require guidance in developing digital forensics plans.For example, it recommends that forensics be performed using the four-phase process. “Digital forensics is the process of uncovering and interpreting electronic data.
