The transformation of the analog world into a digital world has raised new challenges and opportunities for technology lovers. – Tracking or identifying hacking activitiesĢ1st century is the century of revolution and change. – Recovering deleted files /Data Recovery Analyzing the data-This is perhaps the most important part of the investigation process which involves careful examination and analysis of the data using forensic tools. To ensure that the acquired data is an exact copy of the contents of the hard drive, the md5/sha1 of the original and copied data are checked and matched.ģ. Authenticating the data- The next process involves verifying the data seized. The step involves creating a bit by bit copy of the hard drive data.Ģ. Preserving and acquiring the data-The first and foremost step of a digital forensic investigation is to preserve and acquire the data from a computer.

The primary goal of Digital Forensics is to carry out an organized and structured investigation in order to preserve, identify, extract, document and interpret digital information that is then utilized to prevent, detect and solve cyber incidents.Ī typical forensic investigation consists of the following main steps:įigure 1: Steps involved in a Forensic Investigation Processġ. What is Digital Forensics/Cyber Forensics?Īlso known as cyber forensics, computer forensics involve the application of acquiring and analyzing digital information (as a part of structured investigation) to be used as evidence in the court of law. With the increasing demand of computer security in recent times, it has become more important than ever to understand the digital forensic technology. Increased rates of cyber crimes leading to unsolicited invasions of privacy have resulted in the emergence of a new field of computer science known as cyber forensics. As computer technology continues to evolve, the task of managing and handling private and sensitive information is becoming more and more challenging with each passing day. While on one hand, commercialization of IT (Information technology) revolutionized our modern day lifestyle, it has raised a big question mark about the confidentiality and privacy of the information shared and managed using advanced means of communication. Our number one priority is to support the DFIR community by not only providing content to solve even the most difficult problems investigators face daily, but also provide an open forum for community mentoring, development and support.The world we live in today is a technologically advanced world. These resources are aimed to provide you with the latest in research and technology available to help you streamline your investigations.
