Questions is silence (or a lack of recorded information), an analyst may ask why is there no response or Questions or logical investigative leads based on the answers received. In contrast, DIA requires analysts to investigate or even “interrogate” digital devices.Īnalysts ask questions in the form of keyword searches and review digital artifacts to form additional Raw data extraction, however, does little to satisfy many of the offense elements necessary toĮstablish guilt. Process allows an organization to quickly process a large volume of data and may be an excellent first pictures, documents, spreadsheets, etc.) in the storage media, without furtherĪnalysis, to determine if the user opened the file or even knew the file was there. To manage the high volume of data that needs to be analyzed, some organizations haveĮmployed a raw data extraction process to digital evidence. That is equivalent to a stack of paper 1.6 trillion Generating or replicating eight zettabytes of information. Uphold our laws are just beginning to appreciate the need for analysts to conduct deeper “investigative”Īnalysis on digital devices to obtain a better understanding of issues being investigated. While technology progresses at lightning speed, the legal system and those who Technology into their products to collect, store, and transmit information about the user that they can Many products-from shoes and sports bras to lightbulbs and doorbells-are already incorporating We are still in the infancy of the digital age, but developers of Mobile devices (cell phones and tablets), GPS navigation devices, vehicle computer systems, Internet of Today, analysts examine everything “digital,” including desktop computers, laptops, Digital Investigative Analysts (analysists) no longer limit their analysis to standardĬomputer systems. TheĬybercrime Lab provides support to prosecutors through advanced digital investigative analysis, technicalĪnd investigative consultations, and research and training to support Department of Justice initiatives.ĭigital Investigative Analysis (DIA) is the evolution of what was previously referred to as “computerįorensics.” It is important for prosecutors to appreciate the three aspects of the profession that caused thisĭigital. The Cybercrime Lab is a group of highly trained digital investigative analysts located in theĬomputer Crime and Intellectual Property Section of the Criminal Division in Washington, DC. This article discusses some of these challenges and identifies techniques that prosecutors, agents, and analysts can consider to effectively respond to these challenges. In the last 15 years, significant challenges have arisen in the field formerly known as “computer forensics.” Among these challenges are the dramatic increase in the volume of digital evidence, the rise in use of effective encryption, the creation of new technologies that cause digital evidence to become increasingly evanescent (e.g., ephemeral), and an increased expectation amongst jurists that prosecutors not only prove that evidence was on the defendant’s computer, but attribute the evidence to the defendant. ![]() Challenges in Modern Digital Investigative AnalysisĬomputer Crime & Intellectual Property Section
