In the identification phase, cybercrime investigators use many traditional investigative techniques (see: UNODC, Policing: Crime Investigation for a detailed analysis of these techniques), especially with respect to information and evidence gathering. For example, victims, witnesses, and suspects of a cybercrime are interviewed to gather information and evidence of the cybercrime under investigation (for guidance on interviewing suspects and adult and children witnesses and victims, see: UNODC, Anti-Human Trafficking Manual for Criminal Justice Practitioners, Module 9; UNODC, Toolkit to Combat Trafficking in Persons; UN Economic and Social Council (ECOSOC) Resolution 2005/20 Guidelines on Justice in Matters involving Child Victims and Witnesses of Crime; UNODC, Justice in Matters involving Child Victims and Witnesses of Crime; and Boyle and Vullierme, Council of Europe, A brief introduction to investigative interviewing: A practitioner's guide).
Before digital evidence collection begins, the investigator must define the types of evidence sought. Digital evidence can be found on digital devices, such as computers, external hard drives, flash drives, routers, smartphones, tablets, cameras, smart televisions, Internet-enabled home appliances (e.g., refrigerators and washing machines), and gaming consoles (to name a few), as well as public resources (e.g., social media platforms, websites, and discussion forums) and private resources (e.g. Internet service providers logs of user activity; communication service providers business records; and cloud storage providers records of user activity and content). Many applications, websites, and digital devices utilize cloud storage services. Users' data can thus be stored wholly or in fragments by many different providers in servers in multiple locations (UNODC, 2013; Quick, Martini, and Choo, 2014). Because of this, retrieving data from these providers is challenging (for more information, see Cybercrime Module 7 on International Cooperation against Cybercrime). The evidence sought will depend on the cybercrime under investigation. If the cybercrime under investigation is identity-related fraud, then digital devices that are seized will be searched for evidence of this crime (e.g., evidence of a fraudulent transactions or fraudulent transactions).

The actual collection of the evidence involves the preservation of volatile evidence and the powering down of digital devices. The state of operation of the digital devices encountered will dictate the collection procedures. For instance, if a computer is encountered, if the device is on, volatile evidence (e.g., temporary files, register, cache, and network status and connections, to name a few) is preserved before powering down the device and collecting it (Casey, 2011; Sammons, 2012; Maras, 2014; Nelson, Phillips, and Steuart, 2015). If the device is off, then it remains off and is collected (US National Institute of Justice; 2004b; US National Institute of Justice, 2008). There are circumstances where digital devices will not and cannot be collected (e.g., due to size and/or complexity of the systems and/or their hardware and software configurations, because these systems provide critical services) (see Cybercrime Module 4 on Introduction to Digital Forensics). In these situations, volatile and non-volatile data are collected through special procedures that require live acquisition ( SWGDE Capture of Live Systems , 2014). The type of digital device encountered during an investigation will also dictate the manner in which digital evidence is collected (see, for example, SWGDE Best Practices for Mobile Device Evidence Preservation and Acquisition, 2018; SWGDE Best Practices for the Acquisition of Data from Novel Digital Devices; US National Institute of Justice, 2007a).
Digital Forensics FrameworkDigital Forensics Framework (DFF) is an open-source computer forensics platform built upon a dedicated Application Programming Interface (API). Equipped with a graphical user interface for simple use and automation, DFF guides a user through the critical steps of a digital investigation and can be used by both professionals and amateurs alike.
Software enables us to accomplish many different tasks with computers. Unfortunately, in order to get our work done quickly and conveniently, some people make and use unauthorized software copies. The purpose of this guideline is to provide a brief outline of what you legally can and cannot do with software. Hopefully it will help you better understand the implications and restrictions of the U.S. Copyright Law.
As people and organizations rely more on technology, computer programmers can find work across industries. Use our guide to explore this dynamic profession, including key skills, job outlook, and career paths for computer programmers.
The CHFI course covers a wide range of topics and tools (click the exam Blueprint button on the certification webpage). Topics include an overview of digital forensics, in-depth coverage of the computer forensics investigation process, working with digital evidence, anti-forensics, database and cloud forensics, investigating network traffic, mobile and email forensics, and ethics, policies and regulations. Courseware is available, as well as instructor-led classroom training.
Both the GCFE and GCFA focus on computer forensics in the context of investigation and incident response, and thus also focus on the skills and knowledge needed to collect and analyze data from Windows and/or Linux computer systems during such activities. Candidates must possess the necessary skills, knowledge, and ability to conduct formal incident investigations and advanced incident handling, including dealing with internal and external data breaches, intrusions, and cyberthreats; collecting and preserving evidence; understanding anti-forensic techniques; and building and documenting advanced digital forensic cases. 2ff7e9595c
