Digital forensics (sometimes known as digital forensic science) is a branch of forensic science encompassing the recovery, investigation, examination, and analysis of material found in digital devices, often in relation to mobile devices and computer crime.}ref name="ijde-2002" />}ref name="carrier" /> The term "digital forensics" was originally used as a synonym for computer forensics but has expanded to cover investigation of all devices capable of storing digital data.}ref name="ijde-2002" /> With roots in the personal computing revolution of the late 1970s and early 1980s, the discipline evolved in a haphazard manner during the 1990s, and it was not until the early 21st century that national policies emerged.

Digital forensics investigations have a variety of applications. The most common is to support or refute a hypothesis before criminal or civil courts. Criminal cases involve the alleged breaking of laws that are defined by legislation and enforced by the police and prosecuted by the state, such as murder, theft, and assault against the person. Civil cases, on the other hand, deal with protecting the rights and property of individuals (often associated with family disputes), but may also be concerned with contractual disputes between commercial entities where a form of digital forensics referred to as electronic discovery (ediscovery) may be involved.

Forensics may also feature in the private sector, such as during internal corporate investigations or intrusion investigations (a special probe into the nature and extent of an unauthorized network intrusion).

The technical aspect of an investigation is divided into several sub-branches related to the type of digital devices involved: computer forensics, network forensics, forensic data analysis, and mobile device forensics.}ref>"The Different Branches of Digital Forensics". BlueVoyant. 2022-03-08.</ref> The typical forensic process encompasses the seizure, forensic imaging (acquisition), and analysis of digital media, followed with the production of a report of the collected evidence.

As well as identifying direct evidence of a crime, digital forensics can be used to attribute evidence to specific suspects, confirm alibis or statements, determine intent, identify sources (for example, in copyright cases), or authenticate documents.}ref name="handbook" /> Investigations are much broader in scope than other areas of forensic analysis (where the usual aim is to provide answers to a series of simpler questions), often involving complex time-lines or hypotheses.}ref name="df-basics"/>

History

Prior to the 1970s, crimes involving computers were dealt with using existing laws. The first computer crimes were recognized in the 1978 Florida Computer Crimes Act,}ref>"The Florida Computer Crimes Act, Probably the First U. S. Legislation against Computer Crimes, Becomes Law". History of Information. 1978. Archived from the original on 2010-06-12.</ref> which included legislation against the unauthorized modification or deletion of data on a computer system.}ref name="casey" /> Over the next few years, the range of computer crimes being committed increased, and laws were passed to deal with issues of copyright, privacy/harassment (e.g., cyber bullying, happy slapping, cyber stalking, and online predators), and child pornography.}ref name="exposed" />}ref name="briefhistory" /> It was not until the 1980s that federal laws began to incorporate computer offences. Canada was the first country to pass legislation in 1983.}ref name="casey" /> This was followed by the US Federal Computer Fraud and Abuse Act in 1986, Australian amendments to their crimes acts in 1989, and the British Computer Misuse Act in 1990.}ref name="casey" />}ref name="briefhistory" />

1980s–1990s: Growth of the field

The growth in computer crime during the 1980s and 1990s caused law enforcement agencies to begin establishing specialized groups, usually at the national level, to handle the technical aspects of investigations. For example, in 1984, the FBI launched a Computer Analysis and Response Team and the following year a computer crime department was set up within the British Metropolitan Police fraud squad. As well as being law enforcement professionals, many of the early members of these groups were also computer hobbyists and became responsible for the field's initial research and direction.}ref name="mohay" />}ref name="sommer" />

One of the first practical (or at least publicized) examples of digital forensics was Cliff Stoll's pursuit of hacker Markus Hess in 1986. Stoll, whose investigation made use of computer and network forensic techniques, was not a specialized examiner.}ref name="garfinkel" /> Many of the earliest forensic examinations followed the same profile.}ref name=dummies />

Throughout the 1990s, there was high demand for these new, and basic, investigative resources. The strain on central units lead to the creation of regional, and even local, level groups to help handle the load. For example, the British National Hi-Tech Crime Unit was set up in 2001 to provide a national infrastructure for computer crime, with personnel located both centrally in London and with the various regional police forces (the unit was folded into the Serious Organised Crime Agency (SOCA) in 2006).}ref name="sommer" />

During this period, the science of digital forensics grew from the ad-hoc tools and techniques developed by these hobbyist practitioners. This is in contrast to other forensics disciplines, which developed from work by the scientific community.}ref name="ijde-2002" />}ref name="palmer" /> It was not until 1992 that the term "computer forensics" was used in academic literature (although prior to this, it had been in informal use); a paper by Collier and Spaul attempted to justify this new discipline to the forensic science world.}ref name="wilding" />}ref name="collier" /> This swift development resulted in a lack of standardization and training. In his 1995 book, High-Technology Crime: Investigating Cases Involving Computers, K. Rosenblatt wrote the following:

2000s: Developing standards

Since 2000, in response to the need for standardization, various bodies and agencies have published guidelines for digital forensics. The Scientific Working Group on Digital Evidence (SWGDE) produced a 2002 paper, Best practices for Computer Forensics, this was followed, in 2005, by the publication of an ISO standard (ISO 17025, General requirements for the competence of testing and calibration laboratories).}ref name="casey" />}ref name="SWGDE" />}ref name="iso17025" /> A European-led international treaty, the Convention on Cybercrime, came into force in 2004 with the aim of reconciling national computer crime laws, investigative techniques, and international co-operation. The treaty has been signed by 43 nations (including the US, Canada, Japan, South Africa, UK, and other European nations) and ratified by 16.

The issue of training also received attention. Commercial companies (often forensic software developers) began to offer certification programs, and digital forensic analysis was included as a topic at the UK specialist investigator training facility, Centrex.}ref name="casey" />}ref name="sommer" />

In the late 1990s, mobile devices became more widely available, advancing beyond simple communication devices, and were found to be rich forms of information, even for crime not traditionally associated with digital forensics.}ref name="punja" /> Despite this, digital analysis of phones has lagged behind traditional computer media, largely due to problems over the proprietary nature of devices.}ref name="ahmed" />

Focus has also shifted onto internet crime, particularly the risk of cyber warfare and cyberterrorism. A February 2010 report by the United States Joint Forces Command concluded the following:

The field of digital forensics still faces unresolved issues. A 2009 paper, "Digital Forensic Research: The Good, the Bad and the Unaddressed" by Peterson and Shenoi, identified a bias towards Windows operating systems in digital forensics research.}ref name="goodbadugly" /> In 2010, Simson Garfinkel identified issues facing digital investigations in the future, including the increasing size of digital media, the wide availability of encryption to consumers, a growing variety of operating systems and file formats, an increasing number of individuals owning multiple devices, and legal limitations on investigators. The paper also identified continued training issues, as well as the prohibitively high cost of entering the field.}ref name="garfinkel" />

Development of forensic tools

Main article: List of digital forensics tools

During the 1980s, very few specialized digital forensic tools existed. Consequently, investigators often performed live analysis on media, examining computers from within the operating system using existing sysadmin tools to extract evidence. This practice carried the risk of modifying data on the disk, either inadvertently or otherwise, which led to claims of evidence tampering. A number of tools were created during the early 1990s to address the problem.

The need for such software was first recognized in 1989 at the Federal Law Enforcement Training Center, resulting in the creation of IMDUMP }ref>Mohay, George M. (2003). Computer and Intrusion Forensics. Artech House. ISBN 9781580536301.</ref>(by Michael White) and in 1990, SafeBack }ref>Fatah, Alim A.; Higgins, Kathleen M. (February 1999). Forensic Laboratories: Handbook for Facility Planning, Design, Construction and Moving. DIANE Publishing. ISBN 9780788176241.</ref>(developed by Sydex). Similar software was developed in other countries; DIBS (a hardware and software solution) was released commercially in the UK in 1991, and Rob McKemmish released Fixed Disk Image free to Australian law enforcement.}ref name="mohay" /> These tools allowed examiners to create an exact copy of a piece of digital media to work on, leaving the original disk intact for verification. By the end of the 1990s, as demand for digital evidence grew, more advanced commercial tools such as EnCase and FTK were developed, allowing analysts to examine copies of media without using any live forensics.}ref name="casey" /> More recently, a trend towards "live memory forensics" has grown, resulting in the availability of tools such as WindowsSCOPE.

More recently, the same progression of tool development has occurred for mobile devices; initially investigators accessed data directly on the device, but soon specialist tools such as XRY or Radio Tactics Aceso appeared.}ref name="casey" />

Forensic process

Main article: Digital forensic process

A digital forensic investigation commonly consists of 3 stages:

• acquisition or imaging of exhibits,}ref name="adams" />
• analysis, and
• reporting.}ref name="casey" />}ref name="first" />

Ideally acquisition involves capturing an image of the computer's volatile memory (RAM)}ref name="liveram" /> 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. However, the growth in size of storage media and developments such as cloud computing }ref name="adamscloud" /> have led to more use of 'live' acquisitions whereby a 'logical' copy of the data is acquired rather than a complete image of the physical storage device.}ref name="adams" /> Both acquired image (or logical copy) and original media/data are hashed (using an algorithm such as SHA-1 or MD5) and the values compared to verify the copy is accurate.}ref name="horenbeeck" />

An alternative (and patented) approach (that has been dubbed 'hybrid forensics'}ref name=":0">Richard, Adams; Graham, Mann; Valerie, Hobbs (2017). "ISEEK, a tool for high speed, concurrent, distributed forensic data acquisition". {{cite journal}}: Cite journal requires |journal= (help)</ref> or 'distributed forensics'}ref>Hoelz, Bruno W. P.; Ralha, Célia Ghedini; Geeverghese, Rajiv (2009-03-08). "Artificial intelligence applied to computer forensics". Proceedings of the 2009 ACM symposium on Applied Computing. ACM. pp. 883–888. doi:10.1145/1529282.1529471. ISBN 9781605581668. S2CID 5382101.</ref>) combines digital forensics and ediscovery processes. This approach has been embodied in a commercial tool called ISEEK that was presented together with test results at a conference in 2017.}ref name=":0"/>

During the analysis phase an investigator recovers evidence material using a number of different methodologies and tools. In 2002, an article in the International Journal of Digital Evidence referred to this step as "an in-depth systematic search of evidence related to the suspected crime."}ref name="ijde-2002" /> In 2006, forensics researcher Brian Carrier described an "intuitive procedure" in which obvious evidence is first identified and then "exhaustive searches are conducted to start filling in the holes."}ref name="df-basics"/>

The actual process of analysis can vary between investigations, but common methodologies include conducting keyword searches across the digital media (within files as well as unallocated and slack space), recovering deleted files and extraction of registry information (for example to list user accounts, or attached USB devices).

The evidence recovered is analyzed to reconstruct events or actions and to reach conclusions, work that can often be performed by less specialized staff.}ref name="ijde-2002" /> When an investigation is complete the data is presented, usually in the form of a written report, in lay persons' terms.}ref name="ijde-2002" />

Application

Digital forensics is commonly used in both criminal law and private investigation. Traditionally it has been associated with criminal law, where evidence is collected to support or oppose a hypothesis before the courts. As with other areas of forensics this is often a part of a wider investigation spanning a number of disciplines. In some cases, the collected evidence is used as a form of intelligence gathering, used for other purposes than court proceedings (for example to locate, identify or halt other crimes). As a result, intelligence gathering is sometimes held to a less strict forensic standard.

In civil litigation or corporate matters, digital forensics forms part of the electronic discovery (or eDiscovery) process. Forensic procedures are similar to those used in criminal investigations, often with different legal requirements and limitations. Outside of the courts digital forensics can form a part of internal corporate investigations.

A common example might be following unauthorized network intrusion. A specialist forensic examination, into the nature and extent of the attack, is performed as a damage limitation exercise, both to establish the extent of any intrusion and in an attempt to identify the attacker.}ref name="handbook" />}ref name="df-basics" /> Such attacks were commonly conducted over phone lines during the 1980s, but in the modern era are usually propagated over the Internet.}ref name=kruse />

The main focus of digital forensics investigations is to recover objective evidence of a criminal activity (termed actus reus in legal parlance). However, the diverse range of data held in digital devices can help with other areas of inquiry.}ref name="handbook" />

Attribution

Meta data and other logs can be used to attribute actions to an individual. For example, personal documents on a computer drive might identify its owner.

Alibis and statements

Information provided by those involved can be cross checked with digital evidence. For example, during the investigation into the Soham murders the offender's alibi was disproved when mobile phone records of the person he claimed to be with showed she was out of town at the time.

Intent

As well as finding objective evidence of a crime being committed, investigations can also be used to prove the intent (known by the legal term mens rea). For example, the Internet history of convicted killer Neil Entwistle included references to a site discussing How to kill people.

Evaluation of source

File artifacts and meta-data can be used to identify the origin of a particular piece of data; for example, older versions of Microsoft Word embedded a Global Unique Identifier into files which identified the computer it had been created on. Proving whether a file was produced on the digital device being examined or obtained from elsewhere (e.g., the Internet) can be very important.}ref name="handbook" />

Document authentication

Related to "Evaluation of source," meta data associated with digital documents can be easily modified (for example, by changing the computer clock you can affect the creation date of a file). Document authentication relates to detecting and identifying falsification of such details.

Limitations

One major limitation to a forensic investigation is the use of encryption; this disrupts initial examination where pertinent evidence might be located using keywords. Laws to compel individuals to disclose encryption keys are still relatively new and controversial.}ref name="garfinkel" /> But always more frequently there are solutions to brute force passwords or bypass encryption, such as in smartphones or PCs where by means of bootloader techniques the content of the device can be first acquired and later forced in order to find the password or encryption key.

Legal considerations

The examination of digital media is covered by national and international legislation. For civil investigations, in particular, laws may restrict the abilities of analysts to undertake examinations. Restrictions against network monitoring or reading of personal communications often exist.}ref name="mocas" /> During criminal investigation, national laws restrict how much information can be seized.}ref name="mocas" /> For example, in the United Kingdom seizure of evidence by law enforcement is governed by the PACE act.}ref name="casey" /> During its existence early in the field, the "International Organization on Computer Evidence" (IOCE) was one agency that worked to establish compatible international standards for the seizure of evidence.}ref name="kanellis" />

In the UK, the same laws covering computer crime can also affect forensic investigators. The 1990 Computer Misuse Act legislates against unauthorized access to computer material. This is a particular concern for civil investigators who have more limitations than law enforcement.

An individual's right to privacy is one area of digital forensics which is still largely undecided by courts. The US Electronic Communications Privacy Act places limitations on the ability of law enforcement or civil investigators to intercept and access evidence. The act makes a distinction between stored communication (e.g. email archives) and transmitted communication (such as VOIP). The latter, being considered more of a privacy invasion, is harder to obtain a warrant for.}ref name="casey" />}ref name="rosenblatt" /> The ECPA also affects the ability of companies to investigate the computers and communications of their employees, an aspect that is still under debate as to the extent to which a company can perform such monitoring.}ref name="casey" />

Article 5 of the European Convention on Human Rights asserts similar privacy limitations to the ECPA and limits the processing and sharing of personal data both within the EU and with external countries. The ability of UK law enforcement to conduct digital forensics investigations is legislated by the Regulation of Investigatory Powers Act.}ref name="casey" />

Digital evidence

Digital evidence can come in a number of forms

Main article: Digital evidence

When used in a court of law, digital evidence falls under the same legal guidelines as other forms of evidence, as courts do not usually require more stringent guidelines.}ref name="casey" />}ref name="legal"/> In the United States, the Federal Rules of Evidence are used to evaluate the admissibility of digital evidence. The United Kingdom PACE and Civil Evidence acts have similar guidelines and many other countries have their own laws. US federal laws restrict seizures to items with only obvious evidential value. This is acknowledged as not always being possible to establish with digital media prior to an examination.}ref name="mocas" />

Laws dealing with digital evidence are concerned with two issues:

• Integrity - it's ensuring that the act of seizing and acquiring digital media does not modify the evidence (either the original or the copy).
• Authenticity - refers to the ability to confirm the integrity of information; for example that the imaged media matches the original evidence.}ref name="mocas" />

The ease with which digital media can be modified means that documenting the chain of custody from the crime scene, through analysis and, ultimately, to the court, (a form of audit trail) is important to establish the authenticity of evidence.}ref name="casey" />

Attorneys have argued that because digital evidence can theoretically be altered it undermines the reliability of the evidence. US judges are beginning to reject this theory, in the case US v. Bonallo the court ruled that "the fact that it is possible to alter data contained in a computer is plainly insufficient to establish untrustworthiness."}ref name="casey" />}ref name="bonallo" /> In the United Kingdom, guidelines such as those issued by ACPO are followed to help document the authenticity and integrity of evidence.

Digital investigators, particularly in criminal investigations, have to ensure that conclusions are based upon factual evidence and their own expert knowledge.}ref name="casey" /> In the US, for example, Federal Rules of Evidence state that a qualified expert may testify “in the form of an opinion or otherwise” so long as:

The sub-branches of digital forensics may each have their own specific guidelines for the conduct of investigations and the handling of evidence. For example, mobile phones may be required to be placed in a Faraday shield during seizure or acquisition to prevent further radio traffic to the device. In the UK forensic examination of computers in criminal matters is subject to ACPO guidelines.}ref name="casey" /> There are also international approaches to providing guidance on how to handle electronic evidence. The "Electronic Evidence Guide" by the Council of Europe offers a framework for law enforcement and judicial authorities in countries who seek to set up or enhance their own guidelines for the identification and handling of electronic evidence.}ref name="EEG" />

Investigative tools

The admissibility of digital evidence relies on the tools used to extract it. In the US, forensic tools are subjected to the Daubert standard, where the judge is responsible for ensuring that the processes and software used were acceptable.

In a 2003, paper Brian Carrier argued that the Daubert guidelines required the code of forensic tools to be published and peer reviewed. He concluded that "open source tools may more clearly and comprehensively meet the guideline requirements than would closed-source tools."}ref name="tools-legal" />

In 2011, Josh Brunty stated that the scientific validation of the technology and software associated with performing a digital forensic examination is critical to any laboratory process. He argued that "the science of digital forensics is founded on the principles of repeatable processes and quality evidence therefore knowing how to design and properly maintain a good validation process is a key requirement for any digital forensic examiner to defend their methods in court."}ref name="tools-validation" />

Branches

Digital forensics investigation is not restricted to retrieve data merely from the computer, as laws are breached by the criminals and small digital devices (e.g. tablets, smartphones, flash drives) are now extensively used. Some of these devices have volatile memory while some have non-volatile memory. Sufficient methodologies are available to retrieve data from volatile memory, however, there is lack of detailed methodology or a framework for data retrieval from non-volatile memory sources.}ref>Jansen, Wayne (2004).

Retrieved 26 February 2006.</ref> Depending on the type of devices, media or artifacts, digital forensics investigation is branched into various types.

Computer forensics

The goal of computer forensics is to explain the current state of a digital artifact; such as a computer system, storage medium or electronic document.}ref name="cf-education">A Yasinsac; RF Erbacher; DG Marks; MM Pollitt (2003). "Computer forensics education". IEEE Security & Privacy. 1 (4): 15–23. doi:10.1109/MSECP.2003.1219052.</ref> The discipline usually covers computers, embedded systems (digital devices with rudimentary computing power and onboard memory) and static memory (such as USB pen drives).

Computer forensics can deal with a broad range of information; from logs (such as internet history) through to the actual files on the drive. In 2007, prosecutors used a spreadsheet recovered from the computer of Joseph Edward Duncan to show premeditation and secure the death penalty.}ref name="handbook" /> Sharon Lopatka's killer was identified in 2006 after email messages from him detailing torture and death fantasies were found on her computer.}ref name="casey" />

Mobile device forensics

Main article: Mobile device forensics

Mobile phones in a UK Evidence bag

Mobile device forensics is a sub-branch of digital forensics relating to recovery of digital evidence or data from a mobile device. It differs from Computer forensics in that a mobile device will have an inbuilt communication system (e.g. GSM) and, usually, proprietary storage mechanisms. Investigations usually focus on simple data such as call data and communications (SMS/Email) rather than in-depth recovery of deleted data.}ref name="casey" />}ref name="maarten-mob" /> SMS data from a mobile device investigation helped to exonerate Patrick Lumumba in the murder of Meredith Kercher.}ref name="handbook" />

Mobile devices are also useful for providing location information; either from inbuilt gps/location tracking or via cell site logs, which track the devices within their range. Such information was used to track down the kidnappers of Thomas Onofri in 2006.}ref name="handbook" />

Network forensics

Main article: Network forensics

Network forensics is concerned with the monitoring and analysis of computer network traffic, both local and WAN/internet, for the purposes of information gathering, evidence collection, or intrusion detection.}ref>Gary Palmer, A Road Map for Digital Forensic Research, Report from DFRWS 2001, First Digital Forensic Research Workshop, Utica, New York, 7–8 August 2001, Page(s) 27–30</ref> Traffic is usually intercepted at the packet level, and either stored for later analysis or filtered in real-time. Unlike other areas of digital forensics network data is often volatile and rarely logged, making the discipline often reactionary.

In 2000, the FBI lured computer hackers Aleksey Ivanov and Gorshkov to the United States for a fake job interview. By monitoring network traffic from the pair's computers, the FBI identified passwords allowing them to collect evidence directly from Russian-based computers.}ref name="casey" />}ref name="moscowtimes" />
