What Is Computer Forensics?
The field, which has its roots in the personal computing revolution of the late 1970s and early 1980s, developed rather haphazardly in the 1990s, and national strategies did not emerge until the early 21st century. This can provide revealing insight into the company’s digital vulnerabilities, both in terms of external sources and individuals digital forensics within the company who would not otherwise have access to the system. The investigation is primarily concerned with determining whether anyone within the company has violated company policies regarding the use of computer hardware or software. It is therefore essential that the investigator has a thorough knowledge of all operating systems.
Once they’re done, they turn the digital evidence over to police to help solve a crime or present it in court to convict a criminal. The technical aspect of an investigation is divided into several subsections related to the type of digital devices involved: Computer Forensics, Network Forensics, Data Forensics, and Mobile Device Forensics. The typical forensic process includes seizure, forensic imaging and analysis of digital media, and preparation of a report on the evidence collected. The growing importance of digital forensics has led to an increased need for computer forensics professionals. Because the role requires a specific set of skills that can be acquired through formal training and practice, EC-Council offers the Computer Hacking and Forensic Investigator program for those who want to become cyber professionals.
For example, they can trace a hack back to its source, uncover valuable evidence that sheds light on the perpetrator, and work with law enforcement to determine the crimes committed. These individuals are invaluable to a digital investigation that requires deeper insight into an organization’s information technology. Digital forensics and cybersecurity are interrelated in many ways and provide information to each other.
An important point to remember is that a digital forensic investigation will do little to prevent an attack. This does not mean that the information gathered during the investigation cannot be used by the organization to prevent attacks in the future. It can help identify vulnerabilities in the current security system that can be fixed or replaced. Digital forensics can be used to determine if suspicious activity is still taking place and alert when action needs to be taken to mitigate these potential cyber threats.
When outside forces gain access to a company’s data, it can have serious consequences from both a legal and business perspective. The most obvious factor is the theft of sensitive data such as credit card numbers, names, and phone numbers – information that allows for personal identification. The definition of digital forensics is the process of discovering and interpreting electronic data for use in court, writes Shahrzad Zargari, senior lecturer and director of the Cybersecurity with Forensics course.
This means that digital forensics experts must have deep, in-depth knowledge of as many of these systems as possible. Digital forensics is the collection, analysis, and preservation of data on electronic media, the information from which can be used as evidence in court. The practice of digital forensics can be, and often is, a profession in its own right. Although the enterprise digital forensics scientist is not a law enforcement officer, it is advisable to follow the same procedures as law enforcement when conducting digital forensics. Digital forensics is a branch of forensic science that deals with the recovery, examination, testing, and analysis of material found on digital devices, often related to mobile devices and computer crime. The term “computer forensics” was originally used as a synonym for “computer forensics” but has expanded to include the examination of any device capable of storing digital data.
In 2002, the Scientific Working Group on Digital Evidence produced a document entitled Best practices for Computer Forensics, which was followed by the publication of an ISO standard in 2005. In 2004, under European leadership, an international treaty, the Convention on Computer Crime, came into force to harmonize national computer crime laws, investigative techniques, and international cooperation. In criminal cases, it is about alleged violations of statutorily defined laws that are enforced by the police and prosecuted by the state, such as murder, robbery, and assault.
Since 2000, various bodies and agencies have issued guidelines for digital forensics to address the need for standardization. Standardization became increasingly important as law enforcement agencies moved from centralized units to regional or even local units in an effort to keep up with demand. One of the first practical examples of digital forensics was Cliff Stoll’s 1986 prosecution of Markus Hess, known for hacking into military and industrial computer networks in the United States, Europe, and East Asia. Stoll was not an expert in computer forensics, but he used computer and network forensics techniques to identify Hess.
