Digital Forensics: Everything You Need to Know
Digital forensics, also known as computer forensics or cyber forensics, is a subfield of digital science that employs investigation and analysis techniques to collect and preserve evidence from a computing device. This is done in a way that is appropriate for presenting evidence in a court of law
Fremont, CA: Forensic teams analyze and preserve digital evidence to aid in investigating technological crimes. Forensic data experts will assist in determining how an attack occurred, the extent of the damage, and, in some cases, who the perpetrator was. Digital forensics not only enables cyber security organizations to develop technologies that prevent hackers from accessing devices, websites, and networks, but it can also point businesses in the direction of determining precisely what data has been compromised. To provide closure on a cyberattack, digital forensics experts can explore networks and probe security event logs, network traffic, and access credentials.
What is the procedure for conducting a Digital Forensics Investigation? The Digital Forensics Process is divided into five stages:
Identification: This stage defines the scope of an investigation and specifies the goals and objectives that must be met. The inquiry will be guided by identifying the evidence that needs to be collected and the devices used.
Preservation: Steps are taken to ensure that as much digital evidence as possible is saved on the affected network.
Typically, preservation is done in the form of an image backup file. In addition, we must use imaging software that employs "write blockers" to ensure that the forensic examiner leaves no other digital footprints.
Analysis: Throughout the investigation, data and digital artifacts are collected, analyzed, and pieced together to determine what happened during the cyber attack. Forensic investigators delve into the incident to compile a timeline of events.
Documentation: All evidence about the cybercrime is gathered and recorded at this stage. The documentation only includes the essential information required to reach an accurate conclusion. The findings will be professionally prepared for presentation in a court of law.
Presentation : The most crucial step in an investigation is the presentation. Forensic investigators will explain what happened during the attack and present their findings so that everyone can understand. This is significant because the findings may be used for internal business investigations following the cyber attack.
