Digital Forensics:What is Digital Forensics ?

Digital forensics, also known as computer forensics or cyber forensics, is the branch of forensic science that deals with the investigation, recovery, analysis, and presentation of digital evidence from electronic devices and digital media. It involves applying scientific and investigative techniques to collect, preserve, and analyze data stored on computers, smartphones, tablets, servers, and other digital devices.

The primary goals of digital forensics include:

1. Investigating Cybercrimes: Digital forensics is used to investigate various cybercrimes such as hacking, data breaches, malware attacks, online fraud, intellectual property theft, and cyber espionage.

2. Gathering Evidence: Digital forensics experts collect and preserve digital evidence in a forensically sound manner to ensure its integrity and admissibility in legal proceedings.

3. Reconstructing Events: By analyzing digital artifacts, logs, metadata, and other digital traces, investigators reconstruct events, timelines, and activities related to a cyber incident or crime.

4. Identifying Culprits: Digital forensics can help identify perpetrators, determine their methods and motives, and attribute cyber attacks or criminal activities to specific individuals or groups.

5. Supporting Legal Proceedings: Digital evidence collected through forensic analysis is often used in legal proceedings, including criminal investigations, civil litigation, regulatory compliance, and internal corporate investigations.

Digital forensics involves a range of techniques and tools, including disk imaging, file analysis, network forensics, memory analysis, malware analysis, and mobile device forensics. Forensic experts must adhere to strict protocols and guidelines to ensure the integrity and admissibility of the evidence collected. Additionally, they often collaborate with law enforcement agencies, legal professionals, cybersecurity specialists, and other stakeholders throughout the investigation process.

Digital forensics: In its strictest connotation, the application of computer science and investigative procedures involving the examination of digital evidence - following proper search authority, chain of custody, validation with mathematics, use of validated tools, repeatability, reporting, and possibly expert testimony.( csrc.nist.gov : CNSSI 4009-2015 from DoDD 5505.13E )

Digital forensic science is a branch of forensic science that focuses on the recovery and investigation of material found in digital devices related to cybercrime. The term digital forensics was first used as a synonym for computer forensics. Since then, it has expanded to cover the investigation of any devices that can store digital data.

Digital forensics is a new and rapidly evolving field of forensic study. Its techniques can be used in civil, administrative, and criminal proceedings in order to collect, validate, identify, analyze, interpret, document and present digital evidence. Digital evidence is information derived from devices in a way that allows it to be used in a legal proceeding.(July 6, 2019 by

Digital forensics is a field of forensic science. It is used to investigate cybercrimes but can also help with criminal and civil investigations. For instance, cybersecurity teams may use digital forensics to identify the cybercriminals behind a malware attack, while law enforcement agencies may use it to analyze data from the devices of a murder suspect.(IBM: 16 February 2024,Annie Badman, Amber Forrest)
