What is Digital Forensics & Types of Digital Forensics

What is Digital Forensics?

Digital Forensics is defined as the process of preservation, identification, extraction, and documentation of computer evidence which can be used by the court of law. It is a science of finding evidence from digital media like a computer, mobile phone, server, or network. It provides the forensic team with the best techniques and tools to solve complicated digital-related cases.Digital Forensics helps the forensic team to analyzes, inspect, identifies, and preserve the digital evidence residing on various types of electronic devices.

Objectives of Computer Forensics.

• It helps to recover, analyze, and preserve computer and related materials in such a manner that it helps the investigation agency to present them as evidence in a court of law.
• It helps to postulate the motive behind the crime and identity of the main culprit.
• Designing procedures at a suspected crime scene which helps you to ensure that the digital evidence obtained is not corrupted.
• Data acquisition and duplication: Recovering deleted files and deleted partitions from digital media to extract the evidence and validate them.
• Helps you to identify the evidence quickly, and also allows you to estimate the potential impact of the malicious activity on the victim
• Producing a computer forensic report which offers a complete report on the investigation process.
• Preserving the evidence by following the chain of custody.
