What type of evidence can be identified and collected from digital devices?
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. Show
Digital Forensics helps the forensic team to analyzes, inspect, identifies, and preserve the digital evidence residing on various types of electronic devices. In this digital forensic tutorial, you will learn:
History of Digital forensicsHere, are important landmarks from the history of Digital Forensics:
Objectives of computer forensicsHere are the essential objectives of using Computer forensics:
Process of Digital forensicsDigital forensics entails the following steps:
Let’s study each in detail IdentificationIt is the first step in the forensic process. The identification process mainly includes things like what evidence is present, where it is stored, and lastly, how it is stored (in which format). Electronic storage media can be personal computers, Mobile phones, PDAs, etc. PreservationIn this phase, data is isolated, secured, and preserved. It includes preventing people from using the digital device so that digital evidence is not tampered with. AnalysisIn this step, investigation agents reconstruct fragments of data and draw conclusions based on evidence found. However, it might take numerous iterations of examination to support a specific crime theory. DocumentationIn this process, a record of all the visible data must be created. It helps in recreating the crime scene and reviewing it. It Involves proper documentation of the crime scene along with photographing, sketching, and crime-scene mapping. PresentationIn this last step, the process of summarization and explanation of conclusions is done. However, it should be written in a layperson’s terms using abstracted terminologies. All abstracted terminologies should reference the specific details. Types of Digital ForensicsThree types of digital forensics are: Disk Forensics:It deals with extracting data from storage media by searching active, modified, or deleted files. Network Forensics:It is a sub-branch of digital forensics. It is related to monitoring and analysis of computer network traffic to collect important information and legal evidence. Wireless Forensics:It is a division of network forensics. The main aim of wireless forensics is to offers the tools need to collect and analyze the data from wireless network traffic. Database Forensics:It is a branch of digital forensics relating to the study and examination of databases and their related metadata. Malware Forensics:This branch deals with the identification of malicious code, to study their payload, viruses, worms, etc. Email ForensicsDeals with recovery and analysis of emails, including deleted emails, calendars, and contacts. Memory Forensics:It deals with collecting data from system memory (system registers, cache, RAM) in raw form and then carving the data from Raw dump. Mobile Phone Forensics:It mainly deals with the examination and analysis of mobile devices. It helps to retrieve phone and SIM contacts, call logs, incoming, and outgoing SMS/MMS, Audio, videos, etc. What are the types of digital evidence?Digital Evidence
This includes email, text messages, instant messages, social media posts, files and documents extracted from hard drives, electronic financial transactions, audio files, and video files.
What are 3 sources of digital evidence?There are many sources of digital evidence, but for the purposes of this publication, the topic is divided into three major forensic categories of devices where evidence can be found: Internet-based, stand-alone computers or devices, and mobile devices.
What are the two types of digital evidences?What are the 8 Types of Digital Evidence?. Video footage and images.. Archives.. Active data.. Metadata.. Residual data.. Volatile data.. Replicant data.. What type of forensics is used to identify collect and analyze evidence from electronic devices?Digital forensics is the practice of identifying, acquiring, and analyzing electronic evidence. Today almost all criminal activity has a digital forensics element, and digital forensics experts provide critical assistance to police investigations. Digital forensic data is commonly used in court proceedings.
