Why is forensically important to collect the time and date of victim machine?
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. Why is it important to make a forensic copy of a running computer's memory before it is switched off?A memory dump can contain valuable forensics data about the state of the system before an incident such as a crash or security compromise. Memory dumps contain RAM data that can be used to identify the cause of an incident and other key details about what happened.
Why is computer forensics important?Why is computer forensics important? In the civil and criminal justice system, computer forensics helps ensure the integrity of digital evidence presented in court cases.
Is it necessary for forensic examiners to understand how data is stored by various types of file systems?Learn Digital Forensics
The forensic examiner must understand OSs, file systems, and numerous tools required to perform a thorough forensic examination of the suspected machine. Modern OSs track a good deal of information that could become artifacts of evidentiary value on the eve of forensic examination.
What is computer forensics what important practices are followed in computer forensics?We define computer forensics as the discipline that combines elements of law and computer science to collect and analyze data from computer systems, networks, wireless communications, and storage devices in a way that is admissible as evidence in a court of law.
