Digital Forensics Processing and Procedures

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.

In this digital forensic tutorial, you will learn: What is Digital Forensics? In the first computer crime was recognized in the Florida Computer Crime Act. Francis Galton - : Conducted first recorded study of fingerprints In , the term Computer Forensics was used in academic literature. In , Simson Garfinkel identified issues facing digital investigations.

Objectives of computer forensics Here are the essential objectives of using 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. Process of Digital forensics Digital forensics entails the following steps: Identification Preservation Analysis Documentation Presentation Process of Digital Forensics Let's study each in detail Identification It 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. Preservation In 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.

Analysis In 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. Documentation In 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.

Presentation In 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 Forensics Three 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 Forensics Deals 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. Challenges faced by Digital Forensics Here, are major challenges faced by the Digital Forensic: The increase of PC's and extensive use of internet access Easy availability of hacking tools Lack of physical evidence makes prosecution difficult.

The large amount of storage space into Terabytes that makes this investigation job difficult. Any technological changes require an upgrade or changes to solutions. To produce evidence in the court, which can lead to the punishment of the culprit. It helps the companies to capture important information if their computer systems or networks are compromised. Efficiently tracks down cybercriminals from anywhere in the world.

Helps to protect the organization's money and valuable time. Allows to extract, process, and interpret the factual evidence, so it proves the cybercriminal action's in the court.

However, it is must be proved that there is no tampering Producing electronic records and storing them is an extremely costly affair Legal practitioners must have extensive computer knowledge Need to produce authentic and convincing evidence If the tool used for digital forensic is not according to specified standards, then in the court of law, the evidence can be disapproved by justice. Lack of technical knowledge by the investigating officer might not offer the desired result Summary: Digital Forensics is the preservation, identification, extraction, and documentation of computer evidence which can be used in the court of law Process of Digital forensics includes 1 Identification, 2 Preservation, 3 Analysis, 4 Documentation and, 5 Presentation Different types of Digital Forensics are Disk Forensics, Network Forensics, Wireless Forensics, Database Forensics, Malware Forensics, Email Forensics, Memory Forensics, etc.

Digital forensics sometimes known as digital forensic science is a branch of forensic science encompassing the recovery and investigation of material found in digital devices, often in relation to computer crime. Digital forensics investigations have a variety of applications. The most common is to support or refute a hypothesis before criminal or civil courts. Criminal cases involve the alleged breaking of laws that are defined by legislation and that are enforced by the police and prosecuted by the state, such as murder, theft and assault against the person. Civil cases on the other hand deal with protecting the rights and property of individuals often associated with family disputes but may also be concerned with contractual disputes between commercial entities where a form of digital forensics referred to as electronic discovery ediscovery may be involved. Forensics may also feature in the private sector; such as during internal corporate investigations or intrusion investigation a specialist probe into the nature and extent of an unauthorized network intrusion. The technical aspect of an investigation is divided into several sub-branches, relating to the type of digital devices involved; computer forensics, network forensics , forensic data analysis and mobile device forensics.
