science that focuses on locating, acquiring, processing, analyzing, and reporting on electronically stored data. This subject will help students to understand the principles and different tools of digital forensics.
Digital forensics is a field that deals with recovering digital evidence from computer systems. It is an assignment that asks students to create a digital forensic report on a given topic.
Digital forensics is the process of collecting and analyzing digital evidence from a computer or other electronic device. The term is used in law enforcement, investigations, and intelligence gathering. Some of the type of Digital Forensics ase as follows:-
Network Forensics
It is a sub-discipline of digital forensic. It deals with collecting critical information and legal evidence by monitoring and analysing computer network traffic.
Mobile Forensics
It mostly focuses on mobile device examination and analysis. It allows you to retrieve phone and SIM contacts, call records, incoming and outgoing SMS/MMS, audio, and video files, among other things.
Wireless Forensics
It’s a network forensics section. Wireless forensics’ major goal is to provide the tools needed to collect and analyse data from wireless network traffic.
Database Forensics
It’s a subset of digital forensics that deals with the investigation and analysis of databases and their related metadata.

Digital Forensics: Challenges
List of Challenges Faced by Digital Forensics:
The rise in the number of personal computers (PCs) and the widespread use of the internet.
Hacking tools are readily available.
Prosecution is difficult due to a lack of physical proof.
Any technology advancement necessitates a solution upgrade or modification.
Rise of anti forensics techniques.
Some of the topics included in the unit are:
Threats that modern network infrastructure face in terms of security
Implementation of forensic analysis
How to collect forensic material for expert analysis
How to overcome legal, ethical and professional problems in the field of Information security
Important Terms:
The process of capturing data from the world around us so that it may be presented, processed, and stored in a computer is known as Data Acquisition.
The practice of systematically applying statistical and/or logical approaches to describe and demonstrate, condense and recapitulate, and assess data is known as Data Analysis.
Data validation means checking the accuracy and quality of source data before using, importing or otherwise processing data.
ASSESSMENT DETAILS
Learning Outcomes
Apply socio-technical contexts in analysing the digital forensic evidence. Investigate the nature and extent of a network intrusion. Demonstrate competence in applying industry-standard forensic analysis techniques. Record and document Digital Forensics in social media.
Assignment Description
This Assignment is Divided Into 2 Parts: Part A: It focuses on the recent digital forensic crime Part B: Prepare a forensic image, forensic analysis and data validation
Part A Digital Forensic Crime
You need to research one recent digital forensics crime that requires digital forensics investigation, such as malware, embezzlement, extortion, cyberbullying, murder, kidnap, drug trafficking, intellectual property theft, espionage, employment misconduct, fraud, forgeries, inappropriate email and internet use in the workplace. For this part , you will write a 500 – 1000 words report that addresses the necessary steps to ensure that digital evidence is collected, preserved, imaged, and can be examined.
Topic 1 – Network Forensics: Challenges and Approaches
Write a group report including the following sections.
History and background of the network forensics.
Discusses the different tools and techniques available to conduct network forensics.
Describe forensic approaches for the network forensics.
Address the issues of network forensics.
Discuss the type of evidence that could be found with challenges in network forensics.
Analyse and discuss the significance of digital forensics for the network forensics.
Analyse and review the existing techniques for network forensics and identify among them the best technique.
Examine the performance of three network forensic tools.
Analyse the challenges and Propose/ Review some solutions that can be taken to overcome these challenges.
Investigate the relevant forensic tools that can be used to address the challenges of the above case.
Propose/ Review some solutions that can be taken to overcome these challenges.
Topic 2 – Mobile Forensics: Challenges and Approaches
Your article should cover the following points:
History and background of mobile forensics.
Discuss the type of evidence that could be found with challenges in mobile computing.
Analyse and discuss the significance of digital forensics for mobile computing.
Discuss the digital forensics tools that could be useful for doing a mobile forensic investigation.
Provides an overview of the capabilities of three popular mobile forensic tools on three mobile phones based on iOS and Android operating systems.
Describes the limitations of each, three forensics tools, in accessing contacts, call history, message data (SMS, MMS and emails), media files and other data based on iOS and Android.
Describe forensic approaches for mobile forensics.
Review the mobile Forensics Issues and challenges.
Describe the issues in mobile computing that would affect the forensic investigation.
Examined the performance of three mobile forensic tools.
Discussion of technologies and techniques in the existing solutions and future works.
Findings and implications for digital forensic practitioners.
Propose/ Review a number of solutions that can be taken to overcome these challenges.
Topic 3 – Cloud Forensics: Challenges and Approaches
Write a research survey of the forensic challenges in cloud computing and analyse their most recent solutions and developments.
Your article should cover the following points:
Describe forensic approaches for cloud forensics.
Discuss the type of evidence that could be found with challenges in Cloud computing.
Analyse and discuss the significance of digital forensics for Cloud computing.
Review the Cloud Forensics Issues & Challenges.
Describe the issues in cloud computing that would affect the forensic investigation.
List of challenges facing the cloud forensic investigation .
List the digital forensics tools that could be useful for doing cloud forensics investigation.
Discussion of technologies and techniques in the existing solutions and future works.
Propose/ Review a number of solutions that can be taken to overcome these challenges.
Prepare a report on the following:
1. Provide a detailed description of the case. a. Summary of the offence being investigated. b. Report who was involved in the crime, i.e. who was the criminal(s), the suspect(s) and the victim(s)? c. Identify and report what type of evidence was used in the criminal investigation of the case; d. Explain two acquisition methods that you should use in this case study. e. Discuss some options that can be used for preserving the data.
2. Explain the importance of a chain of custody for digital forensic evidence. Be sure to explain the process of documenting, collecting and storing evidence from the crime scene you’re investigating (e.g. a laptop computer). Describe the consequences of not following a proper chain of custody.
3. Discuss the procedures for the preservation of evidence; be sure to connect this work with the chain of custody. Describe consequences of not carefully preserving evidence.
4. List and analyse the tools you will need in your investigation and the reason you chose those tools. Support this analysis with relevant research. Critically evaluate the forensic tool(s) and discuss their capacity in various categories of functions, including acquisition, validation, and verification, extraction, reconstruction, and reporting.
Part B Data Acquisition, Data Analysis and Data Validation
The objective of assignment part b is to acquire data from a drive, perform data recovery using different techniques and tools, analyse it and finally perform the validation of acquired data. In addition, students are required to properly document all steps in a report, the report should be formal so that it can be used in a legal process.
Make a group video demonstration of three digital forensics tools. Prepare slides (between 8 – 12 slides) for your video demonstration. As a team of five, create a 5 - 8 minutes video demo using Zoom application (along with presenters’ video) addressing the following tasks:
1. Analyse and discuss the importance of your selected digital forensics tools. 2. Perform three selected digital forensics tools. 3. Identify and discuss the strengths and weaknesses of each digital forensics’ tools. 4. Which digital forensics would you recommend? Justify your recommendation.
