Project Design and Management in Mobile Forensic Assignment | Online Homework Help

 

3. Chapter 3. Project Design and Management

 

3.0 introduction

 

Mobile forensic are types of digital forensic which occur over mobile devices and facilitate extraction of digital evidence in the event of crime committed using mobile devices (Arora & Gigras, 2020). This thesis will focus on tools that used in android forensics to get data acquisition. Furthermore, will use six open source applications on Linux operating system. as well will use one application for analyses. The applications are: WhatsApp Forensic, Android Keystore, PyADB, Android Backup Extractor, OpenMF and Andriller. Each has different functionality and methods for data acquisition which will explain in details on this thesis with Autopsy tool.

 

3.1 Methodology

 

Software Development Life Cycle (SDLC) Model refers to a conceptual framework which encompasses all the activities engaged during software development project (Lemke, 2018). The major activities in a SDLC model include identification of all the requirements, the implementation of the requirements and finally software deployment (Kudo, et al., 2019). In project thesis, I will use SDLC model mmethodology to complete the main goal of the project. More details in appendix (A). There are five phases related to the model which are: –

1. First phase requirements analysis. During this process, will determine the project requirements for open-source mobile forensics tools
2. Next Design Phase, which depend on above reequipments on previous stage. According to that, will design a basic design of the project system
3. After complete and confirm the system design and system functionality, the next phase is implementation. In this phase will install all OS required, applications and any other software’s for the project.
4. Then, verification phase. During this phase will apply multi tests on forensics tools as well for tools integrity. That to confirm it meets the requirements and can interface with other software (Olszewska & Allison, 2018).
5. Last phase, maintenances which is ensure that all tools are work with result and properly. As well for future enhancement and maintenance (Chernyshev et al., 2017).

3.3 Android data acquisition process flow

 

Short prograph ( 5-6  lines ) from : Data extraction techniques – page 342…. You may start  prograph by :

• Android Data acquisition is kind of a process which allow to  extracte data from mobile

And then mention 3 types of extraction

 

 

3.4 Manual data extraction  ( 4-5 lines ) Page 344 only

 

 

3.5 Logical data extraction ( 4-5 lines ) Page 346 only… in the end I want you mention this : logical data  use an applications to perform the result

 

 

3,6 physical data extraction ( 4-5 lines )  you can check this web as a referance : https://www.milwforensics.com/PrivateInvestigatorReviews-logicalPhysicalExtraction    ( don’t forget to add this link to references )

3.4 data analysis process diagram

Data analysis is a process to analysis all data acquired aby different applications. during using android application, a lot of sensitive information are stored in internal memory. by using different forensics tools the examiner can get access data that stored internally .After data been collected from six open sources tools,  autopsy will be used for data analysis.

In yellow cooler I paraphrase it from this book :

Practical mobile forensics :Dive into mobile  forensics  on IOS, Android ,windows  and blackberry  devices  with this action-packed  practical guide

Authors : Satish bommisetty, Rohit Tamma , Heather Mahalik

Page : 380

 

Figure  : Flowchart of  data analysis process

 

Through analysis process  the examiner can analysis different  data that acquired . Autopsy application is open source tool which can analysis android image . the application provide different model  such : Timeline Analysis , Hash Filtering, Keyword Search, Web Artifacts, Data Carving, and Multimedia

 

In the yellow color I paraphrase it from this book :
