Fundamental Computer Investigation Guide For Windows

Fundamental Computer Investigation Guide for Windows: A Step-by-Step Tutorial

Computer investigations are essential for gathering digital evidence in cases involving cybercrime, fraud, hacking, or other illegal activities. However, conducting a computer investigation can be challenging, especially for beginners who are not familiar with the tools and techniques involved. That's why we have created this fundamental computer investigation guide for Windows, which will walk you through the basic steps of performing a computer forensic analysis on a Windows system.

In this guide, you will learn how to:

Prepare your investigation environment and tools

Acquire and preserve the digital evidence from the target computer

Analyze the evidence using various forensic tools and methods

Generate and present a forensic report based on your findings

By following this guide, you will be able to conduct a computer investigation in a systematic and professional manner, and gain valuable skills and knowledge in the field of digital forensics. Let's get started!

Step 1: Prepare Your Investigation Environment and Tools

Before you start your computer investigation, you need to prepare your investigation environment and tools. This includes setting up a secure and isolated workspace, obtaining the necessary authorization and documentation, and acquiring the appropriate forensic tools and software.

Your investigation environment should be a separate room or area that is protected from unauthorized access, interference, or contamination. You should also ensure that you have a reliable power source, internet connection, and backup system. You should avoid using any personal devices or accounts during your investigation, as they may compromise your evidence or expose your identity.

Your investigation tools should include a forensic workstation, which is a dedicated computer that is used for forensic analysis. Your forensic workstation should have enough storage space, memory, processing power, and ports to handle the evidence data. You should also install various forensic software and tools on your forensic workstation, such as:

A write blocker, which is a device that prevents any changes to the evidence data when it is connected to your forensic workstation.

A disk imaging tool, which is a software that creates an exact copy of the evidence data from the target computer.

A disk analysis tool, which is a software that allows you to examine the contents and structure of the evidence data.

A file recovery tool, which is a software that helps you recover deleted or hidden files from the evidence data.

A file carving tool, which is a software that extracts files from unallocated or damaged sectors of the evidence data.

A registry analysis tool, which is a software that analyzes the Windows registry files from the evidence data.

A timeline analysis tool, which is a software that creates a chronological overview of the events and activities on the target computer.

A malware analysis tool, which is a software that detects and analyzes any malicious software on the target computer.

A network analysis tool, which is a software that monitors and captures the network traffic on the target computer.

A password cracking tool, which is a software that helps you bypass or recover any passwords on the target computer.

A hash calculator tool, which is a software that generates hash values for the evidence data to verify its integrity.

You can find many free or open-source forensic tools online, such as FTK Imager, Autopsy, Recuva, Scalpel, RegRipper, Log2Timeline, Cuckoo Sandbox, Wireshark, John the Ripper, and HashCalc. However, you should always verify the source and quality of these tools before using them.

Step 2: Acquire and Preserve the Digital Evidence from the Target Computer

After you have prepared your investigation environment and tools,

you need to acquire and preserve the digital evidence from

the target computer. This involves identifying,

collecting,

and copying

the relevant data from

the target computer

to your forensic workstation,

while maintaining

the chain of custody

and integrity

of the evidence.

To identify

the relevant data,

you need to determine

the scope

and objectives

of your investigation,

and what type

of information

you are looking for.

For example,

you may want to find out

the identity

and location

of the suspect,

the nature

and extent

of their activities,

the motive

and methods

of their actions,
