Step1: Identification & Preparation

Step 1:Identification and preparation

Identification involves recognizing and documenting potential digital evidence, which includes identifying devices, storage media, and files that may contain relevant information. This step often involves creating a forensic image of the storage media to preserve the data for analysis.

Preparation involves ensuring that the digital evidence is collected and handled properly to maintain its integrity and admissibility in court. This includes using proper tools and techniques to collect and preserve the data, documenting the chain of custody, and ensuring that the evidence is not altered or destroyed during the collection process.

Both identification and preparation are critical to the success of a digital forensic investigation, as they lay the foundation for the analysis and interpretation of the data.

1. Identification &  Preparation: The first step is to identify the scope of the investigation and create a plan for the investigation. This includes identifying the type of device(s) that need to be investigated, the data that needs to be collected, and the tools and techniques that will be used.


The preparation step is a critical aspect of digital forensics investigations as it sets the foundation for the entire process. Here are some key elements of the preparation step:


1.1 Define the scope: The first step is to define the scope of the investigation. This includes”

· identifying the type of device(s) that need to be investigated

· The data that needs to be collected

· and the tools and techniques that will be used.


1.2 Identify stakeholders: It is important to identify all stakeholders involved in the investigation,

· including legal· IT· and business teams.

This ensures that everyone is on the same page regarding the investigation's goals, and all parties understand their roles and responsibilities.

1.3 Secure the evidence: It is crucial to ensure that the evidence is secured and not tampered with. This may involve

1.3.1 seizing and securing the device(s) in question

Seizing and securing the device(s) in question is a critical first step in digital forensics investigations. This involves physically taking possession of the device(s) and preventing any further access or modification of the data on the device(s) until a thorough analysis can be conducted.

The following are some general steps to consider when seizing and securing devices for digital forensics:


1.3.1.2 Obtain a legal warrant or consent to search from the owner or custodian of the device(s), if applicable.

1.3.1.2 Document the location of the device(s), its condition, and any relevant information, such as the device model, serial number, and operating system.

1.3.1.3 Take necessary steps to ensure the device(s) remain powered off, unplugged, and in a secure location to prevent any further data tampering or modification.

1.3.1.4 Create a forensic image or copy of the device(s) using specialized software and hardware tools to preserve the data in its original state.

1.3.1.5 Store the forensic image or copy of the device(s) in a secure location to maintain the chain of custody and prevent data loss or tampering.

1.3.1.5 Limit access to the forensic image or copy of the device(s) to authorized personnel only, and maintain detailed documentation of all actions taken during the investigation

  • disconnecting the device(s) from the network, and making copies of the data if necessary.

1.4 Determine the timeline: It is important to determine the timeline of the incident being investigated
  •  including when the incident occurred
  •  when the device(s) were last used
  •  and when the data was last accessed.


1.5 Select the tools: Depending on the scope of the investigation, specific tools and software may be required to collect, analyze, and preserve the data. It is essential to select the appropriate tools to ensure that the investigation is conducted thoroughly and accurately.

1.6 Document the process: Throughout the investigation, it is crucial to document each step taken to ensure that the process is transparent and defensible in court. This documentation should include details of the preparation, data collection, analysis, preservation, and presentation phases.

Chain of Custody – Digital Forensics

  Chain of Custody – Digital Forensics Chain of Custody refers to the logical sequence that records the sequence of custody, control, transfer, analysis and disposition of physical or electronic evidence in legal cases. Each step in the chain is essential as if broke, the evidence may be rendered inadmissible. Thus we can say that preserving the chain of custody is about following the correct and consistent procedure and hence ensuring the quality of evidence. The chain of custody in digital cyber forensics is also known as the paper trail or forensic link, or chronological documentation of the evidence. ·         Chain of custody indicates the collection, sequence of control, transfer and analysis. ·         It also documents details of each person who handled the evidence, date and time it was collected or transferred, and the purpose of the transfer. ·         It de...

Part 1: Introduction to Computer Forensics for Windows

  Part 1: Introduction to Computer Forensics for Windows: https://tryhackme.com/room/windowsforensics1 Microsoft Windows is by large the most used Desktop Operating System right now. Private users and Enterprises prefer it, and it currently holds roughly 80% of the Desktop market share. This means that it is important to know how to perform forensic analysis on Microsoft Windows for someone interested in Digital Forensics. In this module, we will learn about the different ways we can gather forensic data from the Windows Registry and make conclusions about the activity performed on a Windows system based on this data. In computer forensics, forensic artifacts can be small footprints of activity left on the computer system. On a Windows system, a person's actions can be traced back quite accurately using computer forensics because of the various artifacts a Windows system creates for a given activity. These artifacts often reside in locations 'normal' users won't t...

Step 2 : Collection & Preservation of evidence

Step 2 :  Collection  & Preservation of evidence   The collecting process in digital forensics is a critical phase of the investigation. It involves the systematic and careful acquisition of digital data from electronic devices or storage media in a manner that preserves the integrity and authenticity of the evidence. The following are the steps involved in the collecting process: Collection : This step involves the actual acquisition of the data from the device or storage media. This can be done by using a variety of techniques, including   Imaging : The first step in the collection process is to create a forensic image of the digital device or media that is being investigated. This involves creating an exact copy of the device or media, including all data, file systems, and metadata. The imaging process ensures that the original evidence is preserved and can be examined without altering it.  Live analysis: In some cases, it may be necessary to conduct...
