A formal declaration statement signed and dated by the forensic examiner. 5. Setting Up a Digital Forensics Lab Environment
Navigate the left sidebar tree to view existing files, deleted directories (marked with a red 'X'), and unallocated space.
Upon completion, a status window will appear showing computed hash values. The investigator must document the following in their lab report: e80b5017098950fc58aad83c8c148ca2 MD5 Hash of Created Image: e80b5017098950fc58aad83c8c148ca2 Verification Status: MATCH / SUCCESS Run a cryptographic hashing algorithm (SHA-256 or MD5)
Open the application and navigate to File > Create Disk Image .
Cyber attacks often occur across networks rather than localized machines. Network forensics focuses on capturing and analyzing volatile data in transit.

The Chain of Custody is a chronological paper trail documenting the seizure, custody, control, transfer, and analysis of physical and digital evidence. Every single transfer must document: The exact date and time of transfer.
A table documenting device model numbers, serial numbers, capacity, hash values upon arrival, and assigned evidence tracking IDs.
Capturing live traffic or analyzing Packet Capture (PCAP) files to identify malicious payloads, command-and-control (C2) communication, or data exfiltration.
: This foundational module covers the definition, scope, and legal principles of digital forensics. It introduces the scientific method as applied to digital evidence, including important legal and ethical considerations for investigators. Students learn about different types of cybercrimes, such as network intrusions, data breaches, and fraud, setting the stage for practical applications. Cyber attacks often occur across networks rather than
: The manual delves into the artifacts left behind by various operating systems. For Windows systems, this includes the analysis of the Registry (for user activity, connected devices, and program execution), Event Logs (for system and security events), and prefetch files (for application execution history). For Linux-based systems, which are the foundation of many free forensic tools, the manual emphasizes command-line analysis, file system navigation, and the use of command-line forensic suites.
Deploy SIFT Workstation (SANS Investigative Forensic Toolkit) or TSIOS / Kali Linux as dedicated forensic operating systems pre-loaded with investigative tools.
A well-prepared lab manual should provide an overview of both open-source and industry-standard commercial tools. Type / License Primary Use Case Open Source
In the modern era, crime scenes no longer require a chalk outline on a sidewalk. They exist in volatile memory, hidden partitions, encrypted drives, and cloud servers. As cyber threats evolve from lone hackers to state-sponsored actors and ransomware gangs, the demand for structured, repeatable, and legally sound investigation methods has exploded.
