Course 36 - Windows Forensics and Tools | Episode 2: Windows Forensic Imaging and Drive Nomenclature

In this lesson, you’ll learn about: Windows forensic imaging and data structure fundamentals1. What is Forensic Imaging?A bit-by-bit, sector-by-sector copy of a storage deviceCaptures everything, not just visible files🔹 What it IncludesActive files and foldersDeleted filesUnallocated spaceSlack space👉 Key Difference:Not a backup → it is an exact forensic replica2. Why Forensic Imaging MattersPreserves original evidencePrevents modification of:File timestampsMetadata👉 Legal Importance:Required for court-admissible investigations3. Physical vs Logical Drives (Windows Naming)🔹 Physical DrivesIdentified as:Disk 0Disk 1Represent actual hardware🔹 Logical DrivesRepresent partitions using letters:C:D:E:👉 Analogy:Physical disk → entire cabinetLogical drives → drawers inside the cabinet🔹 Historical NoteA: and B: reserved for floppy disks4. File System Hierarchy🔹 Structure LevelsVolume (highest level)PartitionDirectory (folder)File🔹 File DefinitionA logical grouping of related data👉 Key Insight:Understanding hierarchy helps in locating and analyzing evidence5. Processes and Threads (Execution Basics)Process → running programThread → smallest execution unit within a process👉 Why it matters:Helps track:Program executionMalicious activity6. Data Integrity & Verification🔹 Hashing ConceptGenerate a unique fingerprint for data🔹 Algorithm ExampleMD5 hash🔹 Key PropertiesSame file → same hashRename file → hash unchangedChange 1 bit → completely different hash👉 Use Case:Verify forensic image integrity7. Chain of Trust in ForensicsAcquire image → generate hashAnalyze copy → compare hash again👉 Goal:Ensure no tampering occurredKey TakeawaysForensic imaging captures complete disk data, including hidden contentPhysical and logical drives represent different abstraction layersFile systems follow a structured hierarchyHashing ensures data integrity and authenticityEven a tiny change in data invalidates evidenceBig PictureForensic imaging helps you:👉 Move from raw disk → verified evidence copyMental ModelDisk → Image → Hash → Analyze → VerifyYou can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/cybercode_academy
