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 device * Captures everything, not just visible files 🔹 What it Includes * Active files and folders * Deleted files * Unallocated space * Slack space 👉 Key Difference: * Not a backup → it is an exact forensic replica 2. Why Forensic Imaging Matters * Preserves original evidence * Prevents modification of: * File timestamps * Metadata 👉 Legal Importance: * Required for court-admissible investigations 3. Physical vs Logical Drives (Windows Naming)🔹 Physical Drives * Identified as: * Disk 0 * Disk 1 * Represent actual hardware 🔹 Logical Drives * Represent partitions using letters: * C: * D: * E: 👉 Analogy: * Physical disk → entire cabinet * Logical drives → drawers inside the cabinet 🔹 Historical Note * A: and B: reserved for floppy disks 4. File System Hierarchy🔹 Structure Levels 1. Volume (highest level) 2. Partition 3. Directory (folder) 4. File 🔹 File Definition * A logical grouping of related data 👉 Key Insight: * Understanding hierarchy helps in locating and analyzing evidence 5. Processes and Threads (Execution Basics) * Process → running program * Thread → smallest execution unit within a process 👉 Why it matters: * Helps track: * Program execution * Malicious activity 6. Data Integrity & Verification🔹 Hashing Concept * Generate a unique fingerprint for data 🔹 Algorithm Example * MD5 hash 🔹 Key Properties * Same file → same hash * Rename file → hash unchanged * Change 1 bit → completely different hash 👉 Use Case: * Verify forensic image integrity 7. Chain of Trust in Forensics * Acquire image → generate hash * Analyze copy → compare hash again 👉 Goal: * Ensure no tampering occurred Key Takeaways * Forensic imaging captures complete disk data, including hidden content * Physical and logical drives represent different abstraction layers * File systems follow a structured hierarchy * Hashing ensures data integrity and authenticity * Even a tiny change in data invalidates evidence Big PictureForensic imaging helps you:👉 Move from raw disk → verified evidence copyMental Model * Disk → Image → Hash → Analyze → Verify You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy [https://linktr.ee/cybercode_academy]
