If you’ve made it to level II of Computer Forensics and Security, you already know that “deleting” a file is about as effective as hiding a neon sign under a bedsheet. You’ve moved past the basics of installing an antivirus; now, you’re in the world of unallocated space, volatile memory analysis, and the legal tightrope of the chain of custody.

Past Paper On Computer Forensic And Security II For Revision
Above is the exam paper download link
Computer Forensics II isn’t just about finding the “smoking gun”—it’s about proving, in a way that holds up in a court of law, that the gun belonged to the suspect and that no one else could have fired it. It is a rigorous, technical, and highly procedural discipline.
To help you move from a “curious hobbyist” to a “certified investigator,” we’ve tackled the complex questions that typically define the level II syllabus. To round off your study session, you can download our curated Computer Forensics and Security II past paper at the bottom of this page.
The Forensic Q&A: Deep-Dive Revision
Q: Why is “Live Acquisition” becoming more important than “Static Acquisition”? In the old days, you’d pull the plug on a PC and image the hard drive. That’s Static Acquisition. But today, with full-disk encryption (like BitLocker), pulling the plug might lock the data forever. Live Acquisition involves capturing the RAM (Random Access Memory) while the computer is still running. If you don’t capture the volatile data now, you lose encryption keys, open network connections, and running processes that disappear the moment the power cuts out.
Q: What is “Steganography,” and how do you spot it in an investigation? Steganography is the art of hiding a message inside another file—like embedding a text document inside a JPEG of a cat. To a standard file explorer, it just looks like a picture. Forensic investigators look for unusual file sizes or use “Statistical Steganalysis” to find patterns in the pixels that shouldn’t be there. In your exam, distinguish this from Encryption, which hides the meaning of a message, whereas steganography hides the existence of the message.
Q: How do “File Signatures” help when a suspect renames their files? A suspect might rename contract.pdf to system_log.txt to hide it. However, every file type has a “Magic Number” or a header in its hex code. A PDF always starts with %PDF. Forensic software ignores the file extension and looks at the signature to identify the true nature of the file.
Q: What is the significance of the “Registry” in a Windows forensic exam? The Windows Registry is a goldmine. It tracks recently opened files (MRU lists), connected USB devices, and even the last time a specific program was executed. If a suspect claims they “never used that thumb drive,” the Registry will usually prove otherwise by showing the device’s unique serial number and the exact timestamp it was plugged in.
Strategy: How to Use the Past Paper for Peak Performance
Don’t just read the questions and think, “I’ve seen that in a slide.” Forensics is a practical science. Here is how to use the download below:
-
The Case Study Logic: Level II papers often give you a scenario: “A laptop is found in sleep mode at a crime scene. What are your first three steps?” Practice writing these out. (Hint: Secure the scene, document the state, and decide between live or dead acquisition).
-
The Tools Knowledge: Be ready to explain when you’d use FTK Imager versus Autopsy or Volatility. Know the difference between a bit-stream image (an exact clone) and a simple file copy.
-
The Legal Framework: Security II often tests your knowledge of local and international laws (like the Fourth Amendment in the US or the Data Protection Act). Know the difference between a “Private” and “Public” sector investigation.
Ready to Prove Your Case?
You can memorize definitions all day, but Computer Forensics II tests your ability to think under pressure. It’s about the methodology. Working through a past paper allows you to see the patterns in how examiners try to “trip you up” with procedural nuances.
We’ve put together a comprehensive past paper that covers everything from anti-forensic techniques to mobile device seizure and network traffic analysis.
