Understanding Disk Imaging Purpose

What is the primary purpose of creating a disk image in a cybersecurity investigation?

A To encrypt the disk contents to protect data from hackers

B To compress files on the disk to save storage space

C To create an exact copy of the storage device for analysis without altering the original data

D To delete all data on the disk to prevent unauthorized access

💡 Hint

Think about why investigators want to keep the original data safe during analysis.

Disk imaging creates a bit-for-bit copy of the storage device, preserving the original data intact for forensic analysis.

File System Types in Disk Imaging

Which file system type is most commonly encountered when performing disk imaging on Windows systems?

A EXT4

B FAT32

C HFS+

D NTFS

💡 Hint

Consider the default file system used by modern Windows operating systems.

NTFS (New Technology File System) is the standard file system for Windows NT and later versions.

🔍 Analysis

Interpreting Disk Image Hash Values

After creating a disk image, an investigator calculates its hash value. What does a matching hash value between the original disk and the image indicate?

A The disk image is an exact, unaltered copy of the original disk

B The disk image has been compressed to reduce size

C The disk image contains corrupted data

D The disk image is encrypted

💡 Hint

Hash values are used to verify data integrity.

If the hash values match, it confirms the disk image is identical to the original disk with no changes.

❓ Comparison

Comparing Logical vs Physical Disk Imaging

Which statement correctly distinguishes logical disk imaging from physical disk imaging?

A Logical imaging copies only active files and folders, while physical imaging copies the entire disk sector by sector

B Logical imaging copies the entire disk sector by sector, while physical imaging copies only active files

C Logical imaging encrypts data, physical imaging compresses data

D Logical imaging is faster because it copies the entire disk, physical imaging is slower because it copies only files

💡 Hint

Think about what each imaging type includes in the copy.

Logical imaging captures only the files and folders visible to the operating system, while physical imaging copies every sector including deleted and hidden data.

Choosing the Best Tool for Disk Imaging

An investigator needs to create a forensic disk image that preserves deleted files and slack space for a Windows NTFS drive. Which tool is best suited for this task?

A Windows File Explorer

B FTK Imager

C Disk Cleanup Utility

D Notepad

💡 Hint

Consider tools designed specifically for forensic imaging and data preservation.

FTK Imager is a forensic tool that creates exact disk images including deleted files and slack space, essential for investigations.
