Disk imaging and analysis in Cybersecurity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is disk imaging in cybersecurity?

Disk imaging is the process of creating an exact copy of a computer's storage device, including all files, folders, and system data, to preserve evidence for analysis.

Why is disk imaging important in digital forensics?

Disk imaging preserves the original data without altering it, allowing investigators to analyze the copy while keeping the original evidence intact and admissible in court.

What is the difference between a logical image and a physical image?

A logical image copies only the active files and folders visible to the operating system, while a physical image copies the entire storage device bit-by-bit, including deleted and hidden data.

Name a common tool used for disk imaging.

One common tool is 'dd', a command-line utility that creates bit-for-bit copies of storage devices for forensic analysis.

intermediate

What is the purpose of hash values in disk imaging?

Hash values verify the integrity of the disk image by ensuring the copied data matches the original exactly, detecting any changes or tampering.

What does disk imaging create?

A An exact copy of a storage device

B A summary report of files

C A backup of only documents

D A list of installed programs

Disk imaging creates an exact copy of the entire storage device, preserving all data.

Which type of disk image includes deleted files?

A Physical image

B Logical image

C Incremental backup

D Differential backup

Physical images copy the entire device bit-by-bit, including deleted and hidden data.

Why are hash values used in disk imaging?

A To compress the image

B To speed up copying

C To verify data integrity

D To encrypt the data

Hash values help verify that the copied data matches the original exactly.

Which tool is commonly used for creating disk images?

A Photoshop

B dd

C Excel

D Notepad

'dd' is a command-line tool used to create bit-for-bit copies of storage devices.

What is the main goal of disk imaging in forensics?

A To delete unnecessary files

B To install new software

C To speed up the computer

D To preserve evidence without alteration

Disk imaging preserves evidence exactly as it is, preventing changes during analysis.
