EnCE File Systems & Artifact Examination

Question 1

What is the role of a file system in digital storage?

Accepted Answer

Manages and organizes files

Answer

A file system is a method and data structure that an operating system uses to control how data is stored and retrieved on a storage device. It organizes files and directories, tracks their locations, manages access permissions, and ensures efficient storage and retrieval of information, making it fundamental to digital storage.

Question 2

Which file systems are commonly examined in forensic cases?

Accepted Answer

NTFS, FAT32, exFAT

Answer

NTFS, FAT32, and exFAT are common file systems encountered in digital forensic investigations because they are widely used across various operating systems and storage devices. NTFS is prevalent in Windows, FAT32 is common on older systems and removable media, and exFAT is often used for larger removable storage, each requiring specific forensic analysis techniques.

Question 3

What are file system artifacts?

Accepted Answer

Metadata and system records

Answer

File system artifacts are remnants or records left behind by operating system activities and user actions on a storage device. These include crucial metadata, such as file creation/modification times, sizes, and permissions, as well as various system records like journal files and registry entries. They are invaluable in forensic investigations, providing contextual information about system usage and user behavior.

Question 4

What does the Master File Table (MFT) store?

Accepted Answer

File metadata in NTFS

Answer

The Master File Table (MFT) is a fundamental component of the NTFS file system, primarily used by Windows operating systems. It functions as a comprehensive database that stores critical metadata for every file and directory on the volume. This metadata encompasses essential details like file names, sizes, timestamps, security attributes, and the physical location of the file's data on the disk.

Question 5

What is slack space in a file system?

Accepted Answer

Unallocated leftover data

Answer

Slack space refers to the unused portion of a disk cluster that remains after a file has been written to it. Since files rarely perfectly fill an entire cluster, the leftover space is termed 'slack.' This area can contain residual data from previously stored files or system processes, making it a significant source of potential forensic evidence for investigators.
