Digital-Forensics-in-Cybersecurity Exam Dumps - Digital Forensics in Cybersecurity (D431/C840DQO1) Course Exam

Comprehensive and Detailed Explanation From Exact Extract:

The/etcdirectory on Unix-based systems, including macOS, contains important system configuration files and scripts. It is the standard location for system-wide configuration data.

/varcontains variable data like logs and spool files.

/bincontains essential binary executables.

/cfgis not a standard directory in macOS.

This is standard Unix/Linux directory structure knowledge and is reflected in NIST and forensic references for macOS.

The Chain of Custody (CoC) is the documented and unbroken transfer record of evidence handling, from seizure to presentation in court. It ensures that the evidence has been preserved, controlled, and protected from tampering or alteration.

Evidence record documents evidence details but is less formal than CoC.

Event log and audit log are system-generated records and do not replace the formal CoC.

CoC is a fundamental forensic principle as outlined by NIST SP 800-86 and the Scientific Working Group on Digital Evidence (SWGDE) best practices, ensuring evidence admissibility and reliability in legal proceedings.

Firewall logs record network traffic to and from the messaging server and can provide evidence of unauthorized access attempts or data exfiltration. Collecting these logs allows investigators to reconstruct the attack timeline and identify the attacker’s IP address and methods.

Firewall logs are critical for network-level forensics.

According to NIST SP 800-86, log files provide primary evidence for intrusion investigations.

Comprehensive and Detailed Explanation From Exact Extract:

The ipconfig command executed at a Windows command prompt displays detailed network configuration information such as IP addresses, subnet masks, and default gateways. Collecting this information prior to seizure preserves volatile evidence relevant to the investigation.

Documenting network settings supports the understanding of the suspect system's connectivity at the time of seizure.

NIST recommends capturing volatile data (including network configuration) before shutting down or disconnecting a suspect machine.

Comprehensive and Detailed Explanation From Exact Extract:

SATA (Serial ATA) refers to an interface standard commonly used for connecting magnetic hard disk drives (HDDs) and solid-state drives (SSDs) to a computer. The term SATA itself describes the connection, but most HDDs that use SATA as an interface are magnetic drives.

CD-ROM and Blu-ray are optical storage media, not magnetic.

SSD (Solid State Drive) uses flash memory, not magnetic storage.

Magnetic drives rely on spinning magnetic platters, which are typically connected via SATA or other interfaces.

This differentiation is emphasized in digital forensic training and hardware documentation, including those from NIST and forensic hardware textbooks.

Comprehensive and Detailed Explanation From Exact Extract:

Disconnecting the computer from the network by unplugging the Ethernet cable prevents further spread of malware and stops external communication that could lead to data exfiltration. This containment step is vital before further evidence collection.

Maintaining system power preserves volatile memory.

Network disconnection is recommended by incident response guidelines.

Snow is a specialized steganalysis tool that detects and extracts hidden data encoded in whitespace characters within text files and other mediums. It is widely used in digital forensic investigations for detecting covert data hiding methods such as whitespace steganography.

Data Doctor is a general data recovery tool, not specialized in steganalysis.

FTK is a general forensic suite, not specifically designed for steganography detection.

MP3Stego is focused on audio steganography.

NIST and digital forensics literature recognize Snow as a valuable tool in workflows designed to detect hidden data in text or similar carriers.

Comprehensive and Detailed Explanation From Exact Extract:

Magnetic hard drives generally have a lower cost per gigabyte compared to solid-state drives (SSDs). However, they are more susceptible to mechanical damage and slower in data access.

SSDs have no moving parts and provide better durability and speed but at a higher price.

Forensics practitioners consider these differences during evidence acquisition.
