Digital-Forensics-in-Cybersecurity Exam Dumps and Practice Questions

Comprehensive and Detailed Explanation From Exact Extract:

In incident response, after collecting volatile data (such as contents of RAM), the next priority is often to collect network-related evidence such as active network connections. Network connections can reveal ongoing communications, attacker activity, command and control channels, or data exfiltration paths.

Running processes and temporary data are also volatile but typically collected simultaneously or immediately after volatile memory.

File timestamps relate to non-volatile data and are collected later after volatile data acquisition to preserve evidence integrity.

This sequence is supported by NIST SP 800-86 and SANS Incident Handler's Handbook which emphasize the volatility of evidence and recommend capturing network state immediately after memory.

The chain of custody is a documented, chronological record detailing the seizure, custody, control, transfer, analysis, and disposition of evidence. Maintaining this record proves that the evidence was protected and unaltered, which is essential for court admissibility.

Each transfer or access must be logged with date, time, and handler.

Breaks in the chain can compromise the legal validity of evidence.

According to NIST and forensic best practices, the chain of custody documentation is mandatory for reliable evidence handling.

Bit-level (or bit-stream) copying captures every bit on the storage media, including files, deleted files, slack space (unused space within a cluster), and unallocated space. This ensures all digital evidence, including artifacts not visible at the OS level, is preserved for analysis.

Copying at the OS level captures only allocated files visible in the file system, missing deleted files and slack space.

Bit-level copying is a cornerstone of forensic best practices as specified in NIST SP 800-86 and SWGDE guidelines.

Timestamp changes and unnecessary information issues are secondary concerns compared to the completeness of evidence.

Steganography is used to save or embed secret data within another file or medium, allowing covert communication without alerting observers to the presence of the data.

The goal is to conceal, not highlight or delete data.

It does not erase or delete secret data; instead, it hides it.

This aligns with standard definitions in cybersecurity and forensic literature including NIST's cybersecurity frameworks.

The Windows Security Account Manager (SAM) file stores hashed passwords for local Windows user accounts. These hashes are used to authenticate users without storing plaintext passwords.

The SAM file stores local account password hashes, not network passwords.

Passwords are hashed (not encrypted) using algorithms like NTLM or LM hashes.

Network password management occurs elsewhere (e.g., Active Directory).

NIST SP 800-86 and standard Windows forensics texts explain that the SAM file contains hashed local account credentials critical for forensic investigations involving Windows systems.
