Vce Digital-Forensics-in-Cybersecurity Questions Latest

Comprehensive and Detailed Explanation From Exact Extract:

Netstatis a command-line network utility tool used to monitor active network connections, open ports, and network routing tables. In the context of detecting data exfiltration potentially using steganographic methods, netstat can help a forensic investigator identify suspicious or unauthorized network connections through which hidden data may be leaving an organization.

While netstat itself does not detect steganography within files, it can be used to monitor data flows and connections to external hosts, which is critical for identifying channels where steganographically hidden data could be transmitted.

Data Encryption Standard (DES)is a cryptographic algorithm, not a forensic tool.

MP3Stegois a steganography tool for embedding data in MP3 files and is not designed for detection or monitoring.

Forensic Toolkit (FTK)is a forensic analysis software focused on acquiring and analyzing data from storage devices, not network monitoring.

The Communications Assistance to Law Enforcement Act (CALEA) mandates telecommunications carriers to assist law enforcement in executing authorized wiretaps, including on Voice over IP (VoIP) calls, ensuring lawful interception capabilities.

CALEA requires built-in surveillance capabilities in communications systems.

It balances privacy rights with law enforcement needs.

Comprehensive and Detailed Explanation From Exact Extract:

The foremost principle in digital forensics isnever altering the original evidence. This ensures integrity, authenticity, and admissibility in court.

Investigators analyze forensic copies, not originals.

Write-blockers and hashing are used to prevent changes.

Any alteration—intentional or accidental—can invalidate evidence.

Comprehensive and Detailed Explanation From Exact Extract:

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.
