EC-COUNCIL EC-Council Digital Forensics Essentials (DFE) 認定 112-57 試験問題 (Q61-Q66):

質問 # 61
James, a forensic specialist, was appointed to investigate an incident in an organization. As part of the investigation, James is attempting to identify whether any external storage devices are connected to the internal systems. For this purpose, he employed a utility to capture the list of all devices connected to the local machine and removed suspicious devices.
Identify the tool employed by James in the above scenario.

正解：A


質問 # 62
Philip, a forensic officer, was tasked with investigating a crime scene. In this process, he created bit-by-bit copies of the suspect drive and retrieved all the disk images using the dd command.
Which of the following data acquisition image formats is extracted by Philip in the above scenario?

正解：C

解説：
The UNIX/Linuxddutility performs abit-by-bit (sector-by-sector) copyfrom an input device (such as a physical disk) to an output target (another device or a flat file). In digital forensics guidance, this type of output is known as araw (bitstream) imagebecause it captures the exact sequence of bytes from the source media without embedding structured case metadata, compression, or container features by default. The resulting file is often referred to as a "dd image" and may use extensions like.ddor.img, but the key point is theformat is raw: it represents a straightforward byte-for-byte representation of the original storage, including allocated data, unallocated space, slack space, and file system structures.
By contrast,AFFandAFF4are forensic container formats designed to store evidence data along with metadata (and often support features such as chunking, compression, and richer integrity structures). "Proprietary format" refers to vendor-specific containers (for example, formats created by certain commercial forensic tools) rather than the generic output produced by dd. Since Philip specifically usedddto create bit-by-bit disk images, the extracted acquisition image format isRaw Format (A).


質問 # 63
An organization decided to strengthen the security of its network by studying and analyzing the behavior of attackers. For this purpose, Steven, a security analyst, was instructed to deploy a device to bait attackers.
Steven selected a solution that appears to contain very useful information to lure attackers and find their locations and techniques.
Identify the type of device deployed by Steven in the above scenario.

正解：A

解説：
Ahoneypotis a deliberately deployed decoy system or service designed toattract attackersby appearing valuable or vulnerable, thereby enabling defenders to observe malicious behavior in a controlled manner.
Digital forensics and incident response references describe honeypots as tools forthreat intelligence and evidence collection, because they can record interaction details such as connection sources, exploited services, commands executed, malware dropped, and attempted privilege escalation. This directly matches the scenario: Steven deployed something that "appears to contain very useful information" tolure attackersand help identify theirlocations and techniques. Honeypots are typically instrumented with extensive logging and monitoring, making them especially useful for building timelines, extracting indicators of compromise, and understanding adversary tactics, techniques, and procedures.
The other options do not align with the "bait attackers" goal. AnIDSprimarily detects and alerts on suspicious activity but is not intended to impersonate a valuable target. Afirewallenforces access control rules to block
/allow traffic, not entice attackers. Arouterforwards packets and provides network connectivity; it is not a deception platform. Therefore, the device type described is aHoneypot (C).


質問 # 64
Bob, a security specialist at an organization, extracted the following IIS log from a Windows-based server:
"2019-12-12
06:11:41 192.168.0.10 GET /images/content/bg_body1.jpg - 80 - 192.168.0.27 Mozilla/5.0+(Windows+NT+6.
3;+WOW64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/48.0.2564.103+Safari/537.36
http://www.moviescope.com/css/style.css 200 0 0 365"
Identify the element in the above IIS log entry that indicates the request was fulfilled without error.

正解：A

解説：
In Microsoft IIS (W3C Extended) logging, each request line records multiple standardized fields that help investigators reconstruct what was accessed, by whom, and with what outcome. Among these fields, the most direct indicator of whether the server successfully handled the request is theHTTP status codecaptured in thesc-statusfield. A status code of200means"OK", indicating the server located the requested resource (here,
/images/content/bg_body1.jpg) and returned it successfully to the client without application-level failure.
Other numbers in the entry represent different attributes:80is the server port used for the HTTP request,
192values appear as part of IP addressing (client/server addresses), and537is embedded in the user-agent string (AppleWebKit build number), not a success indicator. IIS often logs additional substatus and Win32 status values (e.g.,sc-substatusandsc-win32-status) to refine the outcome; in the shown line, those follow the
200 as "200 0 0 ...", reinforcing that no substatus error or OS-level error occurred. Therefore,200is the element confirming the request was fulfilled without error.


質問 # 65
Which of the following techniques is defined as the art of hiding data "behind" other data without the target's knowledge, thereby hiding the existence of the message itself?

正解：A

解説：
Steganographyis the technique of concealing a messagewithin another seemingly harmless carrier(such as an image, audio file, video, or document) so that theexistence of the hidden message is not apparentto an observer. Digital forensics references distinguish steganography from encryption: encryption scrambles content but usually leaves visible indicators that protected data exists (ciphertext), while steganography aims to make the communication look ordinary, reducing suspicion. In practice, steganographic methods often embed data into redundant or less perceptible parts of the carrier, such as modifying least significant bits in pixel values, altering frequency components in audio, or inserting data into metadata or unused file structures.
The other options do not match the definition.Password crackingis an access technique to recover authentication secrets, not a concealment method.Artifact wipingis an anti-forensics method intended to remove traces (logs, files, slack space remnants), but it does not "hide behind" other data-it destroys or overwrites evidence.Program packerscompress/obfuscate executables to hinder static analysis and detection, but they still produce an executable whose presence is evident; they do not primarily hide messages inside benign files. Therefore, the described "hiding the existence of the message itself" corresponds toSteganography (C).
