Which of the following hives in the Windows Registry hierarchical database is volatile in nature and contains file-extension association information and programmatic identifier (ProgID), Class ID (CLSID), and Interface ID (IID) data?
正解：D
解説：
HKEY_CLASSES_ROOT (HKCR)is the Windows Registry location that storesfile-association and COM registration data, including mappings forfile extensions(e.g.,.docx) toProgIDs, and COM object identifiers such asCLSIDand interface-related identifiers likeIID. In forensic examinations, HKCR is frequently consulted to determine which application is registered to open a specific file type, to identify COM objects that may enable persistence or abuse (e.g., through COM hijacking), and to correlate suspicious registry-based execution mechanisms with installed software.
HKCR is often described asvolatile in naturebecause it is not a single standalone hive file stored independently in the same way as SAM or SYSTEM; instead, it is amerged, runtime viewcreated by the OS primarily fromHKLM\Software\Classes(machine-wide registrations) andHKCU\Software\Classes(per-user overrides). This means what you see under HKCR can vary depending on the current user context and system state, and the effective associations/registrations may change when software is installed, updated, or when per- user settings override machine defaults.
The other options represent different scopes: HKLM is system configuration, HKCU is user profile configuration, and HKCC reflects the current hardware profile-not the primary COM/file association repository.

Below are the various steps involved in forensic readiness planning.
Keep an incident response team ready to review the incident and preserve the evidence.
Create a process for documenting the procedure.
Identify the potential evidence required for an incident.
Determine the sources of evidence.
Establish a legal advisory board to guide the investigation process.
Identify if the incident requires full or formal investigation.
Establish a policy for securely handling and storing the collected evidence.
Define a policy that determines the pathway to legally extract electronic evidence with minimal disruption.
Identify the correct sequence of steps involved in forensic readiness planning.
正解：C
解説：
Forensic readiness planning focuses on ensuring an organization canlegally, efficiently, and reliablycollect usable digital evidence before an incident occurs. The planning sequence typically begins by definingwhat evidence would be neededto support likely incidents (3) and then mappingwhere that evidence residesacross systems, services, logs, endpoints, and network components (4). Once evidence needs and sources are known, readiness requires alegally compliant extraction pathwaythat minimizes business disruption and prevents evidence contamination (8). After defining extraction, an organization must formalizesecure handling and storage policies(chain of custody, access control, retention, integrity protection) so collected evidence remains admissible and trustworthy (7).
With those foundations in place, the organization can define decision criteria forwhen an event becomes a formal investigationand triggers deeper forensic procedures (6). A structureddocumentation processis then set so actions taken during acquisition and analysis are repeatable and defensible (2). Governance is reinforced by establishinglegal oversight/advisory supportto ensure compliance with jurisdictional requirements and internal policy (5). Finally, the plan is operationalized by ensuring anincident response team is preparedto preserve evidence promptly when incidents occur (1). Hence,3#4#8#7#6#2#5#1is the correct sequence.

Which of the following acts was passed by the U.S. Congress in 2002 to protect investors from the possibility of fraudulent accounting activities by corporations?
正解：B
解説：
TheSarbanes-Oxley Act (SOX)was enacted by the U.S. Congress in2002in response to major corporate accounting scandals and was specifically designed toprotect investorsby improving the accuracy, reliability, and integrity of corporate disclosures and financial reporting. SOX strengthens governance and accountability by requiring executive management (notably the CEO and CFO) to certify the correctness of financial statements and by mandating stronger internal controls over financial reporting. From a digital forensics and compliance perspective, SOX is closely tied to the need for reliableaudit trails, properrecords retention, and demonstrable control over systems that store or process financial data. Investigators frequently rely on SOX- driven logging, access controls, and change management records to determine who accessed financial systems, what changes were made, and whether those actions align with authorized procedures.
The other options do not match the question's purpose or jurisdiction: theElectronic Communications Privacy Actaddresses interception and access to electronic communications,GDPRis an EU data protection regulation (not a 2002 U.S. act focused on investor protection), and "Information Privacy Act 2014" is not the 2002 U.S.
corporate anti-fraud legislation. Therefore, the correct answer isSarbanes-Oxley Act (SOX) (C).

Harry, a security professional, was hired to identify the details of an attack that was initiated on a Windows system. In this process, Harry decided to check the logs of currently running applications and the information related to previously uninstalled or removed applications for suspicious events.
Which of the following folders in a Windows system stores information on applications run on the system?
正解：C
解説：
On Windows systems, thePrefetchfeature records execution-related artifacts to speed up subsequent program launches. When an executable is run, Windows often creates a.pf prefetch fileinC:\Windows\Prefetchthat contains valuable forensic indicators such as the executable name (mapped into the prefetch filename), last run time(s) (depending on Windows version), run count (in many versions), and a list of files and directories referenced during startup. Because these artifacts can persist even after an application is lateruninstalled or deleted, investigators commonly use the Prefetch directory to demonstrate that a program executed on a host and to help build timelines around suspicious activity. This is especially useful in intrusion investigations for identifying the execution of attacker tools, droppers, scripts launched via interpreters, or renamed binaries.
The other options are not standard repositories for program execution history.C:\Windows\debugmay contain specific debug logs for certain components but is not the canonical execution-tracking folder.C:
\Windows\BookandC:\subdirare not standard Windows forensic artifact locations. Therefore, the folder that stores information on applications run on the system isC:\Windows\Prefetch (C).
質問 # 70
While investigating a web attack on a Windows-based server, Jessy executed the following command on her system:
C:> net view <\10.10.10.11>
What was Jessy's objective in running the above command?
正解：A
解説：
The Windowsnet view \\<computer>command is used to enumerateshared resources(SMB shares) that a remote Windows system is publishing. When Jessy runsnet view \\10.10.10.11, her goal is to retrieve a list of the target host's visible shares-such as administrative shares (e.g.,C$,ADMIN$) and any custom shares created for departments, applications, or users. In forensic and incident-response practice, this is important because attackers commonly use SMB shares forlateral movement,staging tools,dropping payloads, andexfiltrating data. By reviewing the shares exposed by a suspected server, the investigator can quickly identify unexpected or overly permissive shares, locate potential repositories of web content or logs, and determine whether a compromised web server is also exposing file resources that expand the attacker's options.
The other options map to different commands and artifacts: disk space usage is checked with storage utilities (notnet view), open sessions are examined with commands likenet session, and identifying users accessing files typically involvesnet fileor server auditing logs. Therefore, Jessy's objective was toreview file shareson the remote host.
