質問 # 28
Which of the following help in estimating and totaling up the equivalent money value of the benefits and costs
to the community of projects for establishing whether they are worthwhile?
Each correct answer represents a complete solution. Choose all that apply.
正解：A、B
解説：
Explanation/Reference:
Explanation:
Cost-benefit analysis is a process by which business decisions are analyzed. It is used to estimate and total up
the equivalent money value of the benefits and costs to the community of projects for establishing whether they
are worthwhile. It is a term that refers both to:
helping to appraise, or assess, the case for a project, program, or policy proposal;
an approach to making economic decisions of any kind. Under both definitions, the process involves, whether
explicitly or implicitly, weighing the total expected costs against the total expected benefits of one or more
actions in order to choose the best or most profitable option. The formal process is often referred to as either
CBA (Cost-Benefit Analysis) or BCA (Benefit-Cost Analysis).
Answer option A is incorrect. Business Continuity Planning (BCP) is the creation and validation of a practiced
logistical plan that defines how an organization will recover and restore partially or completely interrupted
critical (urgent) functions within a predetermined time after a disaster or extended disruption. The logistical plan
is called a Business Continuity Plan.
Answer option C is incorrect. Disaster recovery is the process, policies, and procedures related to preparing for
recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced
disaster. Disaster recovery planning is a subset of a larger process known as business continuity planning and
should include planning for resumption of applications, data, hardware, communications (such as networking)
and other IT infrastructure. A business continuity plan (BCP) includes planning for non-IT related aspects such
as key personnel, facilities, crisis communication and reputation protection, and should refer to the disaster
recovery plan (DRP) for IT related infrastructure recovery / continuity.

You work as a Network Security Analyzer. You got a suspicious email while working on a forensic project. Now, you want to know the IP address of the sender so that you can analyze various information such as the actual location, domain information, operating system being used, contact information, etc. of the email sender with the help of various tools and resources. You also want to check whether this email is fake or real. You know that analysis of email headers is a good starting point in such cases. The email header of the suspicious email is given below:
What is the IP address of the sender of this email?
正解：A
解説：
The IP address of the sender of this email is 216.168.54.25. According to the scenario, you want to know the IP address of the sender so that you can analyze various information such as the actual location, domain information, operating system being used, contact information, etc. of the email sender with the help of various tools and resources. You also want to check whether this email is fake or real. You know that analysis of email headers is a good starting point in such cases. Once you start to analyze the email header, you get an entry entitled as X-Originating-IP. You know that in Yahoo, the X-Originating-IP is the IP address of the email sender and in this case, the required IP address is 216.168.54.25.
Answer options A, C, and B are incorrect. All these are the IP addresses of the Yahoo and Wetpaint servers.
質問 # 30
A network defender at a healthcare organization notices that several temporary user accounts created for interns during a previous project are still active although the interns left months ago.
These accounts have not logged in for over 90 days but retain access to shared folders on the internal network. The security team wants to take corrective action without deleting the accounts, in case they are needed again later for audit or reactivation purposes. What action should the network defender take to reduce the risk of unauthorized access?
正解：C
解説：
Disabling the accounts prevents them from being used to authenticate or access system resources while preserving the accounts for auditing or future reactivation. This action immediately eliminates the risk of unauthorized access from dormant accounts without permanently removing them from the system.

A large financial services firm has recently adopted machine learning-based analytics for threat hunting. Their hunting team now develops custom methods to correlate diverse cybersecurity datasets across the network and uses visualizations to track adversary movement. Most detection mechanisms are now automated, allowing the team to focus on optimizing threat detection models. They've fully integrated User and Entity Behavior Analytics (UEBA) and perform proactive scans and dark web monitoring. According to the Threat Hunting Maturity Model, which level best describes this organization's current capability?
正解：B
解説：
The highest maturity level in the Threat Hunting Maturity Model is characterized by advanced automation, machine learning-driven analytics, and the development of custom detection methodologies. At this level, organizations correlate multiple security datasets, use behavioral analytics such as UEBA, apply advanced visualizations to track adversary activity, and automate most detection processes. Analysts primarily focus on refining detection models and proactively discovering threats rather than performing manual investigations.
