質問 # 55
What is risk assessment?
正解：A
解説：
Risk assessment is a systematic and critical component of information security management. It is the process of identifying, analyzing, and evaluating risks to determine their significance and to prioritize how they should be addressed. According to formal security standards, it involves comparing the findings of arisk analysis-which identifies threats and vulnerabilities-against establishedrisk assessment criteria. These criteria represent the organization's "risk appetite," or the level of risk they are willing to accept in exchange for pursuing their business objectives.
The risk assessment process typically involves three major steps:
* Identification: Finding out what could happen and why (e.g., identifying that a database is vulnerable to SQL injection).
* Analysis: Determining the likelihood of a threat occurring and the potential impact it would have on the organization's confidentiality, integrity, or availability.
* Evaluation: Deciding whether the resulting risk level isacceptable or tolerable.
If a risk is deemed intolerable, the organization must decide on a treatment strategy:Mitigation(reducing the risk via controls like firewalls),Transfer(buying insurance),Avoidance(stopping the risky activity), orAcceptance(acknowledging the risk if the cost of fixing it is too high). For an ethical hacker, a risk assessment provides the context for their work; it helps them understand which assets are most critical to the business and ensures that their findings are prioritized based on actual business impact rather than just technical severity.

What tool would you use to scan ports?
正解：B
解説：
Nmap is the primary tool used forport scanning, making option B the correct answer. Port scanning is a core activity during the reconnaissance and scanning phases of penetration testing, where the goal is to identify open, closed, or filtered ports on target systems.
Nmap allows ethical hackers to discover which services are running, their versions, and potential misconfigurations. It supports multiple scan types, including TCP SYN scans, UDP scans, and service detection scans, making it highly versatile and efficient.
Option A is incorrect because Metasploit is primarily an exploitation framework, not a dedicated port scanner.
Option C is incorrect because Shodan is an internet-wide search engine, not a direct scanning tool used against specific targets.
Understanding port scanning is essential for identifying attack surfaces. Open ports often expose services that may contain vulnerabilities or misconfigurations. Ethical hackers use Nmap responsibly to map networks and guide further testing.
From a defensive perspective, regular port scanning helps organizations identify unnecessary services and enforce least-exposure principles. Nmap remains one of the most fundamental tools in ethical hacking and network security.
質問 # 57
Do hackers only perform criminal acts?
正解：A
解説：
The term "hacker" is frequently misrepresented in popular media as being synonymous with "criminal." In the professional cybersecurity landscape, however, hacking is a skill set that can be applied for both malicious and constructive purposes. Ethical hackers, often referred to as "White Hat" hackers, use the same tools, techniques, and mindsets as malicious actors ("Black Hats"), but they do so with legal authorization and the intent to improve security. Their primary responsibility is to analyze systems, identify potential vulnerabilities, and report them to the stakeholders so they can be patched before a criminal can exploit them.
Ethical hacking is a structured discipline that follows specific phases: reconnaissance, scanning, gaining access, maintaining access, and clearing tracks-though the "clearing tracks" phase in an ethical context usually involves restoring the system to its original state and documenting the process. These professionals operate under a strict "Code of Ethics," ensuring they do no harm and maintain the confidentiality of the data they encounter. Many organizations employ ethical hackers through internal security teams or external penetration testing firms to conduct "Red Team" exercises, which simulate real-world attacks to test the organization's defensive capabilities.
Furthermore, the existence of "Bug Bounty" programs-where companies like Google, Microsoft, and Facebook pay independent researchers to find and report bugs-demonstrates that hacking is a recognized and valued profession. By reporting vulnerabilities instead of exploiting them for personal gain, ethical hackers play a vital role in the global digital economy. They help protect critical infrastructure, financial systems, and personal data. Therefore, while some hackers do engage in illegal activities, a significant portion of the hacking community is dedicated to the defensive side of cybersecurity, proving that the act of hacking itself is neutral; it is the intent and authorization that define its legality.
質問 # 58
Which of the following is an example of social engineering?
正解：B
解説：
Social engineering is an attack technique thatmanipulates human behaviorto gain unauthorized access to systems or information, making option A the correct answer. Asking users to disclose their passwords over the phone is a classic example of social engineering, often referred to as vishing (voice phishing).
Unlike technical attacks that exploit software vulnerabilities, social engineering targets human trust, fear, urgency, or lack of awareness. Attackers may impersonate IT staff, managers, or trusted vendors to convince victims to reveal credentials or perform harmful actions.
Option B is incorrect because antivirus software is a defensive security control, not an attack method. Option C is incorrect because updating the operating system is a security best practice that helps mitigate vulnerabilities.
From an ethical hacking standpoint, testing for social engineering vulnerabilities helps organizations understand their exposure tohuman-based attack vectors, which are among the most effective and commonly used by attackers. Ethical hackers may conduct controlled phishing simulations to assess employee awareness and response.
Mitigating social engineering attacks requires user training, security awareness programs, strong authentication methods, and clear verification procedures. Understanding social engineering is critical for building comprehensive defense strategies.
質問 # 59
What is a dictionary used for brute-force attacks?
正解：A
解説：
In ethical hacking and penetration testing, a dictionary used for brute-force or dictionary attacks is afile containing a list of potential passwordsthat an attacker or tester attempts against a target authentication mechanism. Therefore, option C is the correct answer.
Dictionary files are typically plain text documents that include commonly used passwords, leaked credentials, default passwords, variations of words, and patterns frequently chosen by users. Ethical hackers use these dictionaries duringpassword auditing and authentication testingto assess the strength of password policies implemented by an organization.
Option A is incorrect because a traditional language dictionary explains word meanings and is not structured for authentication testing. Option B is also incorrect because passwords are not normally stored in readable plain text documents; secure systems store passwords using hashing and salting mechanisms.
From a security perspective, dictionary attacks exploithuman behavior, particularly the tendency to choose weak or predictable passwords. Ethical hackers simulate these attacks in controlled environments to demonstrate the risks of poor password hygiene. The results help organizations enforce stronger password policies, multi-factor authentication, and account lockout mechanisms.
Understanding dictionary-based brute-force attacks is essential for managing attack vectors, as credential compromise remains one of the most common entry points for attackers. Ethical use of dictionaries allows organizations to proactively identify weaknesses before malicious actors exploit them.
