質問 # 23
What is a vulnerability scan?
正解：B
解説：
Vulnerability scanning is a fundamental, automated cybersecurity practice designed to systematically identify and evaluate security weaknesses within an organization's IT infrastructure. Unlike penetration testing, which actively attempts to exploit flaws to gauge the depth of a potential breach, vulnerability scanning is generally a non-intrusive "reconnaissance-level" check. It uses specialized software tools-vulnerability scanners-to probe network devices, servers, and applications to compare discovered services against databases of known security flaws (Common Vulnerabilities and Exposures, or CVEs).
The process typically unfolds in several stages:
* System Discovery: Identifying all physical and virtual assets on the network, such as routers, physical hosts, and cloud endpoints.
* Vulnerability Detection: Probing open ports and services using techniques like "banner grabbing" or
"fingerprinting" to identify software versions and configurations.
* Prioritization and Reporting: Assigning severity scores (often using the CVSS framework) to identified flaws based on factors like ease of exploitation and potential impact.
Vulnerability scans are essential for maintaining a strong security posture because they can be run continuously and automatically at a lower cost than manual testing. They help organizations stay ahead of
"zero-day" and emerging threats by flagging missing patches, weak passwords, and insecure default configurations. While highly effective at identifying broad classes of vulnerabilities-such as SQL injection or outdated encryption-scanners can produce "false positives," requiring security teams to validate findings before proceeding with remediation. Ultimately, vulnerability scanning serves as the critical first step in a broader vulnerability management lifecycle.
質問 # 24
What is a remote exploit?
正解：B
解説：
A remote exploit is a sophisticated attack vector where a threat actor manipulates a vulnerability in a system over a network-typically the internet-without having prior physical or local access to the target machine.
This type of exploit is highly dangerous because the attacker can be located anywhere in the world, making it difficult to trace or physically stop. Remote exploits usually target services that are "listening" for incoming connections, such as web servers (HTTP/HTTPS), database servers (SQL), or remote desktop protocols (RDP).
The mechanism of a remote exploit often involves sending specially crafted data packets to a service to trigger a specific flaw, such as a buffer overflow or an injection vulnerability. If successful, the exploit can allow the attacker to execute arbitrary code with the same privileges as the service being attacked. This is often the first step in a larger attack chain, where the remote exploit provides the "initial access" needed to drop malware or pivot further into the internal network.
To manage and mitigate the risks associated with remote exploits, organizations must focus on "Attack Surface Reduction." This involves closing unnecessary ports, implementing robust firewalls, and using Intrusion Detection Systems (IDS) to flag suspicious network traffic. Patch management is the most effective defense, as most remote exploits target known vulnerabilities that have available security updates. Ethical hackers use remote exploits during penetration tests to demonstrate the exposure of an organization's perimeter. By identifying these external-facing weaknesses, they help the organization prioritize defenses on the services most likely to be targeted by global threat actors.
質問 # 25
What is ethical responsibility in hacking?
正解：B
解説：
Ethical responsibility in hacking refers to the obligation to perform all security testing activitieslegally, transparently, and with explicit authorization, making option B the correct answer. Ethical hacking is not defined solely by technical skill, but by adherence to legal boundaries, professional conduct, and organizational policies.
Ethical hackers must always obtainwritten permissionbefore conducting reconnaissance, scanning, or exploitation activities. This authorization clearly defines the scope, targets, and limitations of the engagement.
Without permission, even basic scanning activities may be considered illegal or unethical, regardless of intent.
Option A is incorrect because technical knowledge alone does not make hacking ethical. Skills must be applied responsibly. Option C is incorrect because performing scans without permission is a violation of ethical and legal standards and may result in criminal charges.
From an ethical hacking perspective, responsibility also includes responsible disclosure, minimizing impact, protecting sensitive data, and reporting findings accurately. Ethical hackers must avoid data misuse, service disruption, or unnecessary system damage.
Understanding ethical responsibility is foundational to professional cybersecurity practice. It distinguishes ethical hackers from malicious actors and ensures that security testing contributes positively to risk reduction, compliance, and organizational trust.
質問 # 26
What tool would you use to scan ports?
正解：A
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 # 27
Which of the following is an example of social engineering?
正解：B
解説：
Identifying examples of social engineering is crucial for recognizing the diverse ways attackers attempt to circumvent technical security controls. A classic and highly effective example of social engineering is
"vishing" (voice phishing), where an attacker calls a user and attempts to persuade them to disclose sensitive information, such as their network password, over the phone. This technique relies on the attacker's ability to sound professional, authoritative, or helpful, creating a scenario where the victim feels compelled to comply.
In contrast, options such as the use of antivirus software and periodic updating of the operating system are technical security controls. These are automated or administrative processes designed to protect the system's integrity from malware and exploits. Social engineering, however, bypasses these technical defenses by targeting the user directly. When an attacker asks for a password over the phone, they are not attempting to
"break" the password through a brute-force attack; they are simply asking for the "key to the front door" by exploiting the user's trust.
This specific example highlights the concept of "Pretexting." The attacker may claim there is a critical security breach or a technical error on the user's account and that the password is required to "fix" the issue.
Once the user discloses the password, the attacker has gained legitimate access to the system, often leaving no immediate trace of a technical intrusion. For an ethical hacker, documenting these types of vulnerabilities is essential. It demonstrates that even the most advanced firewall or antivirus cannot protect an organization if its employees are willing to give away credentials to an unverified caller. This reinforces the need for
"Security Awareness Training," which teaches individuals that legitimate IT personnel will never ask for a full password over a phone call or through an unencrypted communication channel.
