質問 # 98
Do hackers only perform criminal acts?
正解：B
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 # 99
What is an XSS?
正解：B
解説：
Cross-Site Scripting (XSS) is a critical security vulnerability prevalent in web applications. It occurs when an application includes untrusted data in a web page without proper validation or escaping, allowing an attacker to inject and execute malicious scripts-typically JavaScript-in the victim's web browser. Because the browser trusts the script as if it originated from the legitimate website, the script can access sensitive information stored in the browser, such as session cookies, tokens, or personal data.
There are three primary types of XSS:
* Stored (Persistent) XSS: The malicious script is permanently stored on the target server (e.g., in a database, in a comment field). When a victim views the page, the script executes.
* Reflected XSS: The script is "reflected" off a web application to the victim's browser, usually through a link containing the payload (e.g., in a URL parameter).
* DOM-based XSS: The vulnerability exists in the client-side code rather than the server-side code, where the script is executed by modifying the Document Object Model (DOM) environment.
Managing the threat of XSS involves implementing strict input validation and output encoding. Developers must ensure that any data provided by users is treated as "untrusted" and filtered to remove executable code before it is rendered on a page. From an ethical hacking perspective, identifying XSS is a key part of web application penetration testing. A successful XSS attack can lead to account hijacking, website defacement, or the redirection of users to malicious websites. By understanding how malicious scripts are executed in the context of other users' browsers, security professionals can better protect the integrity of web services and the privacy of their users.
質問 # 100
Which of the following is a network security protocol designed to authenticate and authorize remote users to securely access network resources?
正解：B
解説：
Secure Shell (SSH) is a robust cryptographic network protocol utilized for operating network services securely over an unsecured network. Its primary application is the secure remote login to computer systems by administrators and users. Unlike earlier protocols such as Telnet or rlogin, which transmitted data (including passwords) in plain text, SSH provides a secure, encrypted channel. It achieves this through a suite of cryptographic techniques that ensure theconfidentiality,integrity, andauthenticityof the data being transmitted between the client and the server.
The protocol operates using a client-server architecture, where an SSH client initiates a connection to an SSH server. SSH facilitates both authentication and authorization. Authentication is typically performed using either a password or, more securely, a public-private key pair. Once the user's identity is verified, the protocol authorizes the level of access based on the server's configuration. Beyond simple terminal access, SSH supports secure file transfers (SFTP) and port forwarding, allowing other network protocols to be "tunneled" through its encrypted connection. From a security standpoint, while SSH is highly secure, it can be breached if misconfigured-such as by allowing weak passwords or failing to disable root login. Consequently, ethical hackers prioritize hardening SSH services as a fundamental control in protecting organizational assets.
質問 # 101
What is an exploit in the hacking world?
正解：C
解説：
In ethical hacking and cybersecurity, an exploit iscode or a sequence of commands designed to take advantage of a specific vulnerabilityin a system, application, or service. Therefore, option A is the correct answer.
Exploits are typically used after vulnerabilities have been identified during reconnaissance and scanning phases. They allow attackers or ethical hackers to verify whether a weakness can be practically abused.
Exploits may result in unauthorized access, data disclosure, privilege escalation, or remote code execution, depending on the nature of the vulnerability.
Option B is incorrect because malware removal is a defensive activity and does not involve exploitation.
Option C is incorrect because malicious programs that spread via social networks are classified as malware, not exploits.
From an ethical hacking perspective, exploits are used incontrolled and authorized environmentsto demonstrate the real-world impact of vulnerabilities. Ethical hackers often use exploit frameworks to safely test systems and provide remediation guidance.
Understanding exploits helps organizations prioritize patching, improve system hardening, and reduce exposure to known attack techniques. Ethical use of exploits strengthens security rather than undermines it.
質問 # 102
What is a vulnerability scan?
正解：C
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.
