質問 # 25
What is "root" in Linux?

正解：B

解説：
In the Linux operating system, "root" is the conventional name of the superuser who possesses the highest level of administrative control and access rights. Unlike standard user accounts, which are restricted to their own home directories and limited system actions, the root user has the authority to read, write, and execute any file on the system, regardless of the permissions set. This makes "root" the ultimate authority for system configuration, security management, and software installation.
Technically, the root user is identified by a User ID (UID) of 0. This account is essential for performing critical tasks such as managing user accounts, modifying the kernel, accessing protected hardware ports, and altering system-wide configuration files located in directories like /etc. In the context of ethical hacking and penetration testing, gaining "root access"-often referred to as "Privilege Escalation"-is frequently the ultimate goal. If an attacker gains root access, they have "full system compromise," meaning they can install backdoors, disable security logging, and pivot to other systems on the network.
Because of the immense power associated with this account, security controls dictate that it should be used sparingly. Most modern Linux distributions encourage the use of the sudo command, which allows a regular user to execute a specific task with root privileges temporarily. This minimizes the risk of accidental system damage or the permanent exposure of the root credentials. Protecting the root account is a fundamental master information security control; if the root password is weak or the account is left exposed via a remote service like SSH, the entire integrity of the information system is at risk. Understanding root is not just about identifying a user, but about understanding the hierarchy of permissions that governs all Linux-based security.


質問 # 26
What is Nmap?

正解：C

解説：
Nmap, also known asNetwork Mapper, is a widely used open-source tool in ethical hacking and penetration testing. It plays a critical role during thereconnaissance and scanning phasesof ethical hacking, where the primary goal is to collect information about target systems in a legal and authorized manner. Ethical hackers rely on Nmap to understand the structure and exposure of a network before moving forward with deeper security testing.
The tool works by sending various types of packets to target hosts and analyzing the responses. Based on these responses, Nmap can identifyactive hosts,open and closed ports,running services,service versions, operating systems, and even certainfirewall and intrusion detection configurations. This information is essential for identifying potential weaknesses such as unnecessary open ports, misconfigured services, or outdated software.
Option A correctly defines Nmap because it accurately reflects its purpose as a scanning and discovery tool rather than an exploitation utility. Option B is incorrect because Nmap does not exploit vulnerabilities; exploitation is typically performed using specialized frameworks such as vulnerability scanners or exploitation platforms. Option C is also incorrect because although Nmap can perform host discovery similar to ping, it offers far more advanced capabilities than simple network reachability checks.
From an ethical hacking perspective, Nmap supportspreventive and defensive security objectives. By revealing network visibility issues and configuration flaws, it enables organizations to harden systems, reduce attack surfaces, and comply with security best practices. When used ethically and with proper authorization, Nmap is a foundational tool for strengthening information security.


質問 # 27
What is a security breach?

正解：C

解説：
A security breach is acybersecurity incident in which unauthorized individuals gain access to sensitive personal or organizational data, making option A the correct answer. Security breaches can involve data theft, data exposure, system compromise, or loss of confidentiality, integrity, or availability.
Breaches may occur due to malware infections, phishing attacks, weak credentials, unpatched vulnerabilities, insider threats, or misconfigured systems. Ethical hackers analyze breach scenarios to understand how attackers bypass defenses and what impact the breach can have on business operations.
Option B is incorrect because hacking the entire internet is unrealistic and not a valid definition. Option C is incorrect because internet outages are infrastructure issues, not necessarily security breaches.
From a defensive standpoint, understanding security breaches helps organizations improve detection, response, and recovery capabilities. Ethical hackers help simulate breach scenarios to identify gaps in monitoring and incident response plans.
Preventing breaches requires layered security controls, user awareness, continuous monitoring, and regular testing. Ethical hacking plays a critical role in reducing breach likelihood and impact.


質問 # 28
Can the ssh protocol be breached?

正解：A

解説：
Secure Shell (SSH) is a cryptographic network protocol used for secure operating system logins and file transfers over insecure networks. While the protocol itself is built on strong encryption, it is not
"impenetrable". Like any technology, SSH can be breached if it is misconfigured or if the human elements managing it fail.
Attackers use several methods to breach SSH services:
* Brute Force and Dictionary Attacks: If an SSH server allows password authentication and the user has a weak password, an attacker can use automated tools to guess the credentials. This is the most common form of SSH breach.
* Key Theft: SSH often uses "Private Keys" for authentication. If an attacker gains access to a user's computer and steals an unencrypted private key, they can log into the server without a password.
* Exploiting Vulnerabilities: While rare, flaws can be found in specific implementations of the SSH server software (like OpenSSH). If the server is not regularly updated, an attacker might use a "zero- day" or known exploit to bypass authentication.
* Man-in-the-Middle (MITM): If a user ignores a "Host Key Verification" warning when connecting, an attacker could be intercepting their connection.
To harden SSH against these threats, ethical hackers recommend several controls: disabling root login, changing the default port (22) to a non-standard one to avoid automated bots, enforcing the use of SSH keys instead of passwords, and implementing "Fail2Ban" to lock out IP addresses that attempt too many failed logins. The security of SSH depends entirely on the rigor of its implementation.


質問 # 29
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.
