質問 # 87
What is Nessus used for?
正解：C
解説：
Nessus is a globally recognized, industry-standardvulnerability scannerused by security professionals to identify security flaws in a network, operating system, or application. Developed by Tenable, it is a comprehensive tool that automates the process of finding weaknesses such as unpatched software, weak passwords, misconfigurations, and "zero-day" vulnerabilities.
Nessus operates by probing a target system and comparing the results against an extensive, constantly updated database of thousands of known vulnerabilities (plugins). The scanning process typically involves:
* Host Discovery: Identifying which devices are active on the network.
* Port Scanning: Checking for open services and identifying their versions.
* Vulnerability Assessment: Running specific checks to see if those services are susceptible to known exploits.
* Compliance Auditing: Ensuring that systems meet specific security standards like PCI DSS or HIPAA.
Unlike "automated hacking" tools that focus on exploitation, Nessus is adiagnostic tool. It provides detailed reports that categorize vulnerabilities by severity (Critical, High, Medium, Low) and offers specific remediation advice on how to fix the issues. In a professional penetration test, Nessus is used during the
"Vulnerability Analysis" phase to provide a broad map of the target's weaknesses. This allows the tester to prioritize which flaws to attempt to exploit manually. Regular use of Nessus is a cornerstone of any proactive vulnerability management program.

What is privilege escalation?
正解：C
解説：
Privilege escalation is a critical phase in the cyber-attack lifecycle where an adversary seeks to expand their influence within a target environment after gaining an initial foothold. In standard security architectures, users are granted the "least privilege" necessary to perform their duties; however, attackers aim to bypass these restrictions to access sensitive data or execute restricted commands. This process is categorized into two distinct dimensions: horizontal and vertical escalation.
Horizontal privilege escalation(also known as lateral movement) occurs when an attacker gains access to resources belonging to another user with a similar level of permissions. This is often achieved through credential theft, session hijacking, or exploiting vulnerabilities in peer-level applications. While the attacker's authorization level remains the same, their reach increases as they assume different identities.
Vertical privilege escalation, or privilege elevation, is the process of moving from a standard user account to one with higher administrative or "root" privileges. This typically involves exploiting system bugs, misconfigurations, or unpatched vulnerabilities in the kernel or operating system. For instance, an attacker might use an exploit to trick a high-privileged service into executing malicious code on their behalf. Gaining root or administrator status is often the ultimate goal for an attacker, as it provides unrestricted control over the entire system, allowing for the deployment of malware, modification of security logs, and total data exfiltration. Effective defense against this threat involves implementing zero-trust architectures, rigorous patch management, and continuous monitoring for unauthorized permission changes.
質問 # 89
What is the best practice to protect against malware?
正解：C
解説：
The most effective and fundamental master information security control for protecting against malicious software is the installation and regular updating of antivirus software. Malware, which includes viruses, Trojans, and ransomware, is specifically designed to damage, infect, or steal data from a computer system without the owner's consent. Antivirus software serves as a critical defense layer by scanning files and monitoring system behavior to detect and neutralize these threats before they can execute their malicious payload.
However, simply having the software installed is insufficient; it must be kept up to date. Hackers and malware developers are constantly creating new "variants" of software designed to bypass existing security signatures.
Modern antivirus programs receive frequent updates containing the latest "definitions" or "signatures" of known malware, as well as heuristic analysis updates that help identify suspicious behavior from previously unknown threats.
Beyond antivirus, protecting against malware requires a multi-layered approach that includes administrative and technical controls. This involves the "periodic updating of the operating system" to patch vulnerabilities that malware might exploit to gain entry. It also requires "Security Awareness," where users are taught to avoid clicking on suspicious links or sharing credentials, as these are common infection vectors used in social engineering attacks. By combining automated technical defenses (antivirus) with proactive maintenance (patching) and user education, an organization can significantly mitigate the risk of a malware infection. This holistic strategy ensures that even if one control fails, other layers of defense are in place to safeguard the integrity and confidentiality of the organization's data.
質問 # 90
What tool would you use to scan ports?
正解：C
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 # 91
What is SQL Injection?
正解：A
解説：
SQL Injection is acritical web application vulnerabilitythat allows attackers to manipulate SQL queries executed by a database, making option A the correct answer. This vulnerability occurs when user input is improperly validated or sanitized before being included in SQL statements.
By exploiting SQL Injection, attackers can bypass authentication, retrieve sensitive data, modify or delete database contents, and in some cases execute administrative operations on the database server. Ethical hackers test for SQL Injection during web application penetration testing to identify insecure coding practices.
Option B is incorrect because SQL Injection is not a database system. Option C is incorrect because SQL Injection allows unauthorized users to execute SQL commands, not just administrators.
From a defensive security perspective, SQL Injection highlights the importance of secure coding practices such as parameterized queries, prepared statements, input validation, and least-privilege database access.
SQL Injection remains a top threat due to legacy applications and poor development practices. Ethical hackers use controlled testing to demonstrate the real-world impact of these vulnerabilities and help organizations protect critical data assets.
