質問 # 73
What is an XSS?
正解：C
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 # 74
What is the main purpose of a "SQL injection" attack?
正解：A
解説：
SQL Injection (SQLi) is one of the most prevalent and damaging information security threats targeting web applications. Its main purpose is to exploit a database by manipulating Structured Query Language (SQL) commands through user-supplied input. This occurs when an application fails to properly filter or "sanitize" data entered into forms, URL parameters, or cookies, allowing an attacker to "inject" their own SQL code into the query that the application sends to the back-end database.
When successful, a SQL injection attack can have catastrophic consequences for an organization's data integrity and confidentiality. An attacker can bypass authentication to log in as an administrator without a password, view sensitive user data, modify or delete database records, and in some cases, gain administrative control over the entire database server. A classic example is the ' OR 1=1 -- injection, which forces a query to return "true" regardless of the credentials provided, effectively opening the door to the system.
Managing the threat of SQLi is a top priority for web security. The most effective defense is the use of
"Parameterized Queries" (also known as prepared statements), which ensure that the database treats user input as data rather than executable code. Additionally, implementing "Input Validation" and the "Principle of Least Privilege" for database accounts helps mitigate the potential damage. From an ethical hacking standpoint, identifying SQLi vulnerabilities is a core component of vulnerability scanning and manual testing. Because databases often hold an organization's most valuable assets-including customer identities and financial records-protecting them from injection attacks is a non-negotiable aspect of modern information security management.
質問 # 75
As pentester can we exploit any vulnerability regardless of the affectations?
正解：B
解説：
The defining characteristic that separates a professional penetration tester from a criminal hacker islegal authorization and consent. In the pentesting process, it is strictly prohibited to exploit any vulnerability without the explicit, written consent of the system owner. Performing such acts without authorization-even if the intent is to "help"-is a criminal offense in most jurisdictions and can lead to severe legal consequences, including fines and imprisonment.
Before any testing begins, a "Rules of Engagement" (RoE) and a "Statement of Work" (SoW) must be signed.
These documents define the scope of the test: which systems can be touched, which exploits are allowed, and what hours the testing can take place. A pentester must also consider "affectations," meaning the potential impact on business operations. If exploiting a vulnerability has a high risk of crashing a production server or corrupting critical data, the tester must consult with the client before proceeding.
Ethical hacking is built on a foundation of trust and professional integrity. A pentester's goal is to improve security, not to disrupt business or act recklessly. If a critical vulnerability is found, the ethical response is to document it and inform the client immediately so it can be fixed. This disciplined approach ensures that the pentesting process remains a valuable security tool rather than a liability, reinforcing the fact that professional power in this field must always be balanced by strict adherence to legal and ethical standards.
質問 # 76
What is ZAP?
正解：B
解説：
The OWASP Zed Attack Proxy (ZAP) is one of the world's most popular free, open-source security tools for finding vulnerabilities in web applications. It is actively maintained by a global community of volunteers under the Open Web Application Security Project (OWASP). ZAP acts as a "man-in-the-middle proxy," meaning it sits between the tester's web browser and the web application being tested. This allows the tester to intercept, inspect, and even modify the requests and responses traveling between the two.
ZAP provides a wide array of functionalities essential for theWeb Application Pentestingprocess:
* Automated Scanner: It can automatically crawl a website to find vulnerabilities like SQL injection, Cross-Site Scripting (XSS), and insecure headers.
* Spidering: It maps out the structure of a website by following every link it finds.
* Fuzzing: It can send many variations of malicious input to a specific field to see if it can break the application or trigger an error.
* Active and Passive Scanning: It can passively watch traffic to find easy-to-spot issues or actively probe the server for deeper flaws.
For ethical hackers, ZAP is often compared to the commercial tool Burp Suite. While both perform similar tasks, ZAP's open-source nature and robust API make it a favorite for integrating into "DevSecOps" pipelines, where it can automatically test new code for vulnerabilities before it is deployed. Mastering ZAP is a core skill for any professional focused on securing the web-facing assets of an organization.
質問 # 77
What is active recognition?
正解：B
解説：
Active recognition, also known as "Active Reconnaissance," is a critical phase of penetration testing where the tester gathers detailed information by directly interacting with the target system or network. Unlike
"Passive Reconnaissance," which involves collecting publicly available information from search engines (like Google Dorking) or social media without the target's knowledge, active recognition involves sending data packets to the target's infrastructure to elicit a response.
Common activities during the active recognition phase include port scanning, service version detection, and vulnerability scanning. For example, using a tool like Nmap to scan a server's open ports is a form of active recognition. The scanner sends "probes" to the server, and based on the server's reply (or lack thereof), the tester can determine which services are running (e.g., a web server on port 80 or a database on port 3306).
This phase is essential because it provides the technical "blueprint" of the target that the tester will use to plan an exploit.
However, active recognition carries a significant risk: it is much more likely to be detected by security systems like Intrusion Detection Systems (IDS) or firewalls. Because the tester is directly "knocking on the doors" of the target, their IP address and activity may be logged. In a professional pentest, the degree of
"stealth" used during active recognition is a key consideration. Testers may slow down their scans or use techniques to blend in with normal network traffic to avoid detection. For the organization, being able to detect active reconnaissance is a vital part of threat management, as it often serves as the "early warning sign" that a more sophisticated attack is being prepared. Mastering this phase allows a pentester to efficiently map the attack surface while understanding the operational limits of the target's defensive controls.
