質問 # 706
Leverox Solutions hired Arnold, a security professional, for the threat intelligence process. Arnold collected information about specific threats against the organization. From this information, he retrieved contextual information about security events and incidents that helped him disclose potential risks and gain insight into attacker methodologies. He collected the information from sources such as humans, social media, and chat rooms as well as from events that resulted in cyberattacks. In this process, he also prepared a report that includes identified malicious activities, recommended courses of action, and warnings for emerging attacks.
What is the type of threat intelligence collected by Arnold in the above scenario?
正解：C
解説：
Operational Threat Intelligence provides insights into specific attacker methodologies, motivations, and campaigns. It involves gathering contextual information from real-world attacks, open-source intelligence (OSINT), social media, dark web forums, chat rooms, and human intelligence (HUMINT).
As per CEH v13 Official Courseware:
Operational intelligence is primarily used by security teams to anticipate specific incoming attacks.
It helps provide actionable information such as:
Who is attacking?
Why are they attacking?
What methods are they using?
What infrastructure is involved?
Incorrect Options:
A). Strategic Threat Intelligence is high-level, focusing on long-term trends and business risks.
B). Tactical Threat Intelligence is focused on TTPs (Tactics, Techniques, and Procedures) of known threats, primarily for defenders and analysts.
D). Technical Threat Intelligence includes IoCs like IPs, hashes, and URLs, often short-lived and used for detection systems.

質問 # 707
During a red team assessment at a banking client in Chicago, ethical hacker David gains access to the internal LAN. He sets up a test machine and injects crafted messages into the network.
Soon, all traffic between a finance workstation and the authentication server is silently routed through his system without changing switch configurations. He observes usernames and passwords passing through his interface, even though no proxy or VPN is in use. Which sniffing technique did David most likely use?
正解：A
解説：
Injecting crafted messages to redirect traffic through the attacker's machine, allowing capture of credentials without modifying switch configurations, indicates ARP spoofing, which poisons the ARP cache to intercept LAN traffic.
質問 # 708
In the crisp winter dawn of Oslo, Norway, certified ethical hacker Lars Hagen was performing an authorized penetration test for Apex Benefits, a government benefits-management platform. While testing the claim- reference search field, he submitted progressively longer strings consisting of random and meaningless characters to observe how the application handled excessive input.
The application accepted the input but began exhibiting abnormal behavior as the input length increased, including inconsistent responses and unexpected output patterns not seen during normal use. By systematically extending the length of these inputs, Lars consistently reproduced the anomalous behavior, indicating problems in how the backend processed oversized data.
How is SQL-injection black-box penetration testing being applied in this scenario?
正解：A
解説：
The tester is detecting truncation issues. In CEH-oriented SQL-injection black-box testing, progressively longer junk strings are supplied to determine whether an application, database field, or variable cuts off input at an unexpected boundary. Truncation can remove closing characters, delimiters, escaping data, or portions of a dynamically constructed SQL statement. The resulting malformed query may produce errors, inconsistent results, or exploitable changes in query structure. Option B therefore matches both the input pattern and the observed behavior.
Basic SQL-injection detection normally begins with SQL-sensitive characters or logical conditions, such as quotation marks or Boolean expressions. Input-sanitization testing examines whether special characters are encoded, removed, or safely rejected. Detecting SQL modification involves deliberately supplying input intended to change a query's logic. The scenario instead emphasizes the increasing length of otherwise meaningless data.
This distinction matters because the video visibly selected "Detecting Input Sanitization," but that selection does not match the stated test. Input sanitization concerns the treatment of dangerous content, whereas truncation testing concerns maximum length and the consequences of cutting data short. The corrected answer is B. Secure remediation includes strict server-side length validation, parameterized queries, consistent data- type limits, and safe handling of overlength input before it reaches SQL construction.
質問 # 709
By using a smart card and pin, you are using a two-factor authentication that satisfies
正解：A
解説：
Two-factor Authentication or 2FA is a user identity verification method, where two of the three possible authentication factors are combined to grant access to a website or application.1) something the user knows,
2) something the user has, or 3) something the user is.
The possible factors of authentication are:
Something the User Knows:
This is often a password, passphrase, PIN, or secret question. To satisfy this authentication challenge, the user must provide information that matches the answers previously provided to the organization by that user, such as "Name the town in which you were born."
Something the User Has:
This involves entering a one-time password generated by a hardware authenticator. Users carry around an authentication device that will generate a one-time password on command. Users then authenticate by providing this code to the organization. Today, many organizations offer software authenticators that can be installed on the user's mobile device.
Something the User Is:
This third authentication factor requires the user to authenticate using biometric data. This can include fingerprint scans, facial scans, behavioral biometrics, and more.
For example: In internet security, the most used factors of authentication are:
something the user has (e.g., a bank card) and something the user knows (e.g., a PIN code). This is two- factor authentication. Two-factor authentication is also sometimes referred to as strong authentication, Two- Step Verification, or 2FA.
The key difference between Multi-Factor Authentication (MFA) and Two-Factor Authentication (2FA) is that, as the term implies, Two-Factor Authentication utilizes a combination of two out of three possible authentication factors. In contrast, Multi-Factor Authentication could utilize two or more of these authentication factors.
質問 # 710
What information security law or standard aims at protecting stakeholders and the general public from accounting errors and fraudulent activities within organizations?
正解：C
解説：
SOX stands for Sarbanes-Oxley Act of 2002. It is a U.S. federal law enacted to protect shareholders and the general public from accounting errors and corporate fraud.
Key points:
Requires strict internal controls and financial disclosures in publicly traded companies.
Mandates regular audits and IT security controls related to financial data.
Applies especially to accounting systems, databases, access controls, and IT procedures related to financial reporting.
Incorrect Options:
A). PCI-DSS relates to securing credit card data.
B). FISMA pertains to federal agency cybersecurity standards.
D). ISO/IEC 27001:2013 is an international information security standard, not a legal requirement for financial integrity.
