質問 # 18
Which of the following tool can be used to filter web requests associated with the SQL Injection attack?
- A. Nmap
- B. Hydra
- C. ZAP proxy
- D. UrlScan
正解：D
解説：
UrlScan is a security tool that screens all incoming requests to a server and filters these requests based on rules set by the administrator. It is particularly effective against SQL Injection attacks because it can block requests that appear to be malicious, such as those containing SQL syntax or certain keywords often used in SQL Injection.
Nmap is a network scanning tool, not specifically designed for filtering web requests. ZAP Proxy is an open-source web application security scanner, which is used for finding vulnerabilities in web applications but not specifically for filtering requests. Hydra is a password cracking tool, which again, is not used for filtering web requests.
References: The answer is verified as per the EC-Council's SOC Analyst course materials and learning resources, which include training on various security tools and their purposes. Specifically, the EC-Council's SQL Injection Training and other related courses provide insights into the tools and techniques for defending against SQL Injection attacks123.

Banter, as a threat analyst, is engaged in this specific activity, which indicates that he is in the Processing and Exploitation stage. This stage is crucial as it prepares the data for further analysis and production of actionable intelligence.
References: The EC-Council's Certified Threat Intelligence Analyst (C|TIA) program outlines the threat intelligence life cycle and defines the Processing and Exploitation stage as the point where data is organized and prepared for analysis. This information is detailed in the EC-Council's official training and certification resources for the SOC Analyst role12.
質問 # 23
If the SIEM generates the following four alerts at the same time:
I.Firewall blocking traffic from getting into the network alerts
II.SQL injection attempt alerts
III.Data deletion attempt alerts
IV.Brute-force attempt alerts
Which alert should be given least priority as per effective alert triaging?
- A. III
- B. IV
- C. II
- D. I
正解：D
解説：
In the context of alert triaging within a Security Operations Center (SOC), the priority of alerts is typically determined based on the potential impact and urgency of the threat they represent.
* Firewall blocking traffic alerts indicate that the firewall is effectively doing its job by blocking unwanted traffic. While it's important to review these alerts to ensure legitimate traffic isn't being blocked, they generally represent a lower priority because the immediate threat has been mitigated by the firewall.
* SQL injection attempt alerts are of high priority because they indicate an active attempt to exploit a security vulnerability in order to manipulate or steal data.
* Data deletion attempt alerts also carry high priority as they could signify an attempt to remove or corrupt critical data, which could have significant impact on the availability and integrity of data.
* Brute-force attempt alerts are important as they may indicate an ongoing attempt to gain unauthorized access to systems. However, if the attempts are being blocked, these alerts may be of a slightly lower priority compared to an active exploit attempt like SQL injection.
Given these considerations, the alert for the firewall blocking traffic would generally be given the least priority, as it indicates a threat that has already been contained.
References: The EC-Council's Certified SOC Analyst (CSA) program covers the fundamentals of SOC operations, including the management of alerts and the triaging process. The program emphasizes the importance of prioritizing alerts based on the severity and potential impact of the threat12. For more detailed information, the EC-Council's official CSA study guides and courses should be consulted. These resources provide in-depth knowledge on how to effectively manage and prioritize alerts in a SOC environment.

Identify the password cracking attempt involving a precomputed dictionary of plaintext passwords and their corresponding hash values to crack the password.
- A. Bruteforce Attack
- B. Dictionary Attack
- C. Syllable Attack
- D. Rainbow Table Attack
正解：D
解説：
A Rainbow Table Attack involves using a precomputed table of hash values for every possible combination of characters for a given password policy. This table, known as a rainbow table, is then used to look up the corresponding plaintext password for a given hash value. The process involves the following steps:
* Precomputation: Generate the rainbow table by computing hash values for all possible password combinations according to the password policy.
* Storage: Store these precomputed hash values in a table, associating each with its plaintext password.
* Lookup: When a hash value is obtained during a password cracking attempt, search the rainbow table for the corresponding plaintext password.
* Match: If a match is found, the plaintext password associated with the hash value is the cracked password.
Rainbow tables are effective because they trade storage space for time, allowing for quicker password cracking compared to brute-force or dictionary attacks, which compute hash values on the fly.
References: The EC-Council's materials on password cracking techniques discuss various methods including dictionary attacks, brute-force attacks, and rainbow table attacks. Specifically, the EC-Council Learning Paths and Skill Packs provide detailed insights into these techniques, emphasizing the use of rainbow tables as a method of cracking passwords by comparing precomputed hash values to those obtained from a system12. Additionally, EC-Council's CyberQ platform offers practical exercises related to password cracking, including the use of rainbow tables2.

質問 # 28
Sam, a security analyst with INFOSOL INC., while monitoring and analyzing IIS logs, detected an event matching regex /\\w*((\%27)|(\'))((\%6F)|o|(\%4F))((\%72)|r|(\%52))/ix.
What does this event log indicate?
- A. SQL Injection Attack
- B. Parameter Tampering Attack
- C. XSS Attack
- D. Directory Traversal Attack
正解：A
解説：
The regex pattern /\\w*((\%27)|(\'))((\%6F)|o|(\%4F))((\%72)|r|(\%52))/ix is designed to detect SQL injection attacks. The pattern looks for common SQL injection payloads which typically include an apostrophe or single quote character (' or %27 when URL-encoded) followed by a logical operator OR (represented by o, %6F, O, %4F, r, %72, R, %52). SQL injection attacks involve inserting or "injecting" a SQL query via the input data from the client to the application. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system, and in some cases, issue commands to the operating system.
References: The explanation provided is based on standard practices of monitoring and analyzing IIS logs for security threats. Information about the regex pattern used for detecting SQL injection attacks can be found in various cybersecurity resources, including OWASP's guide on Testing for SQL Injection1 and Microsoft's documentation on IIS logging2. These resources explain how regex patterns are used to identify potential security threats in log files and the importance of monitoring logs for unusual patterns that may indicate an attack.

質問 # 31
Identify the attack when an attacker by several trial and error can read the contents of a password file present in the restricted etc folder just by manipulating the URL in the browser as shown:
http://www.terabytes.com/process.php./../../../../etc/passwd
- A. SQL Injection Attack
- B. Denial-of-Service Attack
- C. Form Tampering Attack
- D. Directory Traversal Attack
正解：D
解説：
The attack described is a Directory Traversal Attack. This type of attack occurs when an attacker exploits vulnerabilities in a web application (or a web server's software) to gain unauthorized access to files and directories that are stored outside of the web root folder. By manipulating variables that reference files with ../ sequences (also known as dot-dot-slash), the attacker can move up the directory hierarchy and access files or directories that should be restricted. This can lead to information disclosure, such as reading sensitive files like /etc/passwd, which contains user password details in Unix-based systems.
In the given URL http://www.terabytes.com/process.php./../../../../etc/passwd, the attacker uses the ../ pattern to navigate up from the current directory where process.php resides, aiming to reach the root directory and then descend into the /etc/ directory to access the passwd file. This is a classic example of a Directory Traversal Attack.
References: The EC-Council's Certified SOC Analyst course covers various types of cyber attacks, including Directory Traversal Attacks. Specific references to this type of attack can be found in the EC-Council's official training materials for the Certified SOC Analyst (CSA) program, such as the CSA study guide and related courses that discuss web application vulnerabilities and attacks123.
