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. Parameter Tampering Attack
- B. SQL Injection Attack
- C. XSS Attack
- D. Directory Traversal Attack
正解：B
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.

Charline is working as an L2 SOC Analyst. One day, an L1 SOC Analyst escalated an incident to her for further investigation and confirmation. Charline, after a thorough investigation, confirmed the incident and assigned it with an initial priority.
What would be her next action according to the SOC workflow?
- A. She should communicate this incident to the media immediately
- B. She should immediately escalate this issue to the management
- C. She should formally raise a ticket and forward it to the IRT
- D. She should immediately contact the network administrator to solve the problem
正解：C
解説：
Once an L2 SOC Analyst like Charline confirms an incident, the SOC workflow dictates that the incident must be formally documented. This involves raising a ticket in the incident management system. The ticket should include all relevant details from the investigation, such as the nature of the incident, the affected systems, and the initial priority assigned. After raising the ticket, the L2 Analyst should forward it to the Incident Response Team (IRT). The IRT will then take over the incident to conduct a deeper analysis, perform containment measures, eradicate the threat, and recover systems to normal operation.

Which of the following Windows event is logged every time when a user tries to access the "Registry" key?
- A. 0
- B. 1
- C. 2
- D. 3
正解：D
解説：
The Windows event that is logged when a user tries to access a "Registry" key is identified by the event ID
4657. This event ID corresponds to the modification of a registry value. Here's how the process is tracked and logged:
* Detection: The system monitors access to registry keys and values.
* Logging: If a user accesses a registry key, and the key's audit policy is set to log such events, the event is logged.
* Event ID 4657: This specific event ID is used to denote that a registry value was modified, which includes creation, modification, and deletion of registry values.
* Audit Policy: For the event to be logged, "Set Value" auditing must be enabled in the registry key's System Access Control List (SACL).
References: The EC-Council SOC Analyst course materials and study guides detail the various Windows event IDs and their significance in monitoring and analyzing security events. Event ID 4657 is specifically covered as part of the curriculum that deals with registry access monitoring and logging1. Additionally, Microsoft's official documentation provides comprehensive information on this event ID and its role in security auditing2.

質問 # 51
According to the Risk Matrix table, what will be the risk level when the probability of an attack is very low and the impact of that attack is major?
- A. Extreme
- B. Low
- C. Medium
- D. High
正解：B
解説：
In a Risk Matrix, risk levels are determined by the intersection of the likelihood of an event occurring and the impact that event would have if it did occur. When the probability of an attack is very low, it means that the event is unlikely to happen. However, if the impact of that attack is major, it suggests that the event would have significant consequences if it did occur.
The combination of a very low probability with a major impact typically results in a low risk level. This is because the overall risk is mitigated by the low chance of the event happening, despite the potential for a significant impact. Therefore, even though the impact is major, the risk level is kept low due to the very low likelihood of occurrence.
References: The EC-Council's Certified SOC Analyst (CSA) program covers the concepts of risk assessment and the use of Risk Matrices. The CSA study materials and courses provide detailed explanations on how to evaluate and categorize risks based on their probability and impact, aligning with industry-standard practices123.
