NEW QUESTION # 49
John as a SOC analyst is worried about the amount of Tor traffic hitting the network. He wants to prepare a dashboard in the SIEM to get a graph to identify the locations from where the TOR traffic is coming.
Which of the following data source will he use to prepare the dashboard?
Answer: C
Explanation:
To monitor and visualize Tor traffic hitting the network, John would need data sources that can provide detailed information about the source IP addresses of incoming traffic, as well as the capability to resolve these IP addresses to more identifiable information such as hostnames or geographical locations. DHCP logs, or other log sources capable of maintaining detailed IP address records and facilitating IP-to-Name resolution, would be suitable for this purpose. This data would allow John to create a dashboard in the SIEM system that maps the source IP addresses of Tor traffic to their corresponding locations or identities, providing insights into where the Tor traffic is originating. While web server logs (options B, C, and D) can provide IP addresses, they might not offer the same level of detail or resolution capabilities as DHCP logs or similar network-level logs for this specific use case.

NEW QUESTION # 50
Identify the event severity level in Windows logs for the events that are not necessarily significant, but may indicate a possible future problem.
Answer: B
Explanation:
In the context of Windows logs, the event severity level that indicates events that are not necessarily significant but may point to a possible future problem is classified as a "Warning." This level is used to log events that are not immediately harmful, such as an impending disk space shortage or other conditions that could potentially cause problems if not addressed.
References: The EC-Council's Certified SOC Analyst (CSA) program covers the fundamentals of SOC operations, including log management and correlation, which would encompass understanding the severity levels of events in Windows logs1. Additionally, the discussion on the ExamTopics website corroborates that the answer to this question is "Warning"2. Further general information on Windows event logging can be found in resources like Sumo Logic's guide to Windows Event Logging3 and other incident response guides that discuss the importance of monitoring event severity levels within a SOC4.

NEW QUESTION # 51
Which of the following event detection techniques uses User and Entity Behavior Analytics (UEBA)?
Answer: B
Explanation:
User and Entity Behavior Analytics (UEBA) is a cybersecurity process that uses machine learning, algorithms, and statistical analyses to detect abnormal behavior of users and entities within an organization.
UEBA systems analyze patterns of behavior and can identify anomalies that deviate from the norm, which could indicate a potential security threat.
Anomaly-based detection is the technique that aligns with UEBA's functionality. It contrasts with:
* Rule-based detection, which relies on predefined rules to detect threats.
* Heuristic-based detection, which uses experience-based techniques.
* Signature-based detection, which depends on known patterns orsignatures of malware to identify threats.
Anomaly-based detection systems are designed to be dynamic, continuously learning and establishing what is considered normal to identify deviations. This approach is particularly effective in identifying previously unknown threats, hence its alignment with UEBA.
References: The EC-Council's Certified SOC Analyst (CSA) program covers the fundamentals of SOC operations, including incident detection with Security Information and Event Management (SIEM) and enhanced incident detection with Threat Intelligence, which encompasses the use of UEBA for anomaly detection123.
NEW QUESTION # 52
A healthcare organization's SIEM detects unusual HTTP requests targeting its patient portal. The requests originate from a foreign IP address and occur during non-business hours. The methods used are primarily TRACE and OPTIONS, which are rarely seen in normal web traffic. The SIEM correlates these with increased reconnaissance activity on other servers within the same subnet. What is the primary security concern with TRACE and OPTIONS requests?
Answer: A
Explanation:
TRACE and OPTIONS are often associated with reconnaissance because they can reveal how a server is configured and what capabilities it supports. OPTIONS can disclose which HTTP methods are allowed (GET, POST, PUT, DELETE, etc.), helping attackers identify whether risky methods are enabled or misconfigured.
TRACE can be abused to reflect request headers back to the client, which may expose sensitive header information in certain misconfigurations and historically has been associated with cross-site tracing risks. In SOC investigations, unusual usage of TRACE/OPTIONS-especially from foreign IPs and outside business hours-often indicates probing to map the attack surface before selecting an exploit path. Uploading payloads is more associated with PUT/POST to vulnerable endpoints, not primarily TRACE/OPTIONS. DDoS facilitation is not a primary characteristic of these methods. Authentication bypass is not an inherent feature of TRACE/OPTIONS; attackers still need a separate vulnerability to bypass auth. Because the question asks for the primary concern, the best answer is that these methods can reveal supported methods and header behavior, increasing attacker knowledge and enabling follow-on exploitation attempts.
NEW QUESTION # 53
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?
Answer: D
Explanation:
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.
