NEW QUESTION # 121
Identify the type of attack, an attacker is attempting on www.example.com website.
- A. Session Attack
- B. Cross-site Scripting Attack
- C. SQL Injection Attack
- D. Denial-of-Service Attack
Answer: B
Explanation:
The scenario depicted suggests an attacker is injecting a script into the URL of the website
"www.example.com" which triggers an alert message. This behavior is characteristic of a Cross-site Scripting (XSS) attack. In XSS attacks, attackers exploit vulnerabilities in web applications to inject malicious scripts into web pages viewed by other users. The injected scripts can steal user data, deface web pages, or redirect users to malicious sites.
The specific attack vector here involves the attacker adding a script to the URL that causes the website to display an alert message. This indicates that the website is not properly sanitizing its inputs, which is how the attacker is able to execute the script in the context of the user's browser session.
References: The EC-Council's Certified SOC Analyst (CSA) program covers various types of cyberattacks, including XSS attacks. The CSA course materials and study guides provide detailed information on identifying, mitigating, and preventing such attacks, as well as best practices for securing web applications against them.

NEW QUESTION # 124
A rapidly growing e-commerce company wants to implement a SIEM solution to improve its security posture and comply with PCI DSS requirements. They need a solution that offers both the necessary technological features and the expertise to manage the system effectively. They also need continuous compliance support and data security assistance. Which SIEM solution is appropriate for this company?
- A. In-house SIEM
- B. Managed SIEM
- C. Cloud-based SIEM
- D. Security analytics
Answer: B
Explanation:
A managed SIEM provides both the technology platform and the operational expertise to run it effectively, which aligns with the company's need for features plus ongoing management, compliance support, and security assistance. Rapidly growing organizations often struggle to staff SIEM engineering, content tuning, and 24/7 monitoring internally. Managed SIEM offerings typically include onboarding data sources, maintaining parsers, tuning detections, handling alert triage, producing compliance reports, and advising on remediation-capabilities that directly support PCI DSS requirements and continuous audit readiness. A cloud-based SIEM is a deployment model and can be part of the answer, but it does not guarantee expert management or compliance support unless paired with a managed service. An in-house SIEM requires building and maintaining internal expertise, which conflicts with the stated need for external expertise and continuous support. "Security analytics" is a capability category, not a full SIEM solution model. From a SOC operations standpoint, managed SIEM reduces time-to-value, improves alert quality through professional tuning, and provides consistent reporting and operational coverage without needing the company to immediately build a mature internal SOC function.
NEW QUESTION # 125
SecureTech Solutions, a managed security service provider (MSSP), is optimizing its log management architecture to enhance log storage, retrieval, and analysis efficiency. The SOC team needs logs stored in a structured or semi-structured format for easy parsing, querying, and correlation. They choose a format that organizes data in a text file in a tabular structure, where each log entry is stored in rows and columns, and that supports easy export to databases or spreadsheet analysis while maintaining readability. Which log format should they choose?
- A. Syslog format
- B. Cloud storage
- C. Database
- D. Comma-Separated Values (CSV) format
Answer: D
Explanation:
CSV is a structured, tabular text format where each record is a row and fields are separated by commas, making it easy to parse, import into spreadsheets, and export into databases. The scenario specifically calls for a text file with rows and columns, readability, and easy export to databases or spreadsheet-based analysis- these are classic CSV strengths. Cloud storage is a storage location/architecture, not a log format. Syslog is a transport and message format family used for sending event messages from systems and network devices; it is often semi-structured but not inherently "rows and columns" in a tabular file structure. A database is a storage system rather than a file format; while logs can be stored in databases, the question asks specifically for a text file format. In SOC practice, CSV is commonly used for exporting specific datasets for reporting, offline analysis, and sharing with stakeholders, especially when interoperability is needed. For high-scale SIEM ingestion, formats like JSON are often preferred, but given the explicit requirement for a tabular text file compatible with spreadsheets, CSV is the correct choice.
NEW QUESTION # 126
Rinni, SOC analyst, while monitoring IDS logs detected events shown in the figure below.
What does this event log indicate?
- A. XSS Attack
- B. SQL Injection Attack
- C. Parameter Tampering Attack
- D. Directory Traversal Attack
Answer: C
Explanation:
The event log indicates a ParameterTampering Attack. This type of attack involves the manipulation of parameters exchanged between the client and the server to alter application data, such as user credentials and permissions, product price and quantity, etc. The IDS log entries showing repeated access to the URL "
/OrderDetail.aspx?id=ORDR-001117" with varying order ID values suggest that the attacker is manipulating the 'id' parameter to potentially access or modify order details unauthorizedly.
References The EC-Council's Certified SOC Analyst (CSA) course materials and study guides discuss various types of cyber attacks, including Parameter Tampering, and their characteristics. Additionally, information on this type of attack can be found in resources provided by the OWASP Foundation1.

NEW QUESTION # 127
A leading e-commerce company relies on backend servers for processing customer transactions. You are working with their cybersecurity team as a SOC analyst. One morning, you notice a sharp increase in CPU utilization on one of your backend servers. Your team scans and monitors the server and finds that an unknown process is running, consuming excessive resources. You further perform detailed forensic analysis and identify the presence of an unrecognized scheduled task that triggers a PowerShell script connecting to an unknown IP address. What should you do to confirm whether this is an active attack?
- A. Check file integrity and detect recent unauthorized changes
- B. Analyze the network logs to identify external connections
- C. Analyze the system logs for unauthorized changes
- D. Review user access logs for unauthorized activity
Answer: B
Explanation:
The strongest "must-be-true" confirmation for an active attack in this scenario is evidence of command-and- control (C2) or other suspicious external communication. You already have a scheduled task launching PowerShell and attempting to connect to an unknown IP address, which is a high-signal indicator of malicious automation. The fastest way to validate ongoing activity is to analyze network telemetry (firewall/proxy logs, netflow, EDR network events) to confirm whether outbound connections are occurring, how frequently, and whether data is being transferred. Network logs can reveal destination IP/port, protocols, connection success
/failure, volume, and timing correlation with the scheduled task triggers. File integrity checks and system logs are useful for understanding persistence and modifications, but they may lag behind or miss short-lived network beacons. User access logs help attribute activity but do not directly confirm an active external control channel. From a SOC triage and containment perspective, confirming external connections enables immediate actions such as blocking the destination, isolating the host, and scoping for other systems contacting the same IPs/domains. Therefore, network log analysis is the most direct next step to confirm active malicious behavior.
NEW QUESTION # 128
An attacker exploits the logic validation mechanisms of an e-commerce website. He successfully purchases a product worth $100 for $10 by modifying the URL exchanged between the client and the server.
Original
URL: http://www.buyonline.com/product.aspx?profile=12
&debit=100
Modified URL: http://www.buyonline.com/product.aspx?profile=12
&debit=10
Identify the attack depicted in the above scenario.
- A. Session Fixation Attack
- B. SQL Injection Attack
- C. Parameter Tampering Attack
- D. Denial-of-Service Attack
Answer: C
Explanation:
The scenario described involves an attacker modifying the URL parameters to alter the price of a product, which is a classic example of a Parameter Tampering attack. This type of attack occurs when an attacker manipulates parameters exchanged between client and server in order to modify application data, such as user credentials, permissions, and price of products, as seen in this case.
The original URL indicates that the product price (debit) is set to $100. The attacker has modified this parameter value to $10 in the modified URL, thus exploiting the logic validation mechanism of the e-commerce website to purchase the product at a lower price. This manipulation of parameters is indicative of a Parameter Tampering attack, which is a form of web-based attack where the properties of a web application are altered to achieve unintended outcomes by the attacker.
References: The EC-Council's Certified SOC Analyst (CSA) course material covers various types of cyber attacks, including Parameter Tampering. The CSA study guides and resources provide detailed information on how to identify and respond to such attacks, emphasizing the importance of validating and sanitizing all inputs and parameters to prevent exploitation.
NEW QUESTION # 129
The SOC analyst at a national cybersecurity agency detected unusual system behavior on critical infrastructure servers. Initial scans flagged potential malware activity. Due to the sophisticated nature of the suspected attack, including registry modifications, process injection, and unauthorized tasks, the case was escalated to the forensic team. The forensic team suspects the malware is designed for stealthy data exfiltration. To assess the compromise, they captured system snapshots before and after suspected infection to identify unauthorized changes and anomalies. Which process are they following by capturing and comparing system snapshots to detect unauthorized changes?
- A. Signature-based detection
- B. Digital forensics
- C. Host integrity monitoring
- D. Threat intelligence gathering
Answer: C
Explanation:
Capturing and comparing system snapshots before and after suspected compromise is a core method of host integrity monitoring. The goal is to detect unauthorized changes to critical system components such as registry keys, scheduled tasks, services, binaries, configuration files, and security settings. By comparing a known-good baseline snapshot to a suspected-compromised state, analysts can identify what changed, when it changed (with supporting timestamps), and which changes are anomalous relative to expected patching or administrative activity. While this activity can occur within a broader digital forensics investigation, the specific technique described-baseline comparison to detect unauthorized modification-is integrity monitoring. Signature-based detection focuses on matching known indicators (hashes, strings, known patterns) and does not rely on before/after snapshot comparison. Threat intelligence gathering is about collecting and analyzing information on external threats, not directly comparing host states. From a SOC standpoint, integrity monitoring supports rapid scoping and eradication because it highlights persistence and tampering mechanisms that must be removed and can reveal stealth modifications that evade signature scanners. It also supports compliance requirements by demonstrating configuration control and unauthorized- change detection capabilities.

NEW QUESTION # 131
In which phase of Lockheed Martin's - Cyber Kill Chain Methodology, adversary creates a deliverable malicious payload using an exploit and a backdoor?
- A. Weaponization
- B. Exploitation
- C. Reconnaissance
- D. Delivery
Answer: A
Explanation:
In the Lockheed Martin Cyber Kill Chain Methodology, the phase where an adversary creates a deliverable malicious payload using an exploit and a backdoor is known as the Weaponization phase. This is the second stage of the Cyber Kill Chain, which occurs after the initial Reconnaissance phase. During Weaponization, the attacker prepares a malicious payload that is designed to exploit vulnerabilities in the target system. This payload often includes a backdoor to allow for persistent access to the compromised system.
The Weaponization phase involves the creation of malware tailored to the target's specific vulnerabilities discovered during Reconnaissance. The attacker uses this malware to create a weaponized deliverable, which can be transmitted to the target during the subsequent Delivery phase of the Cyber Kill Chain.
References: The EC-Council SOC Analyst course materials and study guides discuss the Cyber Kill Chain Methodology in detail, including the Weaponization phase. These resources are designed to provide SOC Analysts with the knowledge and skills necessary to identify, analyze, and respond to cyber threats effectively.
For further information, please refer to the official EC-Council Certified SOC Analyst (CSA) study guides and related course materials. Additionally, Lockheed Martin provides resources and an overview of the Cyber Kill Chain on their official website12.
NEW QUESTION # 132
Global Solutions Inc. uses syslog for centralized logging across a geographically diverse network. The SOC team must ensure logs are reliably delivered from remote sites to the central logging server across potentially unreliable network connections. To guarantee consistent and dependable log delivery, which syslog architectural layer should they focus on optimizing and hardening?
- A. Syslog application layer
- B. Syslog management and filtering
- C. Syslog transport layer
- D. Syslog content layer
Answer: C
Explanation:
Reliable delivery across unreliable networks is primarily a transport-layer concern. The syslog transport layer covers how messages are transmitted between devices, relays, and collectors, including protocol choice and delivery assurance. Many syslog deployments default to UDP for simplicity, but UDP is lossy and does not guarantee delivery-problematic for remote sites and compliance-driven logging. Hardening transport typically involves using TCP (reliable delivery), TLS for encryption and integrity, buffering/queueing at relays, retransmission handling, and monitoring of connection health and backlog. The content layer is about message format and fields; management and filtering is about routing and reduction of noise; application layer relates to the syslog-generating and receiving software. Those are important, but they do not address the fundamental need for dependable delivery under network instability. From a SOC perspective, transport reliability directly impacts forensic completeness, alert accuracy, and compliance evidence. Therefore, optimizing and hardening the syslog transport layer is the correct priority.
