ECCouncil 312-39 Exam Dumps & Practice Test Questions
Question No 1:
Which cybersecurity tool is specifically designed to deceive attackers by simulating a legitimate, vulnerable system, thereby attracting them to interact with it rather than with critical systems?
A. De-Militarized Zone (DMZ)
B. Firewall
C. Honeypot
D. Intrusion Detection System (IDS)
Correct Answer: C. Honeypot
Explanation:
A honeypot is a security mechanism intentionally created to act as a decoy and lure cyber attackers. It is configured to appear like a legitimate, vulnerable system or service. The primary purpose of a honeypot is to mislead attackers, detect malicious activities, and collect information on unauthorized access or cyberattacks, without risking the actual network or sensitive data.
Unlike traditional security tools such as firewalls or intrusion detection systems (IDS), which focus on protecting and defending systems, a honeypot takes on a more offensive approach. By mimicking security weaknesses like open ports or system vulnerabilities, it entices attackers into interacting with it. Once attackers engage, all of their actions can be logged and analyzed to gather insights on attack techniques and tools.
For example, when an attacker scans for vulnerabilities or tries to deploy malware on the honeypot, these actions are captured and logged in detail. This valuable information aids cybersecurity professionals in strengthening defenses and understanding the evolving tactics of attackers. Importantly, honeypots are isolated from real systems, so any breach into a honeypot does not affect actual assets.
Comparison with Other Options:
DMZ (Demilitarized Zone): A network segment that functions as a buffer between internal systems and the external internet, typically used for hosting public-facing services.
Firewall: A security barrier that monitors and controls incoming and outgoing network traffic based on predefined security rules.
Intrusion Detection System (IDS): A system that monitors network traffic for suspicious activity but does not engage attackers or deceive them.
In summary, honeypots are an effective tool for proactively learning from cyber attackers in a controlled environment, without jeopardizing real systems.
Question No 2:
In Windows Event Viewer, system administrators track event severity levels to diagnose issues and anticipate potential problems within the operating system. Each event is classified by severity, ranging from informational messages to critical system failures.
Which severity level in Windows logs is used to report events that aren't immediately critical, but could indicate potential problems if not addressed?
A. Failure Audit
B. Warning
C. Error
D. Information
Correct Answer: B. Warning
Explanation:
Windows Event Viewer is a tool that records detailed logs about system, application, and security events. These events are categorized into different severity levels to help administrators prioritize their responses and resolve issues efficiently.
The "Warning" severity level indicates that an event isn't an immediate threat but may point to an issue that could worsen if not addressed. For instance, a warning might be triggered if the system is running low on disk space, experiencing intermittent network issues, or encountering periodic service failures. These warnings do not disrupt system functionality, but they serve as an early warning that something could go wrong in the near future.
Comparison with Other Options:
Failure Audit (A): This type of log records failed security attempts to access system resources, focusing on unauthorized access rather than system health or future risks.
Error (C): This severity level represents significant issues, such as application crashes, service failures, or hardware malfunctions. These events typically demand immediate attention.
Information (D): This level logs routine system events, such as successful service starts or user logins. These are purely informational and do not indicate any problems.
Thus, "Warning" is the correct severity level to indicate events that might lead to issues if ignored, allowing administrators to take proactive steps to prevent further complications or system downtime.
Question No 3:
Which of the following factors plays a crucial role when deciding on the proper Security Information and Event Management (SIEM) architecture for an organization?
A. SMTP Configuration
B. DHCP Configuration
C. DNS Configuration
D. Network Topology
Correct Answer: D. Network Topology
Explanation:
When implementing a Security Information and Event Management (SIEM) solution, one of the most significant aspects to consider is the organization’s network topology. SIEM systems are pivotal in cybersecurity because they aggregate, analyze, and correlate log data from various network sources. The network’s structure, including its layout, connectivity, and communication paths, greatly influences the SIEM's effectiveness in terms of performance, scalability, and reliability.
The network topology determines how data from endpoints, servers, applications, firewalls, and other infrastructure components is directed to the SIEM. In large or distributed environments, decisions must be made regarding whether to adopt a centralized or decentralized SIEM architecture. A centralized system may be optimal for single-location setups, while a distributed system might be necessary for multi-location environments to minimize latency and optimize bandwidth.
On the other hand, while SMTP, DHCP, and DNS configurations are essential components of the broader IT infrastructure, they are not key considerations when determining the architecture of a SIEM. For example:
SMTP deals with email service configurations.
DHCP manages the assignment of IP addresses.
DNS handles domain name resolution.
Though these services may produce logs that the SIEM collects, they do not affect how the SIEM architecture itself should be designed.
In conclusion, network topology is the most important factor when determining the appropriate SIEM setup, as it directly affects how data flows through the system and how efficiently it can be processed and analyzed.
Question No 4:
What does the HTTP status code 403 signify when a user encounters it while trying to access a web page? Select the correct option and explain its role in web communication.
A. Unauthorized Error
B. Not Found Error
C. Internal Server Error
D. Forbidden Error
Correct Answer: D. Forbidden Error
Explanation:
The HTTP status code 403 indicates a "Forbidden Error," meaning the server understands the client's request, but it refuses to authorize it. This is distinct from a 401 Unauthorized error, where the server expects authentication, but it’s either not provided or incorrect. A 403 error specifically means that even if the correct credentials are provided, access is explicitly denied.
When a user encounters a 403 Forbidden error, it typically means they do not have the required permissions to access the requested content. This could be due to restrictions set by the website administrator based on factors like IP address, user role, or other security rules. The server may block access to protect sensitive information or specific functionality.
Common causes of a 403 error include:
Attempting to access restricted directories or files on the server.
Incorrect file or folder permissions on the server.
Server configuration settings (such as .htaccess rules in Apache) that restrict access.
IP blocking or user-agent-based restrictions set by the server administrator.
This status code is part of the 4xx class of HTTP responses, which typically signal client-side issues. However, with the 403 error, the client’s request is valid, but the server is refusing to allow it.
Understanding HTTP status codes like 403 is essential for web developers, system administrators, and cybersecurity professionals. It helps troubleshoot access problems, ensure proper security measures are in place, and provide users with clear feedback when access is blocked.
In summary, the HTTP 403 status code is a critical indicator that the server is denying access to the requested resource, even if the user is authenticated.
Question No 5:
Which Windows Security Event ID is logged when a user attempts to access a registry key, indicating that a handle to an object (like a registry key) was requested, typically for reading, writing, or executing?
A. Event ID 4656
B. Event ID 4663
C. Event ID 4660
D. Event ID 4657
Correct Answer: A. Event ID 4656
Explanation:
Windows systems utilize Event IDs to log and track system activities for auditing and troubleshooting purposes. When monitoring access to objects like registry keys, specific Event IDs are triggered based on the type of action.
Event ID 4656 is logged when a handle to an object, such as a file or registry key, is requested, indicating that an application or user is attempting to open or access that object. This event is crucial for object access auditing, particularly when trying to identify unauthorized access attempts to sensitive registry keys or configuration settings.
Event ID 4656 provides key information such as:
The name of the accessed object (e.g., a registry key)
The user account requesting access
The type of access permissions requested
The access mask (showing the specific requested rights)
The process ID and name of the requester
This event is logged before access is granted, making it an important tool for proactive auditing. Security administrators can use this to detect unauthorized attempts to read or modify critical registry keys tied to system configurations, startup processes, or security settings.
Other Event IDs mentioned serve different purposes:
Event ID 4663 logs when an object is already opened and accessed.
Event ID 4660 logs when an object is deleted.
Event ID 4657 logs modifications made to registry values, not just access attempts.
In summary, Event ID 4656 is key to identifying when a handle to a registry key is requested, making it vital for monitoring access to system configurations and detecting unauthorized attempts.
Question No 6:
Which of the following actions are typically carried out by SIEM agents before sending data to the central SIEM engine?
Collecting logs and event data from various systems and devices.
Normalizing the collected data into a standardized format for analysis.
Correlating events to identify potential security threats.
Visualizing the collected data through graphical dashboards or interfaces.
Select the correct combination:
A. 1 and 2
B. 2 and 3
C. 1 and 4
D. 3 and 1
Correct Answer: A. 1 and 2
Explanation:
SIEM (Security Information and Event Management) systems are essential in modern cybersecurity frameworks, providing centralized monitoring, detection, and analysis of security events across an organization’s IT infrastructure. SIEM agents are distributed software components installed on various endpoints, servers, or network devices. Their primary function is to collect and prepare security data for the central SIEM engine.
Two of the key functions of SIEM agents are:
Data Collection: SIEM agents gather logs and event data from various sources, including firewalls, intrusion detection systems, antivirus programs, operating systems, and applications. This data is essential for detecting suspicious behavior, security breaches, and malicious activities.
Data Normalization: After collection, agents often normalize the data, converting it from various formats into a consistent, structured format that the SIEM engine can analyze. Normalization ensures that data from different sources can be processed in a standardized way, facilitating better correlation and analysis by the central engine.
On the other hand, correlation and visualization are not typically tasks handled by SIEM agents:
Correlation: This involves analyzing normalized data from various sources to detect patterns indicative of security threats, which is typically done by the central SIEM engine due to its higher computational capabilities.
Visualization: Displaying data through dashboards and charts is usually managed by the SIEM console or user interface, rather than by the agent itself.
Thus, Option A (1 and 2) correctly reflects the tasks typically performed by SIEM agents, making it the right answer.
Question No 7:
Sam, a security analyst at INFOSOL INC., was reviewing IIS (Internet Information Services) web server logs as part of his regular monitoring tasks when he noticed a suspicious HTTP request. The request contained a string that matched the following regular expression (regex):
/\w*((%27)|(\’))((%6F)|o|(%4F))((%72)|r|(%52))/ix
After further investigation, Sam suspects that this pattern could indicate a possible web-based attack. As part of his analysis, he needs to determine the type of threat associated with this log entry.
What type of attack is most likely indicated by this observed pattern?
A. SQL Injection Attack
B. Parameter Tampering Attack
C. Cross-Site Scripting (XSS) Attack
D. Directory Traversal Attack
Correct Answer: A. SQL Injection Attack
Explanation:
The regex pattern identified in the IIS logs is:
/\w*((%27)|(\’))((%6F)|o|(%4F))((%72)|r|(%52))/ix
Here’s a breakdown of the regex:
\w* – Matches any number of word characters (letters, digits, or underscores).
(%27)|(\’) – Matches either "%27" (the URL-encoded version of a single quote ') or a typographic apostrophe.
((%6F)|o|(%4F)) – Matches "%6F", "o", or "%4F" (representing the letter "o").
((%72)|r|(%52)) – Matches "%72", "r", or "%52" (representing the letter "r").
When combined, this regex looks for input such as:
' or '1'='1
This is a well-known pattern associated with SQL Injection, where malicious SQL code is inserted into a query through user input fields. The use of URL-encoded characters and the keyword "or" strongly suggest an attempt to manipulate or bypass authentication or retrieve unauthorized data via SQL queries.
SQL Injection attacks are common vulnerabilities that occur when an application does not properly validate or sanitize user input, allowing attackers to insert arbitrary SQL code. This type of attack can lead to unauthorized data access, corruption, or even total database compromise.
Thus, the correct answer is A. SQL Injection Attack.
Question No 8:
Which of the following frameworks focuses specifically on evaluating and improving the maturity and effectiveness of an organization's security engineering practices, ensuring that essential security engineering processes are in place and properly managed?
A. COBIT
B. ITIL
C. SSE-CMM
D. SOC-CMM
Correct Answer: C. SSE-CMM
Explanation:
The correct answer is SSE-CMM (Systems Security Engineering Capability Maturity Model). This framework is designed specifically to assess and improve the maturity of an organization's security engineering processes.
SSE-CMM provides a structured methodology for evaluating and enhancing the practices used to build secure systems. It outlines 22 process areas, such as risk management, configuration management, and incident response, all aimed at strengthening how organizations integrate security into their systems from the ground up.
The primary goal of SSE-CMM is not to dictate specific security implementation details but to ensure that security engineering practices are being followed consistently across all technologies and domains. It helps organizations assess their existing capabilities and identify potential gaps that may lead to vulnerabilities if not addressed.

Ensure consistency, repeatability, and quality in their security engineering efforts.
Let’s differentiate SSE-CMM from other frameworks:
COBIT (Control Objectives for Information and Related Technologies) is a governance framework focused on IT management and control.
ITIL (Information Technology Infrastructure Library) is a framework for IT service management, not specifically focused on security engineering.
SOC-CMM (Security Operations Center Maturity Model) assesses the maturity of Security Operations Centers, not the broader security engineering process.
In conclusion, SSE-CMM is uniquely suited for organizations looking to mature their security engineering practices, making it the most appropriate choice for ensuring the effectiveness of security engineering within an organization.
Question No 9:
In the context of Windows security auditing, what does Windows Security Event ID 4740 indicate, and what does it reveal about the status of a user account?
A) A user account was locked out.
B) A user account was disabled.
C) A user account was enabled.
D) A user account was created.
Correct Answer: A
Explanation:
Windows Security Event ID 4740 plays a critical role in auditing security-related events by logging when a user account becomes locked out. This event is generated whenever an account lockout policy is activated, typically after several unsuccessful login attempts within a short duration. The occurrence of this event indicates that either a user or potentially a malicious actor has repeatedly entered incorrect login credentials, triggering the account lockout mechanism.
Event ID 4740 is an essential component of both security monitoring and troubleshooting failed login scenarios. It assists administrators in detecting possible brute-force attacks, misconfigured services, or even users who might have forgotten their credentials. The event record contains important details, such as:
The username of the locked-out account
The time the lockout occurred
The computer from which the lockout originated
The caller computer name, where the authentication attempt took place
This information helps administrators pinpoint the underlying causes of repeated account lockouts. For instance, a mapped drive or a service operating with outdated credentials might continuously trigger login failures, leading to an account being locked. Additionally, malware attempting unauthorized access could also provoke the same result.
To enable logging of Event ID 4740, administrators need to ensure that Audit Account Lockout is activated under the Advanced Audit Policy Configuration in Group Policy.
In conclusion, Event ID 4740 is a crucial tool for enhancing security in Active Directory environments. It enables administrators to detect unusual login activities and respond swiftly to potential security threats, ensuring the integrity of user authentication systems.
