Exam Questions

Question 1

Which of the following statements best describes the MITRE ATT&CK framework?
Options
A: It provides a comprehensive method to test the security of applications.
B: It provides threat intelligence sharing and development of action and mitigation strategies.
C: It helps identify and stop enemy activity by highlighting the areas where an attacker functions.
D: It tracks and understands threats and is an open-source project that evolves.
E: It breaks down intrusions into a clearly defined sequence of phases.
Show Answer
Correct Answer:
It tracks and understands threats and is an open-source project that evolves.
Explanation
The MITRE ATT&CK® framework is best described as a globally accessible, curated knowledge base of adversary tactics, techniques, and procedures (TTPs) based on real-world observations. Its primary purpose is to serve as a foundation for threat modeling and methodology, enabling organizations to track and better understand adversary behaviors. It is an open-source project that is continuously updated and evolves with contributions from the global cybersecurity community, ensuring it remains relevant against emerging threats. This dynamic nature is a defining characteristic of the framework.
Why Incorrect Options are Wrong

A. This describes application security testing (AST) methodologies like SAST or DAST. While ATT&CK can inform such tests, it is not a testing method itself.

B. This is a better description of an Information Sharing and Analysis Center (ISAC) or a threat intelligence platform (TIP), which focus on the sharing and dissemination of intelligence.

C. This describes a primary use case or outcome of applying the ATT&CK framework, rather than describing the fundamental nature of the framework itself, which is a knowledge base.

E. This accurately describes the Lockheed Martin Cyber Kill Chain®, which models an intrusion as a linear sequence of phases, unlike the ATT&CK matrix, which is non-sequential.

Question 2

Which of the following entities should an incident manager work with to ensure correct processes are adhered to when communicating incident reporting to the general public, as a best practice? (Select two).
Options
A: Law enforcement
B: Governance
C: Legal
D: Manager
E: Public relations
F: Human resources
Show Answer
Correct Answer:
Legal, Public relations
Explanation
When communicating an incident to the general public, an incident manager must collaborate with specialized teams to ensure the message is both legally sound and effectively managed. The Legal department is critical for reviewing all external communications to ensure compliance with data breach notification laws and to mitigate legal liability. The Public Relations department is responsible for crafting the message, managing media inquiries, and preserving the organization's reputation. This dual-pronged approach ensures that public statements are accurate, compliant, and strategically delivered to maintain public trust.
Why Incorrect Options are Wrong

A. Law enforcement: Law enforcement is an external agency to be notified if a crime has occurred, not an internal entity that approves the organization's public communication process.

B. Governance: Governance provides the high-level framework and policies, but the specific, operational task of crafting and approving public statements falls to legal and PR teams.

D. Manager: This option is too vague. The incident manager is a manager who coordinates with other specific functional leads, such as the heads of legal and public relations.

F. Human resources: Human resources primarily handles internal communications and personnel-related matters, not external communications with the general public regarding a security incident.

Question 3

A security analyst observed the following activity from a privileged account: . Accessing emails and sensitive information . Audit logs being modified . Abnormal log-in times Which of the following best describes the observed activity?
Options
A: Irregular peer-to-peer communication
B: Unauthorized privileges
C: Rogue devices on the network
D: Insider attack
Show Answer
Correct Answer:
Insider attack
Explanation
The observed activities are classic indicators of an insider attack. A privileged account, which has legitimate, high-level access, is being used for malicious purposes. Accessing sensitive information unrelated to job duties, modifying audit logs to conceal actions, and logging in at abnormal times are all hallmark behaviors of an insider threat. This threat could be a malicious employee or an external attacker who has compromised an insider's credentials and is masquerading as them. The core issue is the abuse of authorized, privileged access.
Why Incorrect Options are Wrong

A. Irregular peer-to-peer communication: The evidence describes data access and log manipulation, not a specific network communication pattern like P2P file sharing.

B. Unauthorized privileges: The account is described as "privileged," meaning it already has high-level access. The issue is the abuse of existing privileges, not the acquisition of new, unauthorized ones.

C. Rogue devices on the network: The activity is tied to a user account, not an unauthorized piece of hardware. There is no information suggesting a new or unknown device is present.

Question 4

A penetration tester submitted data to a form in a web application, which enabled the penetration tester to retrieve user credentials. Which of the following should be recommended for remediation of this application vulnerability?
Options
A: Implementing multifactor authentication on the server OS
B: Hashing user passwords on the web application
C: Performing input validation before allowing submission
D: Segmenting the network between the users and the web server
Show Answer
Correct Answer:
Performing input validation before allowing submission
Explanation
The ability to supply crafted data to a web form and subsequently extract user credentials is characteristic of an injection-class vulnerability (e.g., SQL injection). The primary defense recommended by government and academic security guidance is to enforce rigorous server-side input validation (and associated sanitization/parameterization) before the application processes or stores user-supplied data. Implementing such validation prevents malicious input from being interpreted as executable commands, thereby blocking credential disclosure.
Why Incorrect Options are Wrong

A. Multifactor authentication on the server OS protects logons to the host, not the web application code path exploited by the form.

B. Hashing passwords at rest limits post-compromise damage but does not stop an attacker from exploiting the form to read data before hashing occurs.

D. Network segmentation limits lateral movement; it does not address the direct flaw inside the application logic that allows credential extraction.

Question 5

During a security test, a security analyst found a critical application with a buffer overflow vulnerability. Which of the following would be best to mitigate the vulnerability at the application level?
Options
A: Perform OS hardening.
B: Implement input validation.
C: Update third-party dependencies.
D: Configure address space layout randomization.
Show Answer
Correct Answer:
Implement input validation.
Explanation
A buffer overflow occurs when an application attempts to write more data to a memory buffer than it can hold, overwriting adjacent memory. The most effective mitigation at the application level is to implement robust input validation. This secure coding practice involves checking all data received by the application for proper type, length, and format before it is processed. By ensuring that input does not exceed the buffer's allocated size, input validation directly prevents the overflow condition from occurring, thus addressing the root cause of the vulnerability within the application's code.
Why Incorrect Options are Wrong

A. Perform OS hardening.

This is a system-level, not an application-level, mitigation. It strengthens the operating system but does not fix the underlying coding flaw in the application itself.

C. Update third-party dependencies.

This is only effective if the buffer overflow vulnerability exists within a third-party library the application uses, not in the application's own custom code.

D. Configure address space layout randomization.

Address Space Layout Randomization (ASLR) is an OS-level memory-protection feature that makes exploitation more difficult but does not prevent the buffer overflow from happening.

Question 6

An organization discovered a data breach that resulted in Pll being released to the public. During the lessons learned review, the panel identified discrepancies regarding who was responsible for external reporting, as well as the timing requirements. Which of the following actions would best address the reporting issue?
Options
A: Creating a playbook denoting specific SLAs and containment actions per incident type
B: Researching federal laws, regulatory compliance requirements, and organizational policies to document specific reporting SLAs
C: Defining which security incidents require external notifications and incident reporting in addition to internal stakeholders
D: Designating specific roles and responsibilities within the security team and stakeholders to streamline tasks
Show Answer
Correct Answer:
Researching federal laws, regulatory compliance requirements, and organizational policies to document specific reporting SLAs
Explanation
The core problem identified in the lessons learned review is a lack of clarity on who was responsible for external reporting and the timing requirements for a PII breach. These timing requirements (SLAs) are not arbitrary; they are dictated by legal and regulatory frameworks (e.g., GDPR, CCPA, HIPAA). Therefore, the most fundamental and effective action is to research these external mandates and internal policies. This research provides the authoritative basis for documenting the correct reporting timelines and subsequently assigning clear roles and responsibilities, directly addressing both discrepancies identified.
Why Incorrect Options are Wrong

A. This is too broad. While creating a playbook is useful, it doesn't address the root cause of where the reporting SLAs originate, and it incorrectly bundles containment with the reporting issue.

C. This action only defines which incidents require reporting, but the question's scenario already implies reporting was needed. It fails to address the specific problems of "who" and "when."

D. This addresses the "who" (roles) but completely ignores the "timing requirements," which was an equally critical part of the identified problem. Assigning a role without defining the deadline is an incomplete solution.

Section 4, "The notification process," details the legal timelines for reporting under regulations like the GDPR (e.g., "without undue delay and, where feasible, not later than 72 hours after having become aware of it"). This shows that reporting SLAs are derived directly from regulatory compliance research.

This academic journal discusses how incident response is heavily influenced by regulatory environments, stating, "state and federal laws require firms to notify individuals and government agencies of a breach," which reinforces the need to research these laws to define response procedures.

Question 7

Which of the following would an organization use to develop a business continuity plan?
Options
A: A diagram of all systems and interdependent applications
B: A repository for all the software used by the organization
C: A prioritized list of critical systems defined by executive leadership
D: A configuration management database in print at an off-site location
Show Answer
Correct Answer:
A prioritized list of critical systems defined by executive leadership
Explanation
The foundation of a business continuity plan (BCP) is the Business Impact Analysis (BIA). A BIA's primary output is the identification and prioritization of critical business functions and the information systems that support them. This prioritization, defined and approved by executive leadership, dictates the recovery strategies, recovery time objectives (RTO), and resource allocation detailed in the BCP. Without this prioritized list, an organization cannot effectively plan which operations to restore first to minimize impact during a disruption.
Why Incorrect Options are Wrong

A. A diagram of all systems and interdependent applications is a technical artifact for recovery but lacks the business-driven prioritization that guides the BCP.

B. A repository for all the software used by the organization is an element of disaster recovery, not the strategic input for creating the BCP.

D. A configuration management database (CMDB) provides technical details but does not define the business criticality or recovery priority of systems.

Question 8

A security analyst reviews the following results of a Nikto scan: Analyst+ CS0-003 exam question Which of the following should the security administrator investigate next?
Options
A: tiki
B: phpList
C: shtml.exe
D: sshome
Show Answer
Correct Answer:
shtml.exe
Explanation
The Nikto scan output flags /cgi-bin/shtml.exe as a script potentially vulnerable to cross-site scripting (XSS). The Common Gateway Interface (CGI) directory is designed to execute scripts and programs on the server. The presence of an executable file (.exe), especially one flagged with a potential vulnerability, represents a high-priority threat. Such a vulnerability could be leveraged for remote code execution (RCE), allowing an attacker to run arbitrary commands on the server. This risk is significantly more severe than the information disclosure or configuration weaknesses identified for the other options, making it the most critical item for immediate investigation.
Why Incorrect Options are Wrong

A. tiki: The finding for TikiWiki is a missing .htaccess file, which is a medium-risk configuration issue but less urgent than a potentially executable vulnerability.

B. phpList: The scan only identifies the presence of the application and its admin directory, which is a low-risk information disclosure finding.

D. sshome: The scan merely reports the installation of Sshome without noting any specific vulnerabilities, making it the lowest priority among the choices.

References

It states, "The cgi-bin directory is a special directory in the root of the web server that is used to house scripts that are to be executed by the web server... Misconfigured or legacy scripts could be abused by an attacker to gain control of the web server." The presence of shtml.exe directly aligns with this high-risk scenario.

2. NIST Special Publication 800-115, "Technical Guide to Information Security Testing and Assessment," Section 5.5.2, "Web Application Scanning": This document outlines the process of security testing, which includes analyzing scanner output. The methodology implicitly requires prioritizing findings based on potential impact. A vulnerability that could lead to code execution (like a flawed CGI executable) would be ranked higher than information disclosure or missing security headers.

3. Carnegie Mellon University, Software Engineering Institute (SEI), "Vulnerability Analysis," Courseware Module: University-level cybersecurity courseware emphasizes the principle of prioritizing vulnerabilities based on exploitability and impact. A server-side executable script in a cgi-bin directory presents a direct vector for server compromise, making it a critical finding that requires immediate attention over less severe configuration issues.

Question 9

A cybersecurity analyst is doing triage in a SIEM and notices that the time stamps between the firewall and the host under investigation are off by 43 minutes. Which of the following is the most likely scenario occurring with the time stamps?
Options
A: The NTP server is not configured on the host.
B: The cybersecurity analyst is looking at the wrong information.
C: The firewall is using UTC time.
D: The host with the logs is offline.
Show Answer
Correct Answer:
The NTP server is not configured on the host.
Explanation
A time discrepancy of 43 minutes is arbitrary and does not correspond to a standard time zone offset, which would typically be in full or half-hour increments. This strongly suggests that one of the devices is experiencing clock drift due to a lack of time synchronization. The Network Time Protocol (NTP) is the standard used to synchronize clocks across a network. In a typical corporate environment, critical infrastructure like a firewall is properly configured with NTP. Therefore, the most probable cause is that the host's clock is not synchronized with an NTP server, causing it to drift over time and creating a time gap when its logs are correlated with other sources in the SIEM.
Why Incorrect Options are Wrong

B. This suggests human error, but the question asks for the most likely scenario occurring with the time stamps, implying a technical cause for the discrepancy itself.

C. A difference between UTC and a local time zone would result in an offset of one or more full hours (or half-hours), not an arbitrary value like 43 minutes.

D. A host being offline would mean it stops sending logs, but it does not explain why the timestamps in the logs it already sent are out of sync.

Section 4.3.1, Time Stamps, Page 4-4: "If the clocks on hosts are not synchronized, it is impossible to have a consistent time reference... The Network Time Protocol (NTP) is typically used to perform time synchronization. Without proper time synchronization, it is impossible to determine the order in which events occurred from their log entries." This directly supports that a lack of synchronization (via NTP) causes time reference issues, which is the root of the problem in the scenario.

Section 2.3, Page 10: This objective requires the candidate to "analyze data as part of security monitoring activities," specifically mentioning "Log - Timestamps." The scenario directly tests the analyst's ability to interpret and troubleshoot issues with log timestamps, a core competency for the exam. The discrepancy points to a failure in the underlying mechanism (NTP) responsible for maintaining accurate timestamps.

Question 10

Each time a vulnerability assessment team shares the regular report with other teams, inconsistencies regarding versions and patches in the existing infrastructure are discovered. Which of the following is the best solution to decrease the inconsistencies?
Options
A: Implementing credentialed scanning
B: Changing from a passive to an active scanning approach
C: Implementing a central place to manage IT assets
D: Performing agentless scanning
Show Answer
Correct Answer:
Implementing a central place to manage IT assets
Explanation
The core issue described is a lack of a consistent, shared understanding of the IT infrastructure across different teams, leading to disagreements when vulnerability reports are reviewed. Implementing a central place to manage IT assets, such as a Configuration Management Database (CMDB) or an asset inventory system, establishes a single, authoritative source of truth. This ensures that the vulnerability assessment team, system administrators, and other stakeholders are all working from the same baseline data regarding hardware, software versions, and patch status. This foundational step directly resolves the root cause of the inconsistencies between teams.
Why Incorrect Options are Wrong

A. Implementing credentialed scanning: While credentialed scanning provides more accurate data for the vulnerability report, it does not solve the underlying problem of different teams having inconsistent views of the asset inventory itself.

B. Changing from a passive to an active scanning approach: This changes the data collection method but does not address the foundational need for an agreed-upon asset inventory, which is the source of the inter-team inconsistencies.

D. Performing agentless scanning: This is a deployment choice for how scans are conducted. It does not inherently solve the problem of inconsistent asset information between different organizational teams.
