Cybersecurity-Audit-Certificate ISACA Cybersecurity Audit Certificate Exam Questions and Answers

The GREATEST advantage of using a common vulnerability scoring system is that it helps with risk prioritization. This is because a common vulnerability scoring system provides a standardized and consistent way of measuring and comparing the severity of vulnerabilities, based on their impact and exploitability. This allows organizations to prioritize the remediation of the most critical vulnerabilities and allocate resources accordingly. The other options are not as advantageous as using a common vulnerability scoring system, because they either involve aggregating (A), eliminating C, or quantifying (D) risk, which are not directly related to the scoring system.

Availability can be protected through the use of redundancy, backups, and business continuity management. This is because these measures help to ensure that systems, data, and services are accessible and functional at all times, even in the event of a disruption or disaster. The other options are not directly related to protecting availability, but rather focus on enhancing confidentiality (A), integrity C, or awareness (D).

Hashing is a method used to ensure the integrity of digital assets. It involves applying a hash function to the digital asset’s data to produce a unique hash value. This value acts as a digital fingerprint; any alteration to the data will result in a different hash value when the hash function is reapplied. This makes it easy to detect unauthorized changes to the data, thereby protecting the integrity of the digital assets.

References: ISACA’s resources on cybersecurity audit emphasize the importance of using hashing as a control mechanism. Hashing is highlighted as a reliable method for maintaining the integrity of digital assets, as it provides a way to verify that the data has not been tampered with1.

The GREATEST advantage of using a virtual private network (VPN) over dedicated circuits and dial-in servers is that it is more cost effective. This is because a VPN is a technology that creates a secure and encrypted connection between a client and a server over an existing public network, such as the Internet. A VPN reduces the cost of establishing and maintaining a secure communication channel, as it does not require any additional hardware, software, or infrastructure, unlike dedicated circuits and dial-in servers, which require dedicated lines, modems, routers, switches, etc. The other options are not the greatest advantage of using a VPN over dedicated circuits and dial-in servers, because they either involve security (A), reliability (B), or speed C aspects that may not be significantly different or better than dedicated circuits and dial-in servers.

SSH, or Secure Shell, is a network protocol that operates at the Application layer of the OSI model. This is the topmost layer, which allows users to interact with the network through applications. SSH provides a secure channel over an unsecured network in a client-server architecture, enabling users to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another.

References: The information aligns with the OSI model’s definition, where the Application layer is responsible for providing network services to the applications of the user12.

The characteristic of cloud computing that allows users to provision computing capabilities without human interaction from the service provider is known as on-demand self-service. This feature enables users to automatically manage their computing resources, such as server time and network storage, as needed, which provides agility and flexibility in resource management.

References: The National Institute of Standards and Technology (NIST) defines on-demand self-service as one of the five essential characteristics of cloud computing. It specifies that users can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider1234.

The feature of continuous auditing that provides the BEST level of assurance over traditional sampling is that voluminous data can be analyzed at a high speed to show relevant patterns. This is because continuous auditing is a technique that uses automated tools and processes to perform audit activities on a continuous or near-real-time basis, and to analyze large amounts of data from various sources and systems. Continuous auditing helps to provide a higher level of assurance than traditional sampling, by covering the entire population of transactions or events, rather than a subset or sample, and by identifying trends, anomalies, or exceptions that may indicate risks or issues. The other options are not features of continuous auditing that provide the best level of assurance over traditional sampling, but rather different aspects or benefits of continuous auditing, such as reporting frequency (A), reliability (B), or complexity (D).

The FIRST phase of the ISACA framework for auditors reviewing cryptographic environments is inventory and discovery. This is because the inventory and discovery phase helps auditors to identify and document the scope, objectives, and approach of the audit, as well as the cryptographic assets, systems, processes, and stakeholders involved in the cryptographic environment. The inventory and discovery phase also helps auditors to assess the maturity and effectiveness of the cryptographic governance and management within the organization. The other phases are not the first phase of the ISACA framework for auditors reviewing cryptographic environments, but rather follow after the inventory and discovery phase, such as evaluation of implementation details (A), hands-on testing (B), or risk-based shakeout C.

The feature that provides the GREATEST assurance that data can be recovered and restored in a timely manner in the event of data loss is that backups of information are regularly tested. This is because testing backups helps to ensure that they are valid, complete, and usable, and that they can be restored within the expected time frame and without errors or corruption. Testing backups also helps to identify and resolve any issues or problems with the backup process, media, or software. The other options are not features that provide the greatest assurance that data can be recovered and restored in a timely manner in the event of data loss, but rather different aspects or factors that affect the backup process, such as availability (B), execution C, or frequency (D) of backups.

The device that is at GREATEST risk from activity monitoring and data retrieval is mobile devices. This is because mobile devices are devices that are portable, wireless, and connected to the Internet or other networks, such as smartphones, tablets, laptops, etc. Mobile devices are at greatest risk from activity monitoring and data retrieval, because they can be easily lost, stolen, or compromised by attackers who can access or extract the data stored or transmitted on the devices. Mobile devices can also be subject to activity monitoring and data retrieval by third-party applications or services that may collect or share the user’s personal or sensitive information without their consent or knowledge. The other options are not devices that are at greatest risk from activity monitoring and data retrieval, but rather different types of devices that may have different levels of risk or protection from activity monitoring and data retrieval, such as cloud storage devices (B), desktop workstations C, or printing devices (D).

An attack is the actual occurrence of a threat, which is a potential activity that could harm an asset. An attack is the result of a threat actor exploiting a vulnerability in a system or network to achieve a malicious objective. For example, a denial-of-service attack is the occurrence of a threat that aims to disrupt the availability of a service.

The MOST important factor to ensure the successful implementation of continuous auditing is top management support. This is because top management support helps to provide the vision, direction, and resources for implementing continuous auditing within the organization. Top management support also helps to overcome any resistance or challenges that may arise from implementing continuous auditing, such as cultural change, stakeholder buy-in, process reengineering, etc. Top management support also helps to ensure that the results and findings of continuous auditing are communicated and acted upon by the relevant decision-makers and stakeholders. The other options are not factors that are more important than top management support for ensuring the successful implementation of continuous auditing, but rather different aspects or benefits of continuous auditing, such as storage hardware (A), technical resources (B), or processing capacity (D).

An insecure wireless connection, such as one that lacks encryption, can allow unauthorized individuals within range to intercept the data being transmitted. This interception is known as eavesdropping. It is a common security risk associated with wireless networks where attackers can capture sensitive information without being detected.

References: The ISACA resources highlight the importance of securing wireless connections to prevent unauthorized access and data interception. Specifically, ISACA’s materials on cybersecurity audit emphasize the need to address threats to information processed, stored, and transported by internetworked information systems, which includes protecting against eavesdropping12. Additionally, the risks associated withinsecure wireless connections, such as eavesdropping, are discussed in the context of mobile computing device threats and vulnerabilities3.

The MOST important thing for an IS auditor to consider in an assessment of the potential risk factors when a cloud service provider has not adequately secured its application programming interface (API) is the impact on the confidentiality, integrity, and availability of the cloud service. An API is a set of rules and protocols that allows communication and interaction between different software components or systems. An API is often used by cloud service providers to enable customers to access and manage their cloud resources and services. However, if an API is not adequately secured, it can expose the cloud service provider and its customers to various threats,such as unauthorized access, data breaches, tampering, denial-of-service attacks, or malicious code injection.

 The responsibility of an organization to protect its assets, including IT infrastructure and information, falls under the broader umbrella of governance, risk management, and compliance (GRC). Governance ensures that organizational activities, like managing IT operations, are aligned with the business’s goals, risk management involves identifying, assessing, and mitigating risks, and compliance ensures that the organization adheres to laws, regulations, and policies.

References = While I can’t provide direct references from the Cybersecurity Audit Manual, the concept of GRC is widely recognized in cybersecurity frameworks and best practices, such as those outlined by ISACA and other industry standards.

A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It establishes a barrier between a secure internal network and an untrusted external network, such as the internet. This system is designed to prevent unauthorized access to or from private networks and is a fundamental piece of a comprehensive security framework for any organization.

References: The concept of a firewall as a system that enforces a boundary between networks is well-established in cybersecurity literature. It is recognized as a critical component for protecting network resources by filtering traffic and blocking unauthorized access while allowing legitimate communication to pass123.

When defining actions for an IDS policy, the most important consideration is the level of risk to the organization’s data. This involves assessing the potential impact of the intrusion on the confidentiality, integrity, and availability of data, which guides the prioritization and response efforts.

References = ISACA’s guidance on cybersecurity incident response highlights the importance of understanding the risk to data as a key factor in shaping the response to intrusions. This includes evaluating the severity of the threat and the sensitivity of the affected data to determine the appropriate actions123.

The FIRST activity associated with a successful cyber attack is reconnaissance. This is because reconnaissance is a phase of the cyber attack lifecycle that involves gathering information about the target organization or system, such as its network topology, IP addresses, open ports, services, vulnerabilities, etc. Reconnaissance helps to identify potential entry points and weaknesses that can be exploited by the attackers in later phases of the attack. The other options are not the first activity associated with a successful cyber attack, but rather follow after reconnaissance in the cyber attack lifecycle, such as exploitation (A), maintaining a presence C, or creating attack tools (D).

 Continuous auditing tools are designed to monitor and analyze business transactions on an ongoing basis. An automated GRC tool fits this description as it can scan and flag transactions according to predefined criteria in real-time. This is in contrast to vulnerability scanners, IDS, or antivirus tools, which serve different purposes such as scanning for system weaknesses, detecting unauthorized access, or protecting against malware, respectively.

References: The information aligns with the principles of continuous auditing, which involves the examination of accounting practices, risk controls, compliance, information-technology systems, and business procedures on an ongoing basis123. Continuous auditing tools, like an automated GRC tool, enable real-time monitoring and analysis, which is essential for maintaining compliance and managing risk effectively3.

The intrusion detection system component that is responsible for collecting data in the form of network packets, log files, or system call traces is sensors. This is because sensors are components of an intrusion detection system that are deployed on various locations or points of the network or system, such as routers, switches, servers, etc., and that capture and collect data from the network traffic or system activities. Sensors then forward the collected data to another component of the intrusion detection system, such as analyzers, for further processing and analysis. The other options are not components of an intrusion detection system that are responsible for collecting data in the form of network packets, log files, or system call traces, but rather different components or techniques that are related to intrusion detection or prevention, such as packet filters (A), analyzers (B), or administration modules C.

The GREATEST risk pertaining to sensitive data leakage when users set mobile devices to “always on” mode is that authorization tokens could be exploited. Authorization tokens are pieces of data that are used to authenticate users and grant them access to certain resources or services. Authorization tokens are often stored on mobile devices to enable seamless and convenient access without requiring users to enter their credentials repeatedly. However, if users set their mobile devices to “always on” mode, they increase the risk of losing their devices or having them stolen by attackers. Attackers can then access the authorization tokens stored on the devices and use them to impersonate the users or access their sensitive data.

Secret key encryption, also known as symmetric encryption, involves a single key for both encryption and decryption. This method provides the best protection for data on a computer that is stolen because it renders the data unreadable without the key. Even if the thief has access to the physical hardware, without the secret key, the data remains secure and inaccessible.

References: ISACA’s resources emphasize the importance of encryption in protecting information assets. Encryption is a critical control for ensuring the confidentiality and integrity of data, especially for devices that may be lost or stolen. The use of secret key encryption is a widely recommended practice for safeguarding sensitive data on mobile devices and laptops as part of an organization’s data protection strategy123.

Broad network access refers to the computing capabilities that are available over a network and can be accessed by diverse client platforms, such as personal computers, mobile phones, and tablets. This characteristic is one of the essential features of cloud computing, which allows users to access services using a variety of devices through standard mechanisms.

References: The concept of broad network access is integral to the understanding of cloud services and is often discussed in cybersecurity resources, including those provided by ISACA, which emphasize the importance of securing access to these services across different platforms1

When fraud has been detected following an incident, a forensics audit is the most relevant type of audit to conduct. A forensics audit is specifically designed to investigate and uncover evidence of fraud, misconduct, or other financial crimes. It involves the use of auditing and investigative skills to examine financial records, identify irregularities, and gather evidence that can be used in legal proceedings1.

References: The information aligns with the guidance provided by ISACA, which suggests that when fraud is suspected or detected, an audit should focus on the forensic examination of the evidence to understand the nature of the fraud and to gather proof1. Additionally, the role of internal audit in such cases is to assess the controls in place to prevent fraud and not necessarily to investigate the fraud itself unless they have the specific experience and expertise required1.

The FIRST phase of the ISACA framework for auditors reviewing cryptographic environments is inventory and discovery. This is because the inventory and discovery phase helps auditors to identify and document the scope, objectives, and approach of the audit, as well as the cryptographic assets, systems, processes, and stakeholders involved in the cryptographic environment. The inventory and discovery phase also helps auditors to assess the maturity and effectiveness of the cryptographic governance and management within the organization. The other phases are not the first phase of the ISACA framework for auditors reviewing cryptographic environments, but rather follow after the inventory and discovery phase, such as evaluation of implementation details (A), hands-on testing (B), or risk-based shakeout C.

From a regulatory perspective, the MOST important thing for the healthcare organization to determine when outsourcing its patient information processing to a third-party Software as a Service (SaaS) provider is the incident escalation procedures. This is because incident escalation procedures define how security incidents involving patient information are reported, communicated, escalated, and resolved between the healthcare organization and the SaaS provider. This is essential for complying with regulatory requirements such as HIPAA, which mandate timely notification and response to breaches of protected health information. The other options are not as important as incident escalation procedures from a regulatory perspective, because they either relate to technical aspects that may not affect compliance (A, B), or operational aspects that may not affect patient information security (D).

A security setting that locks a profile after a certain number of unsuccessful login attempts is designed to mitigate brute force attacks. In such attacks, an adversary systematically tries numerous combinations of usernames and passwords to gain unauthorized access. By locking the account after several failed attempts, it prevents the attacker from continuing to try different password combinations, thus thwarting the brute force method.

References = This security measure is a common recommendation in cybersecurity practices, including those suggested by ISACA, to protect against brute force attacks. It is an effective control to prevent attackers from continuously attempting to guess a user’s credentials123.

A cloud service provider is used to perform analytics on an organization’s sensitive data. A data leakage incident occurs in the service provider’s network. From a regulatory perspective, the organization is responsible for the data breach. This is because the organization is the data owner and has the ultimate accountability and liability for the security and privacy of its data, regardless of where it is stored or processed. The organization cannot transfer or delegate its responsibility to the service provider, even if there is a contractual agreement or service level agreement that specifies the security obligations of the service provider. The other options are not correct, because they either imply that the service provider is responsible (A), or that the responsibility depends on the nature of breach (B) or specific regulatory requirements C, which are not relevant factors.

The increasing amount of storage space available on mobile devices poses the greatest concern for organizations needing to protect sensitive data. Larger storage capacities allow for more data to be stored on a device, which can include sensitive organizational information. If such a device is lost, stolen, or compromised, the potential for sensitive data to be accessed increases significantly. Additionally, the more data a device can hold, the more attractive it becomes as a target for attackers.

References = ISACA’s resources highlight the risks associated with mobile devices’ storage capabilities, especially when they contain sensitive organizational data. The threats, vulnerabilities, and risks related to the storage of sensitive data on mobile devices are discussed, emphasizing the importance of protecting such data from unauthorized access123.

Data packet analysis is the most helpful feature of an anti-malware application in protecting an organization from the potential of infected computers using a VPN. This feature involves examining the data packets that are being transmitted over the network. By analyzing these packets, the anti-malware can detect malicious activity or anomalies that may indicate an infection. This is particularly important for VPN traffic, as it is encrypted and not easily inspected by traditional methods.

References: The effectiveness of data packet analysis in a VPN context is supported by cybersecurity best practices that emphasize the importance of monitoring and analyzing network traffic to identify and mitigate threats12.

 An incremental backup is a type of backup that only copies the files that have changed since the last backup was made. This means that after a full backup, subsequent incremental backups will only include the data that has been altered or newly created since the previous backup, making it a more efficient way to save storage space and reduce backup time.

References = While I can’t provide direct references from the Cybersecurity Audit Manual, the concept of incremental backups is a standard practice in data management and is covered in various cybersecurity and IT audit resources, including those provided by ISACA1. For a detailed understanding, you may refer to the ISACA Cybersecurity Audit Certificate resources or other ISACA study materials.

The GREATEST drawback when using the AICPA/CICA Trust Services to evaluate a cloud service provider is the lack of specificity in the principles. This is because the AICPA/CICA Trust Services are a set of principles and criteria that provide guidance for evaluating and reporting on controls over information systems and services. However, the principles and criteria are very broad and generic, and do not address the specific risks and challenges that are associated with cloud services, such as data sovereignty, multi-tenancy, portability, etc. The other options are not drawbacks when using the AICPA/CICA Trust Services to evaluate a cloud service provider, but rather different aspects or benefits of using the AICPA/CICA Trust Services to evaluate a cloud service provider, such as compatibility (A), confidentiality C, or reporting (D).

The best practice to prevent misuse of administrative privileges is to have administrators use a separate non-privileged account for routine tasks that do not require administrative rights. This reduces the risk of accidental changes or security breaches that could occur if the administrator’s highly privileged account were compromised or misused during daily operations.

References = This control measure is aligned with the principle of least privilege and is commonly recommended in cybersecurity frameworks. While I cannot cite the Cybersecurity Audit Manual directly, similar guidelines are often included in cybersecurity literature and standards, including those from ISACA1. For specific references, please consult the ISACA Cybersecurity Audit resources.

The “recover” function of the NIST cybersecurity framework is concerned with planning for resilience and timely repair of compromised capacities and service. This is because the recover function helps organizations to restore normal operations as quickly as possible after a cybersecurity incident, while also learning from the incident and improving their security posture. The other options are not part of the recover function, but rather belong to the identify (B), respond C, or protect (D) functions.

The control mechanism that is used to detect the unauthorized modification of key configuration settings is file integrity. File integrity is the property of ensuring that files are not altered or corrupted by unauthorized users or processes. File integrity can be monitored by using tools that compare the current state of files with a baseline or checksum and alert on any changes.

Security awareness training is MOST effective against social engineering threats. This is because social engineering is a type of attack that exploits human psychology and behavior tomanipulate or trick users into revealing sensitive or confidential information, or performing actions that compromise security. Security awareness training helps to educate users about the common types and techniques of social engineering attacks, such as phishing, vishing, baiting, etc., and how to recognize and avoid them. Security awareness training also helps to foster a culture of security within the organization and empower users to report any suspicious or malicious activities. The other options are not types of threats that security awareness training is most effective against, but rather types of attacks that exploit technical vulnerabilities or flaws in systems or applications, such as command injection (A), denial of service (B), or SQL injection (D).
