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 “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 primary purpose of a Security Operations Center (SOC) team is to continuously monitor and improve an organization’s security posture. They are responsible for the detection, analysis, and response to cybersecurity incidents, using a combination of technology solutions and a strong set of processes.

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).

 A web application firewall (WAF) is specifically designed to monitor, filter, and block HTTP traffic to and from a web application. It is different from other types of firewalls because it can filter the content of specific web applications. By inspecting HTTP traffic, a WAF can prevent attacks stemming from web application security flaws, such as SQL injection and cross-site scripting (XSS), file inclusion, and security misconfigurations.

References: The use of WAFs to block XSS and SQL injection attacks is well-documented in cybersecurity literature. They are recognized for their ability to perform a detailed inspection of HTTP traffic, applying rules to an HTTP conversation to cover a wide range of security issues, including XSS and SQL injection, which are not typically covered by other firewall types12.

Cybersecurity insurance typically covers direct and immediate losses due to data breaches and information security breaches. This often includes legal costs, credit monitoring costs, litigation costs (such as breach of privacy), and costs of regulatory investigations. Forensic investigation is a critical component of the response to a cyber incident, and the costs associated with it are generally covered under a cybersecurity insurance policy.

References: The information is supported by an article from ISACA titled “A Bird’s Eye View of Cyberinsurance Plans,” which outlines the general coverage provided by cyberinsurance plans, including forensic investigations1.

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).

DNS data exfiltration poses a significant threat to mobile computing mainly because it is challenging to differentiate between malicious activity and legitimate DNS traffic. Attackers can exploit this by embedding data within DNS queries and responses, which often go unnoticed because DNS traffic is generally allowed through firewalls and security systems without triggering alerts. This method of data theft can be particularly effective in mobile computing, where devices frequently switch networks and rely on DNS for connectivity.

References = ISACA’s resources on cybersecurity risks associated with DNS highlight the difficulty in detecting DNS data exfiltration due to its ability to blend in with normal traffic. This is further supported by industry resources that discuss the challenges in identifying and preventing such exfiltration techniques1234.

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 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.
