Cybersecurity-Audit-Certificate Exam Dumps - Isaca Cybersecurity Audit Questions and Answers

Operating system rules can be configured to enforce password complexity requirements. These rules can specify the minimum length, complexity, and expiration of passwords. By setting these parameters, the operating system ensures that users create passwords that are difficult to guess or crack, thus enhancing security.

Multi-factor authentication (B) adds an additional layer of security but does not directly ensure the creation of complex passwords. Information security awareness © is crucial for educating users about the importance of complex passwords but does not enforce their creation. Biometrics (D) is an alternative form of authentication that may replace or supplement passwords but does not govern their complexity.

A limitation of intrusion detection systems (IDS) is that they cannot detect application-level vulnerabilities. An IDS is a tool that monitors network traffic or system activity and alerts on any suspicious or malicious events. However, an IDS cannot analyze the logic or functionality of applications and identify vulnerabilities such as SQL injection, cross-site scripting, or broken authentication.

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.

Elliptic curve cryptography (ECC) is a more efficient form of public key cryptography as it demands less computational power and offers more security per bit. ECC is based on the mathematical properties of elliptic curves, which are curves that have a special shape that makes them suitable for cryptography. ECC can achieve the same level of security as other public key algorithms with much smaller key sizes, which reduces storage and bandwidth requirements.

When passwords are used in key generation, they serve as a component of the encryption process. The strength of the encryption algorithm itself is not inherently affected by the use of passwords for key generation. Instead, the security of the encryption relies on the strength and complexity of the password, the key generation process, and the encryption algorithm’s resilience to attacks. A strong, complex password can contribute to a robust encryption key, thereby maintaining the intended strength of the encryption algorithm.

References: While I cannot provide direct references from the ISACA Cybersecurity Audit Manual, it is generally understood in cybersecurity practices that the encryption algorithm’s strength is determined by its design and resistance to cryptanalysis, not solely by the elements used in key generation. The use of passwords in key generation is a common practice and, when implemented correctly, does not diminish the algorithm’s strength. For specific references, please consult the ISACA Cybersecurity Audit resources or related study guides.

 Security frameworks are crucial in a cybersecurity strategy because they provide a structured approach to managing and mitigating risks. They help in integrating various cybersecurity activities and guiding them towards achieving the strategic objectives of the organization. By establishing a common language and systematic methodology, they ensure that all parts of the organization’s cybersecurity program are aligned and working cohesively.

References: The importance of security frameworks is highlighted in ISACA’s resources, which discuss how these frameworks support the organization’s missions and enhance the cybersecurity strategy by providing a clear structure for managing cybersecurity risks1.

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.

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

The CSA Cloud Controls Matrix (CCM) is a cybersecurity control framework specifically designed for cloud computing. It consists of a comprehensive set of control objectives that are structured across different domains covering all key aspects of cloud technology. One of the greatest benefits of using the CCM is its ability to map these controls to multiple industry-accepted security standards, regulations, and control frameworks. This mapping facilitates a streamlined approach to compliance and security assurance across various standards, making it an invaluable tool for organizations operating in the cloud.

References: The CCM’s advantage of providing a mapping to multiple control frameworks is highlighted by its alignment with other security standards and its role as a de-facto standard for cloud security assurance and compliance12. This multi-framework mapping capability enables organizations to document controls for multiple standards and regulations in one place, thereby simplifying the compliance process and ensuring a comprehensive security posture2.
