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

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.
