Which of the following is critical for influencing an organization's security culture?

High-level management support is critical for influencing an organization's security culture because leadership sets the tone and priorities for the organization. When management demonstrates a commitment to security through policies, resource allocation, and visible engagement in security initiatives, it creates an environment where employees understand the importance of following security protocols. This support encourages a proactive approach to security, where staff are more likely to adopt best practices and prioritize cybersecurity in their daily operations.

Additionally, high-level management involvement can lead to comprehensive training programs, clear communication about security expectations, and the establishment of a culture that values compliance and risk management. In such an environment, employees are motivated to adhere to security measures and recognize their role in maintaining the organization's overall security posture.

In contrast, while frequent system updates and cost-cutting measures can impact security, they do not inherently create or influence a cultural attitude towards security within an organization. The use of outdated technology clearly undermines security efforts, as it can expose the organization to vulnerabilities. Hence, high-level management support is paramount, as it directly shapes the organization's commitment to a robust security culture.
