Define "Critical Security Control."

A "Critical Security Control" refers to a set of best practices aimed at reducing the most prevalent and dangerous cyber threats facing organizations. This framework is designed to focus on actionable measures that organizations can implement to improve their security posture significantly. By concentrating on the most effective controls that address the most common vulnerabilities and attack vectors, organizations can prioritize their resources and efforts where they are likely to have the most significant impact.

This approach has been developed through extensive research and analysis of real-world incidents and provides a roadmap for organizations to follow in their efforts to secure sensitive data and systems effectively. The emphasis is on practical solutions that can lead to immediate improvements in security, making it a vital component of any organization's cybersecurity strategy.

The other options do not embody the essence of what a Critical Security Control is. The regulatory framework for data encryption pertains to compliance with laws and regulations rather than a proactive set of best practices. Establishing user roles and permissions relates more to access control mechanisms rather than broader cybersecurity measures. Lastly, an internal audit procedure focuses on compliance and verification rather than on the proactive implementation of security measures to defend against cyber threats.
