What is the recommended set of actions for cyber defense according to the CIS?

The recommended set of actions for cyber defense according to the Center for Internet Security (CIS) is the Critical Security Controls (CSCs). These controls provide a prioritized and actionable framework designed to improve an organization's cybersecurity posture. The CSCs are based on the most common attack patterns and vulnerabilities identified through real-world observations, thus addressing the areas where organizations are most likely to be compromised.

Implementing the CSCs helps entities establish effective security measures while optimizing resources, as they focus on the controls that yield the highest return on investment in terms of risk reduction. The framework assists organizations in understanding the crucial areas of focus to protect their systems effectively.

In contrast, other options such as Cyber Threat Intelligence (CTI), Network Security Protocols, and Vulnerability Assessment Guidelines are all valuable components within a comprehensive cybersecurity strategy. However, they do not specifically represent a structured set of recommended actions like the CSCs do. Cyber Threat Intelligence provides insights but lacks the framework for implementation that CSCs offer. Network Security Protocols help in establishing rules for communication but do not cover the broader spectrum of organizational cybersecurity practices. Similarly, Vulnerability Assessment Guidelines are essential for identifying weak points but do not constitute a proactive defense strategy like the CSCs.
