Every day, businesses around the globe wrestle with the rapidly changing landscape of cybersecurity threats. Two well-known standards in the security industry, the National Institute of Standards and Technology (NIST) and the Center for Internet Security (CIS), provide frameworks to help address these threats. However, these two benchmarks often lead to the question: NIST or CIS, which is the better option for my organization? In this post, we will conduct a comparative analysis of NIST and CIS within the realm of cybersecurity.

The NIST, a non-regulatory agency of the U.S Department of Commerce, provides a framework for improving critical infrastructure cybersecurity, known as the Framework for Improving Critical Infrastructure Cybersecurity, commonly referred to as the NIST Cybersecurity Framework. This framework organizes cybersecurity around five functions: Identify, Protect, Detect, Respond, and Recover. It helps organizations understand and manage cybersecurity risk in relation to the business environment.

On the other hand, CIS is a non-profit entity that provides a set of 20 critical security controls. These controls are a recommended set of actions to mitigate the most pervasive attacks. They are designed to be implemented alongside other frameworks, such as NIST, and provide very tactical, technical, and actionable controls.

Detailed Comparison of NIST and CIS

Let's delve into the detailed comparison with respect to several key elements:

Scope

NIST's framework is designed to help organizations manage and reduce cybersecurity risk and focuses on three key areas: Cybersecurity, physical security, and personnel security. It's extensive and applies to all types of threats.

CIS, on the other hand, is more focused on known, specific cybersecurity threats and provides a set of controls to mitigate those threats. These controls are very tactical and technical in nature.

Applicability

The NIST Cybersecurity Framework can be used across sectors and organizations of any size and type. Its principles and best practices can be applied to any organization seeking to improve their cybersecurity posture.

The CIS controls, whilst still applicable across all sectors, tend to be more applicable to IT and security teams that manage systems and networks. The controls are particularly suitable for organizations with mature security programs.

Flexibility

NIST provides a framework that can be tailored to various industries and individual needs of an organization. It's flexible, and the implementation can be as comprehensive or as simple as needed.

CIS offers a more defined path with its list of controls, which means there's less room for customization. However, this also means it's easier to implement, perfect for organizations looking for a clear list of actionable steps.

Approach

NIST adheres to a risk-based approach, offering methods to identify potential problem areas and address them comprehensively.

CIS, by contrast, takes a threat-based approach, focusing on mitigating known threats and providing clear, actionable controls to prevent those threats.

Implementation Cost

NIST does not provide specific tools or solutions, hence the cost associated with implementation can vary based on the methods and solutions the organization opts for.

CIS, however, provides specific controls and sub-controls which can streamline the implementation process. Yet, achieving some controls could require significant investments.

Choosing Between NIST and CIS

In deciding between NIST and CIS, one must first evaluate organizational needs, maturity of the security program, available resources, organization size, and level of cyber threats.

NIST is comprehensive and flexible and is particularly suitable for organizations seeking a holistic approach toward cybersecurity. If flexible risk management and comprehensive implementation are top priorities, NIST might be for you.

If your organization is looking for a more tactical approach with specific controls, CIS would be the better fit. The defined list of controls is easier to adopt, especially if the organization wants a checklist of tasks to improve cybersecurity efforts.

Importantly, these two frameworks are not mutually exclusive and can be used in conjunction with one another to maximize cybersecurity effectiveness.

In conclusion

In conclusion, both NIST and CIS offer valuable frameworks for enhancing cybersecurity. NIST's broader, risk-based approach vs CIS's more tactical, threat-based approach offers different benefits. The choice depends largely on your organizational needs, resources, and current security state. While each framework has its strength, they can also be used together, providing a comprehensive and powerful method to handle cybersecurity threats. Although the 'NIST vs CIS' debate persists, the end goal is the same: implementing a strategic approach to cybersecurity threats and protecting your organization's critical information.
