Understanding the Differences Between CIS v8, NIST, and ISO 27001

As technology continues to evolve and change nearly every day, many different regulations and frameworks have also emerged to help establish some order in the chaos. Some of the most recognised frameworks are the Center for Internet Security (CIS) Controls Version 8, the National Institute of Standards and Technology (NIST) frameworks, and ISO 27001:2022. Each of these frameworks offers unique approaches to cyber security, compliance, and risk management. In this article, we will explore the key differences between CIS v8 and these other frameworks to help you understand where these standards match, and where they differ.

Overview of CIS v8

CIS Version 8 (v8) is the latest iteration of the CIS Controls, which provides a prioritised set of actions designed to protect organisations from common cyber threats. The CIS framework is known for its practical, prescriptive approach, offering specific guidelines that businesses can implement to enhance their security posture. The controls are broken into three implementation groups, each based on their complexity, and resources available to an organisation, making it accessible for businesses of all sizes.

Key Features of CIS v8

Prescriptive Guidance: CIS v8 offers detailed recommendations for securing systems and networks, making it easier to accurately implement suggested changes.

Prioritised Controls: The framework emphasizes a priority-oriented approach, allowing organisations to focus on the most critical areas first.

Community-Driven: The CIS controls benefit from community input and real-world applicability, as they are developed by IT professionals to combat emerging threats.

Comparing CIS v8 with NIST

Approach to Security

NIST frameworks, such as the NIST Cybersecurity Framework (CSF), take a broader and more flexible approach compared to CIS. NIST focuses on overarching principles and risk management strategies rather than providing specific configurations. This allows businesses to tailor their security measures based on their unique risk profiles.

Compliance and Standards

NIST is often referenced in regulatory compliance contexts, such as HIPAA and PCI-DSS, making it a preferred choice for businesses needing to meet specific legal requirements. In contrast, while CIS provides valuable benchmarks, it may not cover all compliance needs comprehensively.

Flexibility vs. Prescriptiveness

The NIST frameworks allow for greater flexibility and customisation, enabling businesses to adapt their security measures according to their operational requirements. On the other hand, CIS v8 is more prescriptive, providing concrete steps that can be directly implemented.

Comparing CIS v8 with ISO 27001

Focus and Structure

ISO 27001 is an international standard that outlines requirements for an information security management system (ISMS). It emphasises a systematic approach to managing sensitive company information, ensuring adherence to the principles of confidentiality, integrity, and availability. In contrast, CIS v8 focuses specifically on actionable controls to mitigate both known and emerging cyber threats.

Certification vs. Implementation

ISO 27001 requires businesses to undergo a formal certification process, which can often be very resource-intensive. This certification demonstrates compliance with international standards, whereas CIS v8 does not have a formal certification process, as the controls are merely recommendations that can be implemented as additions to pre-existing security efforts.

Risk Management Approach

While both frameworks cover risk management, ISO 27001 takes a more comprehensive view by integrating risk assessment into its ISMS structure. CIS v8 focuses on specific controls that address immediate cyber security threats rather than an overarching, more general security approach.

Conclusion

Choosing the right cyber security framework depends on the specific needs, resources, and compliance requirements of a business. CIS v8 offers practical guidance with clear actions that can be quickly implemented, making it ideal for businesses looking for straightforward solutions to immediately enhance their security posture. In contrast, NIST provides a flexible approach suitable for those needing to align with regulatory standards, while ISO 27001 offers a comprehensive management solution for information security.
