NIS2 vs CIS Controls v8: Complete Mapping for CISOs

As the deadline for NIS2 compliance approaches, many organizations are evaluating their existing cybersecurity frameworks to ensure alignment with the new directive. For those already implementing CIS Controls v8, there is a significant overlap with NIS2 requirements, providing a head start. This article offers a detailed mapping between NIS2 Article 21 measures and CIS Controls v8, highlights areas where CIS Controls fall short, and prioritizes remediation efforts for organizations aiming to meet NIS2 standards.

The Overlap Between CIS Controls v8 and NIS2

Both CIS Controls v8 and NIS2 are risk-based frameworks designed to enhance cybersecurity resilience. They share a common goal of reducing risk through structured, prioritized actions. CIS Controls v8 is a set of best practices developed to guide organizations in protecting their systems and data from cyber threats. NIS2, on the other hand, is a directive aimed at improving the cybersecurity posture of essential and important entities within the EU.

Risk-Based Approach

Both frameworks emphasize a risk-based approach to cybersecurity, focusing on identifying and mitigating risks before they can be exploited. This alignment makes it easier for organizations using CIS Controls v8 to adapt to NIS2 requirements, as many foundational principles are already in place.

Common Objectives

CIS Controls v8 and NIS2 share common objectives such as ensuring the confidentiality, integrity, and availability of information systems. They both advocate for regular risk assessments, continuous monitoring, and incident response capabilities.

Mapping NIS2 Article 21 Measures to CIS Implementation Groups

NIS2 Article 21 outlines specific security measures that entities must implement. These measures can be mapped to the CIS Controls v8 Implementation Groups (IGs), which categorize controls based on organizational size and risk profile.

Security Measures and IGs

1. 1Risk Analysis and Information System Security Policies: Aligns with CIS Control 1 (Inventory and Control of Enterprise Assets) and Control 2 (Inventory and Control of Software Assets).

1. 1Incident Handling: Corresponds to CIS Control 17 (Incident Response Management).

1. 1Supply Chain Security: Partially covered by CIS Control 15 (Service Provider Management).

1. 1Security in Network and Information Systems: Relates to CIS Control 12 (Network Infrastructure Management).

1. 1Access Control Policies: Matches CIS Control 5 (Account Management) and Control 6 (Access Control Management).

Gaps in CIS Coverage for NIS2

While CIS Controls v8 provides a solid foundation, there are specific areas where it does not fully cover NIS2 requirements. These gaps include supply chain security, incident reporting, and governance.

Supply Chain Security

NIS2 places a strong emphasis on securing the supply chain, which is only partially addressed by CIS Controls. Organizations must enhance their supply chain risk management practices to meet NIS2 standards.

Incident Reporting

NIS2 requires timely incident reporting to national authorities, a requirement not explicitly covered by CIS Controls. Organizations need to establish clear protocols for incident notification in compliance with NIS2.

Governance and Accountability

NIS2 introduces governance requirements, including the need for board-level accountability and oversight, which are not a focus of CIS Controls v8.

NIS2 Specifics Not Covered by CIS

There are several NIS2-specific requirements that are not addressed by CIS Controls v8, necessitating additional measures for compliance.

Board Accountability

NIS2 mandates that boards of directors are accountable for cybersecurity, requiring them to be informed and involved in cybersecurity strategy and risk management.

24-Hour Incident Reporting

Under NIS2, incidents that significantly impact services must be reported to the relevant national competent authority (NCA) within 24 hours. This rapid reporting requirement is not part of CIS Controls.

NCA Registration

Entities must register with their national competent authority, a procedural requirement absent in CIS Controls.

Remediation Priority List for CIS IG2/IG3 Organizations

For organizations operating at CIS Implementation Group 2 or 3, prioritizing remediation efforts is crucial to achieve NIS2 compliance.

Immediate Actions

1. 1Enhance Supply Chain Security: Develop comprehensive supply chain risk management strategies.

1. 1Establish Incident Reporting Protocols: Implement procedures for rapid incident reporting to NCAs.

1. 1Strengthen Governance: Engage the board in cybersecurity oversight and ensure accountability.

Medium-Term Actions

1. 1Conduct Regular Risk Assessments: Align risk assessments with NIS2 requirements to identify and mitigate risks effectively.

1. 1Improve Network and Information System Security: Invest in advanced security measures for network and information systems.

Self-Assessment: NIS2 Readiness Score from CIS Controls Baseline

Organizations can perform a self-assessment to evaluate their readiness for NIS2 compliance using their existing CIS Controls baseline.

Readiness Evaluation

1. 1Evaluate Current Controls: Assess the implementation of CIS Controls against NIS2 requirements.

1. 1Identify Gaps: Determine areas where additional measures are needed for NIS2 compliance.

1. 1Develop an Action Plan: Create a roadmap to address identified gaps and align with NIS2 standards.
