How to Perform a NIS 2 Gap Analysis: a Best Practices Checklist

Conducting a NIS 2 Directive gap analysis requires meticulous planning and execution. Consider these best practices when planning your NIS 2 gap analysis.

1. Understand the NIS 2 Directive Requirements
   Acquire a deep understanding of the directive’s requirements, ensuring that the gap analysis process is not only efficient but also comprehensive. This means scrutinising both technical specifications and broader organisational measures.
2. Define the Gap Analysis Objectives
   Establishing specific goals will provide a clearer framework for the gap analysis, guiding the assessment and facilitating the development of actionable insights. These objectives should be aligned with your broader compliance strategy.
3. Conduct a Thorough Gap Assessment
   Systematically review existing policies and procedures, assessing the effectiveness of technical controls and evaluating incident response mechanisms. The assessment should also consider your security risk management practices and the adequacy of resource allocation to critical cybersecurity areas.
4. Build a Dedicated Team
   Assemble a cross-functional team to ensure a comprehensive understanding of your existing security protocols, as well as the NIS 2 Directive requirements. Encouraging effective collaboration helps maintain focus on the analysis objectives and promotes the sharing of insights for a more effective and strategic plan to address identified deficiencies.
5. Gather Relevant Documentation and Data
   Collect existing security policies, incident response plans, risk assessment reports, and any other pertinent documents that reflect your current cybersecurity posture. Accurate and comprehensive data collection establishes a baseline against which your practices are measured and ensures the analysis is evidence-based, allowing for precise identification of gaps between current operations and NIS 2 Directive requirements.
6. Conduct a Risk Assessment
   A comprehensive risk assessment lets you evaluate the security and resilience of your network and information systems and identify the existing risks and vulnerabilities that could affect your compliance with the NIS 2 Directive. By thoroughly analysing the risk landscape, you can prioritise areas that require immediate attention and allocate resources effectively to address the most critical vulnerabilities.
7. Identify Current Security Measures
   Document all current security measures and protocols in place. Focus on understanding how these current security measures align with the NIS 2 Directive, as this will highlight specific compliance gaps that need addressing. Once these gaps are pinpointed, prioritise them based on the level of risk each poses to your organisation.
8. Evaluate Gaps in Compliance
   Analyse the gaps between the NIS 2 requirements and your organisation’s current security measures. This evaluation should highlight the specific areas where your organisation is not meeting the directive’s standards, giving clarity on what needs to be addressed.
9. Develop an Action Plan
   Based on the identified gaps, create a detailed action plan that outlines the steps and resources required to bridge these compliance gaps. This plan should be prioritised, addressing the most critical areas first to ensure effective compliance with the NIS 2 Directive. The action plan should include specific objectives, timelines, and responsible parties for each task.
10. Implement Remedial Measures
    Execute the action plan by implementing the necessary security measures and improvements. This may include adopting new technologies, updating policies, and providing training to staff to enhance compliance with the NIS 2 Directive. Implementation should be a coordinated effort involving all stakeholders to ensure seamless integration of new measures into existing systems.
11. Monitor and Review Progress
    Regularly monitor and review the progress of your compliance efforts. Continuous monitoring ensures that implemented measures are effective and helps identify any new gaps or areas that require further improvement. Utilising key performance indicators (KPIs) and metrics can aid in assessing the effectiveness of the implemented changes and ensuring alignment with the NIS 2 Directive.
12. Document and Report on Compliance
    Maintain detailed documentation of all compliance activities and improvements made. Documentation should capture the full scope of your compliance journey, detailing each step of the NIS 2 gap analysis process from initial assessment to implementation of remedial measures. Regularly update this documentation to reflect new developments, ensuring that it remains a reliable resource for internal reviews and external audits.
