Creating Your NIST SP 800-53 Control Mapping Spreadsheet

Creating a control mapping spreadsheet involves several key steps. This process requires a meticulous approach to ensure that all aspects of an organization's security framework are aligned with NIST standards. The following steps provide a detailed guide to effectively create and use a control mapping spreadsheet.

Step 1: Gather Existing Security Controls

Start by compiling a list of all current security controls your organization has in place. This list will serve as the baseline for your mapping process. Having a comprehensive understanding of your existing controls is crucial, as it provides the foundation upon which you will build your mapping efforts.

Ensure that this list includes all technical, administrative, and physical controls, as well as any policies and procedures that are part of your security framework. This comprehensive approach will help you capture the full scope of your current security posture.

Step 2: Understand NIST SP 800-53 Controls

Familiarize yourself with the controls outlined in NIST SP 800-53. The publication is divided into families, such as access control, audit and accountability, and incident response, each containing specific controls. Understanding these controls in detail is essential to effectively map them to your existing security measures.

Take the time to review each control family and identify the specific controls that are relevant to your organization. This will help you focus your efforts on those areas that are most critical to your security objectives.

Step 3: Map Existing Controls to NIST Standards

Using your compiled list, begin mapping each existing control to the corresponding NIST SP 800-53 control. This process will help you identify any overlaps or gaps. Mapping is an iterative process that may require multiple reviews to ensure accuracy and completeness.

During this step, it is important to document any discrepancies or areas where controls do not fully align with NIST standards. This documentation will be invaluable during the gap analysis phase.

Step 4: Conduct a Gap Analysis

Once mapping is complete, conduct a gap analysis to identify where your current controls fall short of NIST standards. This analysis will highlight areas that require additional attention and resources. A thorough gap analysis is essential to prioritize your efforts and ensure that you address the most critical deficiencies first.

Consider using qualitative and quantitative measures to assess the significance of each gap. This will help you develop a more informed and strategic approach to remediation.

Step 5: Develop an Action Plan

Based on your gap analysis, develop an action plan to address any deficiencies. Prioritize controls based on risk and impact to ensure critical areas are addressed first. An effective action plan should include specific steps, responsible parties, and timelines for implementation.

Engage stakeholders from across the organization to ensure that your action plan is realistic and achievable. Their input can provide valuable insights and help secure the necessary support and resources for successful implementation.

Step 6: Review and Update Regularly

Cybersecurity is a dynamic field, and the threat landscape is constantly changing. Regularly review and update your control mapping spreadsheet to ensure it remains relevant and effective. Set a schedule for periodic reviews and updates, and integrate feedback from security incidents and audits to continuously improve your security posture.

In addition to regular reviews, consider conducting ad-hoc updates in response to significant changes in the threat landscape or organizational priorities. This proactive approach will help you stay ahead of emerging threats and maintain compliance with evolving standards.
