With the increase in threats targeting sensitive protected health information (PHI), organizations within and adjacent to healthcare must step up their data security controls. One way to do so is with the help of the guidelines listed in the NIST cybersecurity framework, which can be mapped to HIPAA’s data privacy safeguards. Read on to learn about this NIST to HIPAA crosswalk.
Guide to the NIST Cybersecurity Framework to HIPAA Crosswalk
The security standards in the NIST cybersecurity framework are widely implemented across security programs, regardless of industry—and can help improve the effectiveness of HIPAA safeguards. Our guide to the NIST cybersecurity framework to HIPAA crosswalk will cover:
- The importance of mapping the NIST security framework controls onto HIPAA ones
- A breakdown of the NIST CSF categories outlined in the crosswalk
Whether you are new to the NIST cybersecurity framework to HIPAA crosswalk or looking to optimize your cyberdefenses, working with a HIPAA compliance partner will streamline the process and help you remain compliant year-round.
NIST CSF to HIPAA Crosswalk – Streamlined Risk Management
As a robust risk management framework, NIST’s Framework for Improving Critical Infrastructure Cybersecurity—also called the NIST cybersecurity framework or CSF—provides standardized controls for managing cybersecurity risks, regardless of industry, organization size, or type of security infrastructure. However, optimizing risk management and tailoring security controls to the specific needs of each organization and industry is critical to mitigating cybersecurity risks.
In high-risk industries like healthcare, there are gaps in mapping the controls recommended by the NIST cybersecurity framework to the Health Insurance Portability and Accountability Act of 1996 (HIPAA) framework. To fully achieve the effectiveness of a healthcare data security program, organizations should tap into and implement the controls listed in both frameworks.
Organizations whose security program is fully compliant with HIPAA can leverage the NIST CSF to improve overall risk management, for PHI and other data that falls outside HIPAA’s scope.

The HIPAA Security Rule
Although HIPAA contains four primary Rules, the controls listed in the NIST cybersecurity framework to HIPAA crosswalk are adopted from the Security Rule. Under the HIPAA Security Rule, covered entities and business associates must safeguard PHI with three types of controls:
- Administrative safeguards
- Physical safeguards
- Technical safeguards
However, compliance with all the HIPAA Rules is critical to keeping PHI safe from various threats and vulnerabilities throughout the lifecycle of a security program. Mapping the controls outlined in the HIPAA Security Rule to those in the NIST cybersecurity framework will help enhance your security posture in the short and long term.
Breakdown of the NIST CSF Categories
The NIST CSF categories listed in the NIST cybersecurity framework to HIPAA crosswalk are spread across five functions:
- Identify (ID)
- Protect (PR)
- Detect (DE)
- Respond (RS)
- Recover (RC)
Healthcare and healthcare-adjacent organizations can leverage these risk management controls to identify gaps within their security programs. However, it is critical for these organizations to view the crosswalk simply as a reference, and not the sole baseline for regulatory compliance.
So, let’s review the various NIST CSF categories.
ID.AM – Asset Management
To achieve business purposes and manage security risks, HIPAA Security Rule-compliant organizations must:
- Conduct inventories of physical devices and software applications
- Map out data flows for internal and external communications
- Catalogue external information systems
- Prioritize asset risk management based on asset type, business value, or operational criticality
- Designate internal and external roles and responsibilities for cybersecurity management
Proper management of assets will help identify critical risks early on before they can develop into full-blown attacks and compromise data integrity.
ID.BE – Business Environment
When operating in any business environment, healthcare organizations and their partners must develop roles, responsibilities, and activities that effectively manage risk.
To meet or surpass the minimum healthcare risk management standards, organizations must:
- Identify and communicate their roles in the supply chain
- Establish and communicate mission priorities and objectives
- Outline critical dependencies necessary for service delivery
- Meet the resilience requirements to deliver essential services
Streamlining risk management in the healthcare business environment will help mitigate threats to PHI at rest and in transit across covered entities and their business associates.
ID.GV – Governance
When it comes to regulatory, legal, risk, and environmental governance, the NIST cybersecurity framework recommends that organizations implement:
- An organization-specific information security policy
- Processes to designate security roles and responsibilities both internally and externally

- Conducting forensics following incidents
- Categorizing incidents according to response plans
Proper analysis of security incidents is critical to supporting recovery activities and ensuring a robust response to the incidents.
RS.MI – Mitigation
Should a security event occur, it must be stopped from expanding to affect other assets and causing damage to them. The NIST cybersecurity framework to HIPAA crosswalk requires organizations in and adjacent to healthcare to contain and mitigate incidents as they unfold.
Any newly identified vulnerabilities must be documented as part of risk management efforts.
RS.IM – Improvements
As your organization learns from past security events, it must streamline its defenses in anticipation of future ones. Response plans must incorporate the lessons learned from previous incidents. Likewise, you must optimize security strategies and keep them up-to-date with the current demands of the healthcare industry’s IT landscape.
RC.RP – Recovery Planning
Recovery from security incidents boils down to ensuring that assets are restored to their original state as promptly as possible with the help of a recovery plan. For incident recovery to be effective, it must align with your organization’s security policy.
RC.IM – Improvements
Similarly, realizing improvements to incident recovery processes requires taking the learnings from previous security events and applying them to existing recovery plans. This process also requires updating recovery strategies to meet the demands of the current security environment.
RC.CO – Recovery Communications
Following a security incident, you will likely need to manage public relations and repair your reputation to maintain business relations. To streamline these communications, you will have to communicate with internal and external stakeholders, including management teams, to update them on your current recovery strategy.
