While HIPAA does not explicitly mention micro-segmentation, it is a security approach aligning with HIPAA’s security requirements by limiting access to patient data. By restricting access to only what a provider needs, it can greatly reduce the risk of unauthorized access.
What is micro-segmentation?
Micro-segmentation is a network security method that divides a larger network into smaller, isolated segments, each with its own access controls. The method creates distinct micro perimeters around specific applications, systems, or data sets within a network. It allows for more granular control over who and what can access each segment.
According to a review published in Sensors, “Micro-segmentation can prevent unapproved usage of crucial information or assets and limit the potential implications of a breach.” This is possible as micro-segmentation often also relies on limiting communication between segments to allow only necessary interactions and enforce strict rules around data flow and access.
HIPAA and micro-segmentation
Despite not being mentioned by HIPAA’s Security Rule, microsegmentation aligns with the core principles set by its Technical Safeguards. It supports the standards by dividing networks into isolated segments, and by limiting access and exposure to sensitive data like protected health information (PHI). The specific areas it applies include:
- Access controls: The standard requires limiting access to PHI, a requirement that micro-segmentation enforces by isolating data into secure zones.
- Audit controls: HIPAA requires organizations to log and monitor activities related to PHI access. Micro-segmentation allows for the precise auditing of PHI by logging traffic between network segments, offering improved visibility of who accessed specific data portions.
- Transmission security: Limiting access to narrow segments allows staff to limit the data shared. When accompanied by HIPAA compliant email, this ensures that information remains secure.
FAQs
Who does HIPAA apply to?
Covered entities like healthcare providers and their business associates.
What is the difference between required and addressable implementation?
Required implementations must be followed while addressable specifications allow some flexibility.
What are access controls?
Security measures that restrict who can view or use certain information within a system.
