Inquiries revolving around the exposed weaknesses and grouping related to identity

Network segmentation in healthcare organizations might be well-established, yet the question remains about identity segmentation.

In the dynamic and sensitive landscape of healthcare, where the protection of patient data is paramount, identity segmentation under a zero-trust security model has emerged as a crucial measure to secure access to electronic health records, medical devices, and applications.

According to a 2021 survey, an impressive 96 percent of healthcare providers utilize temporary staff each year, underscoring the need for robust security measures. Identity segmentation, a key component of zero-trust security, offers a solution by enforcing granular, identity-driven access controls that isolate users, devices, and workloads into smaller, tightly controlled segments.

This segmentation offers several benefits. Firstly, it limits access strictly to verified identities, both human and machine, ensuring that users and devices are authenticated and authorized with principles such as multi-factor authentication and role-based access.

Secondly, it restricts lateral movement within the network by micro-segmenting it into isolated zones where each segment has its own security policies. This containment prevents attackers from moving freely if one identity or device is compromised.

Thirdly, it incorporates continuous verification of both user identity and device posture, making sure access decisions take real-time contextual signals into account, which is critical for healthcare environments with sensitive patient data.

Lastly, it applies the least privilege principle via identity segmentation by granting minimum necessary access to healthcare resources based on verified identity attributes, reducing exposure of critical systems and protected health information (PHI).

In a world where healthcare providers must adhere to strict regulations around patient data under federal law, identity segmentation provides a layer of protection against insider threats, compromised credentials, or non-human identities like IoT and API accounts.

Furthermore, hybrid segmentation, a combination of hypervisor, agent-, and network-based segmentation used simultaneously, offers a versatile approach to securing healthcare environments. Hypervisor segmentation, for instance, uses overlay networks created by hypervisors to microsegment virtualized IT activities, while agent-based segmentation involves installing a software agent to monitor workload identities and attributes and enforce granular isolation per host or container.

However, it's crucial to manage user accounts effectively. A failure to provision, transition, and decommission these user accounts increases identity risk in healthcare. Proper management of user accounts is essential to maintain a secure and efficient healthcare environment.

In conclusion, identity segmentation serves as the backbone of zero-trust security in healthcare, transforming identity — both human and machine — into the new perimeter. It enables granular access management, isolates critical assets, and significantly reduces attack surfaces to safeguard patient data and healthcare operations.

Cybersecurity measures are essential in the healthcare sector, where sensitive data-and-cloud-computing activities are prevalent. By implementing identity segmentation under a zero-trust security model, technology can enforce granular access controls, limiting access strictly to verified identities, and isolating users, devices, and workloads.

In addition, the adoption of hybrid segmentation, a combination of hypervisor, agent-, and network-based segmentation, offers a versatile approach to securing healthcare environments, protecting patient data and healthcare operations.
