Zero trust security, on the other hand, can be implemented using software-defined micro-segmentation,
which provides organizations with complete visibility of all network traffic across bare-mental and hybrid
cloud environments. Essentially, healthcare organizations will be able to segment individual users,
applications, and workloads to drive down intent-based security policies to the host level.

This means that every single person or application which connects to the organizations network – be it
an employee, service provider, third-party vendor, or insurance partner – can be granted specific access
based on the security policies of the organization. Any attempt to access unauthorized data by a
prospective threat actor is immediately prevented and flagged, drastically reducing the attack surface.

To prevent employees from accessing sensitive data, healthcare organizations will be able to enforce
strict security policies that define and limit the access of individual employees. The visibility provided by
software-defined micro-segmentation will allow the security operators to record any deviation in behavior,
which can then be investigated and used to fine tune the security policy.

Cybercriminals have evolved to develop advanced malicious code that can circumvent perimeter security
and remain undetected. Attack forensics are also confirming that hackers are using sophisticated
mechanisms to exfiltrate data. Unless the healthcare industry is willing to take a serious look at the
inherent vulnerabilities of traditional network security systems, sensitive patient data will remain at risk.
