Healthcare is evolving—and AI is leading the charge. AI-powered physician’s assistants now document clinical conversations, generate diagnostic suggestions, and recommend follow-ups. They save doctors countless hours, letting them spend more time with patients and less time with keyboards.
But with great efficiency comes new risk.
When healthcare networks deploy AI assistants that listen to doctor-patient appointments, transcribe the meeting, summarize diagnoses by confidence level, and link supporting resources. It is a triumph of operational value. Until the question arises: How do we know it’s secure?
The Stakes: More Than Just Compliance
In healthcare, the consequences of AI errors aren't just financial—they're clinical. This AI system touched Protected Health Information (PHI) daily. It influenced diagnoses. It impacts real patient care.
Healthcare networks needed to comply with HIPAA, the HITECH Act, FDA AI/ML guidance, ISO 27799, NIST AI RMF, and ISO/IEC 42001:2023. But it isn't enough to trust encryption and access controls on paper. You have to prove security—continuously.
AI Physician Assistant Threat Model
The AI assistant is at the center of doctor-patient interactions, connected to EHR databases, diagnosis suggestion engines, audit logs, and compliance reporting tools. Every one of these pathways could be a point of exposure, manipulation, or error. ZioSec tests them all.
How ZioSec Attacks AI in Healthcare
ZioSec doesn't assume the AI agent is safe—we attack it. Using real-world tactics mapped to MITRE ATLAS and OWASP MAESTRO, our offensive AI system stress-tests the AI physician assistant across every critical layer.
We inject adversarial phrasing to see if PHI could leak through unclear transcription. We manipulate clinical language to test diagnostic suggestion integrity. And we challenge audit logs with rare, ambiguous input patterns to surface blind spots. This isn't theory. It's execution.
Compliance vs. Offensive Testing (Healthcare AI)
Compliance checks might confirm encryption, access restrictions, and audit logs are in place. But only offensive testing proves whether those safeguards hold when the AI is pushed by realistic, adversarial conditions.
What We Find
AI agents are good—but not perfect. When confronted with ambiguous or noisy clinical conversations, the AI can incorrectly included identifiable information in the notes. Specific phrasing can artificially boost or deflate diagnostic confidence levels—potentially influencing clinical decisions. Rare edge cases cause logging gaps, meaning some AI actions aren't fully traceable.
Strength, Proof, and Confidence
Every issue can be swiftly addressed. PHI leakage pathways can be closed. Diagnostic outputs can be hardened against manipulation. Audit logging can be made airtight, even in rare conditions.
Better yet, the healthcare network doesn't just improve security—they document it. ZioSec’s offensive testing maps directly to HIPAA, HITECH, FDA, and ISO compliance requirements, providing audit-ready evidence that their AI system isn't just useful—it is safe.
And the testing isn't a one-off. It becames continuous. As AI models retrain, new features emerge, or clinical environments shift, ZioSec remains in place, running, testing, securing.
Continuous AI Security Lifecycle (Healthcare Context)
Adversarial testing, discovery, remediation, retesting. Healthcare AI isn't static—and neither is security. Continuous validation ensures that as your AI learns, your defenses evolve too.
In Healthcare, Security Is Patient Care
You've built AI to improve medicine. ZioSec helps you prove it's safe—day after day, update after update.
