Mandating Zero Trust Architecture as a Condition of Cybersecurity Coverage

Mandating Zero Trust Architecture as a Condition of Cybersecurity Coverage

Joe Jambor

 

Abstract

The Change Healthcare breach in February 2024 exposed the protected health information of 190 million individuals and cost UnitedHealth Group nearly $3 billion. The breach occurred because two-factor authentication was turned off on a single portal, but was ultimately destructive because once the intruder was inside the system, there was little that could be done to stop them. This Article argues that cybersecurity insurers are uniquely positioned to prevent breaches like this one by driving adoption of Zero Trust Architecture (ZTA), the “never trust, always verify” framework codified in NIST Special Publication 800-207, by requiring its implementation as a condition of coverage. Despite its proven success rate, full ZTA adoption remains critically low, with only ten percent of large enterprises projected to reach a mature Zero Trust posture by the end of this year, as cost, institutional resistance, and legacy technology continue to impede progress. Market incentives alone have failed to move the needle. Drawing on four intersecting bodies of law; the contractual doctrine of conditions precedent in insurance agreements, federal sectoral cybersecurity regulatory frameworks including the FTC Safeguards Rule and HIPAA’s Security Rule, the state insurance regulatory architecture under the McCarran-Ferguson Act, and the rapidly evolving common law standard of reasonable cybersecurity, this Article establishes that insurer-mandated ZTA requirements are legally permissible, practically achievable through a phased implementation framework tailored to enterprises of all sizes, and essential to stabilizing the cyber insurance market while reducing legal liability for insureds.

Addressing the Vectors for Attack on Artificial Intelligence Systems Used in Clinical Healthcare through a Robust Regulatory Framework: A Survey

By Benjamin Clark

Introduction and Overview

Artificial intelligence has captivated the current interest of the general public and academics alike, bringing closer attention to previously unexplored aspects of these algorithms, such as how they have been implemented into critical infrastructure, ways they can be secured through technical defensive measures, and how they can best be regulated to reduce risk of harm. This paper will discuss vulnerabilities common to artificial intelligence systems used in clinical healthcare and how bad actors exploit them before weighing the merits of current regulatory frameworks proposed by the U.S. and other nations for how they address the cybersecurity threats of these systems.

Primarily, artificial intelligence systems used in clinical research and healthcare settings involve either machine learning or deep learning algorithms.[1] Machine learning algorithms automatically learn and improve themselves without needing to be specifically programmed for each intended function. [2] However, these algorithms require that input data be pre-labeled by programmers to train algorithms to associate input features and best predict the labels for output, which involves some degree of human intervention.[3] The presence of humans in this process is referred to as “supervised machine learning” and is most often observed in systems used for diagnostics and medical imaging, in which physicians set markers for specific diagnoses as the labels and algorithms are able to categorize an image as a diagnosis based off the image’s characteristics.[4] Similarly, deep learning is a subset of machine learning characterized by its “neural network” structure in which input data is transmitted through an algorithm through input, output, and “hidden” layers to identify patterns in data.[5] Deep learning algorithms differ from those that utilize machine learning in that they require no human intervention after being trained; instead, deep learning algorithms process unlabeled data by determining what input is most important to create its own labels.[6]
