Electronic Health Record (EHR) updates are typically planned around functionality. Healthcare organizations focus on improving workflows, enhancing interoperability, adding integrations, supporting regulatory requirements, and improving the clinician experience.

While these goals are important, every major EHR update also introduces cybersecurity considerations that cannot be overlooked.

Changes to an EHR environment can affect how data moves, how users authenticate, how third-party applications connect, and how sensitive patient information is accessed. Even well-planned updates can introduce security gaps that may not be immediately visible during implementation.

For healthcare organizations, cybersecurity validation should not begin after go-live. A penetration test conducted before or shortly after a major EHR update can help identify vulnerabilities, misconfigurations, and unintended access paths before they become operational, regulatory, or patient safety concerns.

Why EHR Updates Increase Cybersecurity Risk

Modern EHR systems are no longer isolated applications operating within a single network.

Today’s healthcare environments are highly interconnected ecosystems that support patient care through numerous integrations and data-sharing relationships.

Most EHR platforms communicate with:

• • Patient portals

• • Revenue cycle systems

• • Billing applications

• • Claims management platforms

• • Laboratories

• • Pharmacies

• • Medical imaging systems

• • Medical devices

• • Analytics platforms

• • Cloud applications

• • Third-party vendors

This connectivity improves clinical efficiency and supports coordinated patient care. However, every connection also represents a potential attack surface.

When organizations implement major EHR updates, they often introduce changes that affect multiple systems simultaneously.

How EHR Updates Expand the Attack Surface

A significant EHR update may include new integrations, modified workflows, updated authentication methods, and expanded user functionality.

Common changes include:

• • New APIs and interfaces

• • New vendor integrations

• • Changes to user permissions

• • Updated authentication workflows

• • New cloud-hosted services

• • Expanded patient portal capabilities

• • Additional data exchange pathways

• • Modified VPN, firewall, or remote access configurations

Individually, these changes may appear routine.

Collectively, they can create new opportunities for cybercriminals to gain access to sensitive systems and protected health information.

The Office of the National Coordinator for Health Information Technology (ONC) has emphasized that EHR safety depends not only on software functionality but also on implementation, configuration, maintenance, integration, APIs, and other technical components.

In other words, secure software can still become vulnerable if it is configured or deployed incorrectly.

Why Security Checklists Are Not Enough

Healthcare organizations often rely on security questionnaires, compliance reviews, configuration audits, and vulnerability scans to evaluate system changes.

These assessments are valuable, but they do not always reveal how an attacker might exploit weaknesses in the real world.

This is where penetration testing provides additional value.

A penetration test asks a different question:

“What could an attacker actually accomplish if they discovered a weakness?”

That distinction is critical.

A vulnerability scan may identify missing patches, outdated software, or exposed services.

A penetration test goes further by safely simulating real-world attack techniques to determine whether vulnerabilities can be exploited, whether access controls are functioning correctly, and whether sensitive systems can be reached.

What Is Penetration Testing?

Penetration testing is a controlled cybersecurity assessment designed to simulate the techniques used by real attackers.

Security professionals attempt to identify, validate, and safely exploit vulnerabilities to understand the potential impact on the organization.

The National Institute of Standards and Technology (NIST) identifies penetration testing as an important method for evaluating system security, validating controls, and identifying vulnerabilities that may not be apparent through traditional assessments.

For healthcare organizations, this practical validation is especially important because EHR systems support both patient privacy and continuity of care.

Why Penetration Testing Matters for Healthcare

Healthcare organizations face unique cybersecurity risks.

Unlike many industries, cyber incidents in healthcare can directly impact patient care, operational continuity, and regulatory compliance.

A security weakness introduced during an EHR update may lead to:

• • Unauthorized access to ePHI

• • HIPAA compliance violations

• • Operational disruptions

• • Clinical workflow interruptions

• • Data breaches

• • Financial losses

• • Reputational damage

These risks make security validation a critical component of any EHR modernization effort.

HIPAA Risk Analysis Must Reflect Current Reality

The HIPAA Security Rule requires covered entities and business associates to conduct an accurate and thorough assessment of potential risks and vulnerabilities affecting the confidentiality, integrity, and availability of electronic protected health information (ePHI).

This assessment cannot remain static.

Whenever the EHR environment changes, the organization’s risk profile changes as well.

A major EHR update may alter:

• • Where ePHI is stored

• • How ePHI is transmitted

• • Which users can access data

• • Which vendors interact with systems

• • Which applications exchange information

• • Which devices connect to the environment

If these changes are not tested, organizations may be relying on assumptions rather than evidence.

Penetration testing helps convert assumptions into measurable findings.

Three Questions Every Healthcare Organization Should Ask After an EHR Update

Every major EHR update should prompt leadership to ask three important questions:

What Changed?

Organizations must understand exactly what systems, integrations, workflows, and configurations were modified.

What New Access Paths Exist?

Every new connection introduces potential risk.

Healthcare organizations should identify and evaluate every new pathway into the environment.

How Do We Know It Is Secure?

This is the most important question.

Penetration testing provides evidence-based validation that security controls are functioning as intended.

EHR Updates Are Security Checkpoints

Healthcare organizations continue to invest heavily in digital transformation, interoperability, cloud services, patient engagement platforms, and modern EHR capabilities.

These innovations improve patient care and operational efficiency.

However, every major update also represents a security checkpoint.

Trust is not built solely by adopting better technology.

Trust is built by validating that technology before it becomes a risk.

A penetration test helps healthcare organizations identify weaknesses before cybercriminals do, strengthen HIPAA compliance, protect ePHI, and maintain confidence in critical clinical systems.

Because your next EHR update is more than a software milestone.

It is a cybersecurity milestone.

How Tempest Healthcare IT Helps Secure EHR Environments

Tempest Healthcare IT helps healthcare organizations strengthen cybersecurity before, during, and after major EHR changes.

Our healthcare-focused security services include:

• • Penetration Testing

• • Vulnerability Assessments

• • HIPAA Security Risk Assessments

• • Microsoft Defender Security Solutions

• • Microsoft Sentinel Monitoring

• • Incident Response Planning

• • Third-Party Risk Reviews

• • Security Architecture Assessments

We help healthcare organizations validate security controls, identify vulnerabilities, and reduce risk while supporting compliance and patient care objectives.

Secure Your Next EHR Update

Before your next EHR upgrade, migration, integration, or deployment, make cybersecurity part of the project plan.

A penetration test may reveal the vulnerabilities that compliance checklists and configuration reviews miss.

Because protecting patient information begins with verifying that your systems are secure before attackers have the opportunity to test them themselves.
