Healthcare IT Security: Best Practices, Compliance, and Risk Assessment

Healthcare organizations have private and confidential patient information, EHRs, and medical devices that require security against any cyberattack. With the advent of digitalization in healthcare, it is essential for the safety of patients’ information, regulatory compliance, and continuous delivery of patient care that healthcare IT security must be ensured.

However, IT security goes beyond data breaches. An IT security incident can lead to disruption of clinical operations, breach of sensitive information, and loss of trust in patients.

Also, an organization must be ready to meet the challenges of compliance and the threat that comes from third parties.

It is essential to mention a proactive IT security approach in terms of conducting regular assessments, adequate access control, monitoring, and planning for incidents.

Cybersecurity Performance Goals set by the U.S. Department of Health and Human Services will assist in determining required measures.

This guide will cover best practices in healthcare IT security, compliance issues, risks and threats, and assessment processes.

Understanding the Role of IT Security in Modern Healthcare Systems

Healthcare IT security protects healthcare systems, EHR & EMR systems, hospital networks, connected medical devices, cloud environments, and applications from cyberattacks, data breaches, and unauthorized access. It helps maintain the confidentiality, integrity, and availability of patient information while supporting safe, reliable clinical operations.

As healthcare organizations increasingly rely on digital systems to manage patient records, deliver services, and exchange medical information, security becomes essential to protecting sensitive data and maintaining access to critical healthcare services.

Key Functions of Cybersecurity in Healthcare

1. Patient Data Protection

Electronic health records contain confidential information, including medical histories, diagnoses, treatment details, and insurance records. Appropriate security measures help prevent unauthorized access, disclosure, and misuse of this information.

2. Clinical Operations and Service Continuity

Cyberattacks and system failures can disrupt hospital networks, electronic records, and clinical applications. Secure infrastructure, tested backups, and recovery plans help healthcare organizations restore essential services and minimize interruptions to patient care.

3. Regulatory Compliance Support

Healthcare organizations must comply with applicable data protection and security requirements. Risk assessments, documented policies, and appropriate safeguards help identify compliance gaps and protect electronic protected health information (ePHI).

4. Cybersecurity Risk Reduction

Threats such as ransomware, phishing, credential theft, and unauthorized access can compromise patient data and disrupt healthcare operations. Security monitoring, timely software updates, access controls, and workforce training help reduce exposure to these threats.

5. Connected Medical Device Protection

Connected medical devices can introduce vulnerabilities into healthcare networks. Device inventories, security updates, network segmentation, and ongoing monitoring help reduce these risks while accounting for clinical safety requirements.

6. Patient Trust and Confidentiality

Patients expect healthcare providers to handle their personal and medical information responsibly. Consistent security practices help protect confidentiality and maintain confidence in digital healthcare services.

Common Healthcare IT Security Threats and Vulnerabilities

Healthcare organizations face cybersecurity threats that can expose patient information, disrupt clinical workflows, and affect access to essential systems. Understanding how these threats occur helps healthcare providers identify vulnerabilities and choose appropriate safeguards.

1. Ransomware and Phishing Attacks

Using misleading emails, cybercriminals can convince staff members of the healthcare organization to open a harmful attachment or share their login data. As a result, ransomware might encrypt the system.

Example: An employee of a hospital receives an email that is supposed to be from one of the hospital's suppliers. As soon as the attachment is opened, the employee unwittingly allows the hackers to infect the hospital’s network with malware that makes it impossible for the hospital to access patient data.

How to prevent it: Filtering e-mails, MFA, employee training, and proper backups are key in preventing such attacks.

2. Data Breach and Unauthorized Access to Patient Data

Weak passwords, credential theft, and too many user rights will enable someone to gain unauthorized access to patient data.

Example: A previous employee has retained their account even after leaving the healthcare organization. The credentials can be used to gain access to patient data.

How to prevent it: Role-based access control and regular reviews of users' access rights will help prevent such attacks.

3. Insider Threats and Human Error

The staff in healthcare institutions deal with a lot of confidential information. The accidental disclosure of this information, improper file sharing, and the misuse of access rights by the person can violate the privacy of patients.

Example: The staff in the healthcare organization mistakenly sends a report regarding the health conditions of a patient through an email as he mistakenly chooses the wrong person from the contact list.

How to prevent it: Educate the staff about proper handling of the information and install proper security measures in email systems. 

4. Vulnerable Medical Devices and Outdated Applications

Healthcare devices and applications are used in some cases that may not have up-to-date software installed in them. Such software vulnerabilities can act as vulnerabilities for entry into the network of the hospital.

Example: An old diagnostic workstation installed in the hospital does not receive any kind of security updates. In case the workstation is compromised, the attacker may try to access other networked devices through this station.

How to prevent it: Keep track of all the devices that are connected, install all security patches that are applicable, and isolate vulnerable devices from others.

5. Third-Party and Cloud Security Risks

Healthcare institutions rely on external vendors to provide them with software, data storage solutions, billing services, and more. Inadequate vendor security and improper cloud settings may lead to the exposure of sensitive information.

Example: A healthcare organization keeps its patients' files in cloud storage with too broad access settings. These files will be available to unauthorized personnel until the configuration is changed.

How to prevent it: Find a reliable healthcare software development partner, evaluate vendor security measures, restrict third-party access, configure cloud permissions correctly, and monitor systems for suspicious activity.

Healthcare IT Security Compliance Requirements

Healthcare institutions have to protect ePHI, implement proper security controls, and adhere to all relevant data protection regulations. Knowledge about the compliance of healthcare IT security will help providers to avoid security risks and fulfill their legal responsibilities.

Understanding Applicable Healthcare Data Protection Regulations and Security Standards

Healthcare IT security compliance covers both mandatory and optional requirements and standards of security. It depends on each particular institution and its activities.

• HIPAA Security Rule: Establishes administrative, physical, and technical safeguard requirements to protect the confidentiality, integrity, and availability of electronic protected health information. It applies to HIPAA-covered entities and business associates.
• HIPAA Privacy Rule: Governs how covered entities may use and disclose protected health information (PHI) and establishes requirements for protecting patient privacy.
• HIPAA Breach Notification Rule: Requires covered entities and business associates to follow applicable notification requirements when a breach of unsecured PHI occurs. Not every security incident automatically qualifies as a reportable breach.
• HITECH Act: Strengthened HIPAA enforcement and breach notification provisions and supported the adoption of electronic health records.
• NIST Cybersecurity Framework (CSF) 2.0: Provides voluntary guidance for managing cybersecurity risks through six functions: Govern, Identify, Protect, Detect, Respond, and Recover.
• HHS Healthcare and Public Health Cybersecurity Performance Goals: Offer voluntary, healthcare-focused cybersecurity practices to help organizations prioritize safeguards against common threats.

Healthcare institutions should distinguish current legal obligations from voluntary recommendations. For example, the existing HIPAA Security Rule remains in effect while proposed updates are considered through the rulemaking process. Organizations should verify the current status of regulatory changes before updating their compliance programs.

Implement Appropriate Security Controls

Healthcare providers should select security controls based on their risk analysis, applicable legal requirements, and operational needs. Common controls include:

• Access controls: Restrict access to patient records and clinical systems according to job responsibilities, using unique user accounts and role-based permissions.
• Multi-factor authentication (MFA): Add another verification step to help prevent unauthorized access, particularly for remote access, privileged accounts, and systems containing sensitive information.
• Encryption: Protect ePHI in transit and at rest where appropriate, considering applicable requirements, system capabilities, and documented risks.
• Backup and recovery: Maintain protected backups and test recovery procedures to support continuity of care after ransomware attacks, system failures, or other disruptions.
• Security monitoring: Review system activity, investigate suspicious behavior, and establish procedures for responding to potential security incidents.
• Workforce training: Teach staff how to recognize phishing, handle patient information securely, and report suspected incidents.

These controls should form part of a documented security program rather than operate as isolated measures. MFA and encryption are widely recommended safeguards, but organizations should avoid assuming that the current HIPAA Security Rule explicitly mandates every specific implementation method in all circumstances.

Common Healthcare IT Security Compliance Challenges

Healthcare institutions could face issues associated with meeting the compliance requirements while operating their clinical services, implementing innovations, and working under constraints on available resources.

• Legacy technology: Old software products and medical equipment could be lacking in terms of having adequate security capabilities or could be supported by vendors to a limited extent.
• Resource constraints: Small organizations may find it hard to provide adequate expertise in the field of security management, monitoring of systems, and performing risk assessments regularly.
• Third parties: Organizations should consider that a third party who will access, maintain, or process ePHI could pose an additional risk. A BAA is required in cases where the vendor relationship fulfills the conditions of a business associate in accordance with HIPAA.
• Changes in threat and regulations: Companies should perform a security program review considering the change in threat scenario and technology being used.
• Incomplete risk assessment: The practice of vulnerability scanning does not complete the requirement for performing a security risk assessment.

Essential Healthcare IT Security Best Practices

Healthcare institutions require an organized strategy to safeguard patients' data, ensure system security in clinics, and decrease cybersecurity threats. Secure healthcare IT is possible through a combination of technological means, education of the personnel, and conducting regular risk assessments.

Below you will find the best practices that will allow healthcare providers to increase the level of security of their IT infrastructure without disturbing clinical processes.

1. Role-Based Access Control and Multi-Factor Authentication

Not all employees require access to the information in every patient's file or in every healthcare application. It is necessary to introduce role-based access control (RBAC), which will enable doctors, nurses, administrative employees, and IT specialists to access only the information that is needed.

An additional protective measure is multi-factor authentication (MFA). This method requires users to authenticate their identity via one more means. It is vital to use MFA for remote logins, privileged accounts, and accessing patient information.

How to implement it:

• Assign permissions according to job responsibilities and the principle of least privilege.
• Require MFA for remote connections and privileged accounts.
• Review user permissions regularly and revoke access promptly when employees leave or change roles.
• Monitor unusual login attempts and unauthorized access patterns.

2. Encrypt Sensitive Healthcare Data

Healthcare organizations store and transfer confidential data using such technologies as EHRs, patient portals, billing systems, and other connected software. The use of encryption technologies will help you to keep your confidential data secure in case of loss of storage devices, system attacks, and interception of data being transferred.

Implement proper data encryption at rest and in transit. Management of encryption keys and their limitation should also be taken into account by the healthcare organization.

How to implement it:

• Implement proper protocols of encryption for databases, backups, endpoints, and data transfers.
• Create a secure connection between your GDPR-compliant healthcare software and any external entities.
• Store encryption keys separately and restrict access to them.
• Review your encryption configuration and fix all systems that cannot ensure the necessary level of protection.
• Encryption should be a part of the security strategy. It does not substitute other measures aimed at protection of confidential information.

3. Keep Systems and Medical Devices Updated

The vulnerabilities and outdated software might be exploited by hackers to attack the healthcare facility infrastructure. It becomes even more complicated if the software and equipment used at the facility are already old and are involved in carrying out the business processes but cannot be shut down immediately.

Create a patch management plan that would assist you in determining what needs to be updated, what kind of vulnerabilities exist in those systems, and how updates should be carried out.

If it is not possible to install a patch on the medical device, cooperate with the vendor to find other means of protecting the device.

How to implement it:

• Keep track of all the operating systems, applications, servers, and medical devices.
• Stay informed about the security notifications of vendors and prioritize the patches based on the vulnerabilities being exploited now.
• Test all the updates on the systems supporting the critical clinical processes.
• Control the usage of unsupported devices on your network.
• Having the process described above will help your healthcare organization to manage the vulnerabilities efficiently without disrupting work.

4. Secure Healthcare Networks and Endpoints

The hospital’s networks interconnect workstations, servers, diagnostic devices, medical devices, administrative systems, and cloud computing. If a malicious user gains access to any of the systems, the lack of network security will enable the attacker to propagate the risk to other critical resources.

Deploy firewalls, EDR solutions, and segment networks in order to raise the level of security.

Isolating medical devices, guest Wi-Fi, administrative systems, and other sensitive systems from one another will protect against lateral spread in case of infection of an endpoint.

How to implement it:

• Segmentation should be applied to different networks based on the intended purpose, level of sensitivity, and necessary connectivity of the respective system.
• Use endpoint protection programs for all such systems that are possible.
• Disable any ports, services, and communication channels that are no longer used in the system.
• Monitor regularly your firewall configuration and access to your network regularly.
• Analyze the network traffic for any suspicious activity that may take place between the systems in question.

This will ensure that the effect of the attack is reduced on the attacked endpoint and visibility is increased within the IT infrastructure of the healthcare organization.

5. Create Backups for Important Data and Recovery Mechanisms

Certain events like ransomware attacks, mistakes made by individuals, hardware failures, etc. could cause critical data to be unavailable in the healthcare organization. Having backups would make it possible to retrieve critical data without depending solely on the compromised environment.

The healthcare organization must ensure that backups for all critical data and configurations are made and stored at an accessible location that is secure and inaccessible to regular users. The backups should be secured in a way that prevents them from being modified or deleted by any unauthorized users.

How to implement it:

• Identify the critical systems and determine their RTO and RPO.
• Take backups according to the frequency of change in data and the tolerable loss of data.
• Store the backups of critical systems separately.
• Test and ensure successful restoration of data and verify its usability.
• Establish restoration priorities based on systems used for clinical work.
• An effective backup plan allows restoration of the organization's data and functions in an acceptable amount of time.

6. Train Healthcare Staff to Recognize Security Threats

Staff members can be compromised through phishing, fraudulent login screens, malicious email attachments, and social engineering. The compromise of even one account might lead to the exposure of confidential data or give attackers access to the company’s internal network.

The security training should vary according to the responsibilities of staff members. Some of them may need to receive training on patient information protection, and others may need more training on access management, detection of suspicious behavior, and reporting of security incidents.

How to implement it:

• Make sure that training on phishing, passwords, and information security is performed regularly.
• Use realistic simulations to train staff in recognizing phishing emails.
• Make sure that there is a convenient method for reporting security incidents, including phishing.
• Train staff in how to deal with patient information via emails, telephone calls, and remote access.
• Conduct training regarding new threats and internal policies.
• The most effective training happens when employees are trained to promptly report their mistakes and any kind of suspicious activity without hesitation for fear of being punished.

7. Monitoring and Getting Ready to Respond to Security Incidents

Despite all preventative efforts, there is still no way to prevent everything through prevention measures. This will allow the health care professionals to identify any types of suspicious behavior and act upon it accordingly.

The monitoring process must cover the critical systems, accounts, endpoints, and network activity. An incident response plan has to be developed and include descriptions of personnel accountable for alert investigation, decision-making during operations, and recovery of critical services.

How to implement it:

• Collect and analyze security logs of critical systems and applications.
• Set up alerts for suspicious logins, privilege changes, and data transfers.
• Develop the procedures for investigating and recovering from the security incident.
• Develop escalation and communication procedures for IT, clinical leadership, and other stakeholders.
• Hold incident response drills and improve the procedure according to results.

Health care organizations can use HHS Cybersecurity Performance Goals to develop their practical countermeasures against common threats.

8. Assess Third-Party Risks and Manage Vendor Access

Healthcare providers often depend on external vendors for cloud hosting, EHR platforms, billing, IT support, and other technology services. These relationships can introduce security risks when third parties have access to sensitive information or critical systems.

Before engaging a vendor, evaluate its security practices and determine whether it will create, receive, maintain, or transmit protected health information. Where HIPAA business associate requirements apply, appropriate agreements and safeguards are essential.

How to implement it:

• Evaluate vendor security controls before granting access to healthcare systems or sensitive data.
• Establish appropriate contractual security responsibilities and business associate agreements when required.
• Limit vendor permissions to the systems and information necessary for their work.
• Review third-party access periodically and remove unnecessary accounts promptly.
• Include critical vendors in incident response and business continuity planning.
• Third-party risk management should continue throughout the relationship, not end when a contract is signed.

Mapping Healthcare IT Security Practices to Risks and Evidence

Healthcare organizations should verify that security controls are working, not simply confirm that policies and tools exist. Mapping each best practice to its associated risks and supporting evidence helps security teams identify gaps, prioritize corrective actions, and track improvements over time.

The evidence should demonstrate whether a control is effective in the organization's actual environment. For example, successful backup jobs do not establish that critical systems can be restored; recovery tests provide stronger evidence of readiness. Similarly, a network segmentation diagram should be supported by configuration reviews or testing to confirm that the intended restrictions work.

Healthcare security teams should document identified gaps, assign remediation owners, set deadlines according to risk, and verify that corrective actions are effective. This approach makes security reviews more actionable and helps organizations demonstrate how they manage risks to patient information and clinical operations.

How to Measure Healthcare IT Security Effectiveness

Implementing healthcare IT security controls is only part of an effective security program. Healthcare organizations also need to evaluate whether those controls reduce risk, protect patient information, and support the availability of critical clinical systems.

Security teams can use key performance indicators (KPIs) and operational metrics to track progress, identify weaknesses, and prioritize improvements. The metrics should reflect the organization's risk assessment, technology environment, clinical requirements, and available resources.

How to Use These Metrics

Use the following steps to turn security metrics into actionable improvements:

• Establish a baseline: Record current performance for each metric, such as overdue critical vulnerabilities, MFA coverage, and incident containment time.
• Set targets and review intervals: Define acceptable performance levels based on organizational risk, clinical requirements, and recovery needs. Assign a review frequency to each metric.
• Assign ownership: Identify the team or individual responsible for monitoring each metric, investigating gaps, and reporting progress.
• Investigate recurring gaps: If critical vulnerabilities repeatedly miss remediation deadlines, determine whether the cause is limited staffing, unclear ownership, legacy systems, or clinical constraints.
• Take corrective action: Assign remediation tasks, adjust maintenance schedules, implement compensating safeguards, or escalate unresolved risks for formal review.
• Validate the results: Check whether corrective actions improve security outcomes. For example, successful backup jobs are not sufficient evidence of recoverability; restoration tests should verify that systems meet documented recovery time objectives (RTOs) and recovery point objectives (RPOs).

High MFA coverage does not automatically mean access is appropriately controlled, and completed security training does not necessarily demonstrate that employees can recognize threats.

HHS's voluntary goals can help organizations prioritize high-impact safeguards, including vulnerability management, multifactor authentication, incident preparedness, and vendor risk management.

These are suggested operational measures, not universal regulatory thresholds. Set targets according to the organization's risk profile, size, clinical environment, applicable obligations, and recovery needs.

How to Conduct an IT Security Assessment for Healthcare

A healthcare IT security assessment helps organizations identify vulnerabilities, evaluate existing safeguards, and understand where improvements are needed. It examines the systems that store or process patient information, the people who access them, and the potential impact of a security incident on clinical operations.

For US healthcare organizations subject to HIPAA, risk analysis is a required part of the Security Rule's administrative safeguards. The HHS guidance on risk analysis explains how organizations can identify and assess risks to electronic protected health information (ePHI).

A structured assessment typically involves five steps.

1. Identify Critical Systems and Sensitive Data

Start by identifying the systems, applications, and devices that support healthcare operations. These may include electronic health records (EHRs), patient portals, medical billing platforms, hospital networks, cloud applications, and connected medical devices.

Next, determine what sensitive information each system stores or processes, where that information moves, and who can access it. This helps establish which assets require the strongest protection.

Key actions include:

• Create an inventory of critical systems, applications, and connected devices.
• Identify where patient records and other sensitive information are stored.
• Map how data moves between internal systems and third-party services.
• Document system owners, business dependencies, and vendor access.

2. Evaluate Vulnerabilities and Existing Security Controls

Once critical assets are identified, examine them for weaknesses that could expose patient information or disrupt healthcare services. These may include outdated software, insecure configurations, unpatched vulnerabilities, weak network boundaries, or inadequate backup procedures.

Review existing security controls to determine whether they are implemented correctly and working as intended. Vulnerability scans can help identify technical weaknesses, while configuration reviews and penetration testing may provide additional insight where appropriate.

Key actions include:

• Scan systems for known vulnerabilities and missing security updates.
• Review firewall rules, endpoint protection, encryption, and network configurations.
• Check whether backups can be restored successfully.
• Evaluate monitoring and incident response capabilities.
• Document identified weaknesses and the safeguards already in place.

Testing should be planned carefully around clinical operations, particularly when medical devices or systems supporting patient care are involved.

3. Review Access Permissions and Compliance Gaps

Access reviews help determine whether employees, contractors, and third-party vendors have appropriate permissions. Excessive access can expose patient information unnecessarily and increase the potential impact of compromised accounts.

The assessment should also compare existing policies and safeguards against applicable HIPAA requirements. This helps identify areas where documentation, technical controls, or operational procedures may need improvement.

Key actions include:

• Review user accounts, administrator privileges, and remote access permissions.
• Confirm that access rights reflect current job responsibilities.
• Check MFA implementation and account deactivation procedures.
• Review security policies, risk analysis documentation, and incident response procedures.
• Identify gaps between existing safeguards and applicable compliance requirements.

A compliance gap does not automatically mean a breach has occurred. However, unresolved gaps may increase risk and require corrective action.

4. Prioritize Risks Based on Potential Impact

Not every vulnerability presents the same level of risk. Healthcare organizations should consider the likelihood of exploitation, the sensitivity of affected information, and the potential consequences for patient care and business operations.

For example, a weakness affecting a system that supports critical clinical workflows may require more urgent attention than a similar issue on an isolated, low-impact system.

Use a risk register to record each finding, its potential impact, existing safeguards, and recommended actions. The NIST Guide for Conducting Risk Assessments provides a useful methodology for evaluating information security risks.

Key actions include:

• Assess the likelihood and potential impact of each identified risk.
• Consider patient safety, data confidentiality, system availability, and recovery requirements.
• Assign risk levels using a consistent scoring method.
• Identify the systems and business owners responsible for addressing each finding.
• Prioritize remediation based on risk, urgency, and available resources.

5. Develop a Remediation and Monitoring Plan

The final step is to turn assessment findings into an actionable improvement plan. Each identified risk should have a clear next step, a responsible owner, and a target date for resolution or risk treatment.

Some issues may require immediate action, while others may need planned upgrades, additional safeguards, or closer monitoring. Healthcare organizations should also document any accepted residual risks and ensure that acceptance follows their governance and compliance processes.

Key actions include:

• Assign owners and deadlines to remediation tasks.
• Address high-priority vulnerabilities and access control gaps first.
• Define measurable targets for security improvements.
• Monitor remediation progress and verify that corrective actions are effective.
• Schedule follow-up assessments and update the risk register as systems change.

A healthcare IT security assessment is most useful when its findings lead to measurable improvements. Regular reviews help organizations identify new vulnerabilities, adapt to changing threats, and maintain safeguards that support both patient data protection and reliable clinical operations.

Real-World Example #1: OSF Healthcare System Ransomware Incident

A ransomware incident involving OSF Healthcare System demonstrates why healthcare IT security requires both technical safeguards and a structured approach to risk management.

What Happened?

According to the U.S. Department of Health and Human Services (HHS), OSF discovered files infected with the Nephilim ransomware variant in April 2021. The incident resulted in the exfiltration of protected health information (PHI) belonging to 53,907 individuals. The affected information included medical record numbers, diagnosis and treatment details, prescription information, and health insurance information.

In July 2026, HHS announced a settlement resolving its investigation into potential violations of the HIPAA Privacy, Security, and Breach Notification Rules. OSF agreed to pay $552,250 and implement a corrective action plan monitored by HHS for two years.

What Did the Investigation Highlight?

HHS identified potential compliance failures involving risk analysis and breach notification. In particular, the investigation found that OSF had potentially failed to conduct an accurate and thorough assessment of risks and vulnerabilities affecting its electronic protected health information (ePHI).

The case highlights an important distinction: having security tools in place is not enough if an organization cannot adequately identify its sensitive data, evaluate the threats to it, and address the resulting risks.

Key Lessons for Healthcare Organizations

Healthcare organizations can draw several practical lessons from this incident:

• Conduct thorough risk analyses: Maintain an inventory of systems and applications that create, receive, store, or transmit ePHI. Assess relevant threats, vulnerabilities, existing safeguards, and potential impacts.
• Turn findings into action: Use a documented risk management plan to prioritize and track remediation activities, assign responsibility, and review unresolved risks.
• Monitor system activity: Implement appropriate audit logging and regularly review activity to help identify suspicious access and support investigations.
• Prepare for breaches: Establish an incident response process that covers containment, investigation, recovery, and timely notification under applicable requirements.
• Review safeguards regularly: Reassess risks as systems, vendors, workflows, and threats change rather than treating a risk assessment as a one-time exercise.

Practical Takeaway

The OSF case shows why healthcare IT security should connect risk analysis with measurable corrective action. Healthcare organizations should know where ePHI resides, understand how it moves across systems, document identified risks, and verify that appropriate safeguards are implemented and reviewed.

These practices can help organizations strengthen security and prepare for incidents, although no single control can eliminate every cyber risk.

Real-World Example #2: Cybersecurity Risks in Connected Patient Monitors

Medical-device cybersecurity vulnerabilities can create risks beyond data breaches. They may also affect device functionality, patient monitoring, and clinical workflows.

In January 2025, the US Food and Drug Administration (FDA) issued a safety communication about cybersecurity vulnerabilities in certain Contec CMS8000 and Epsimed MN-120 patient monitors. The agency warned that unauthorized actors could potentially access and manipulate affected devices. The communication also described concerns about patient data being transmitted outside the healthcare environment when certain monitors were connected to the internet. The FDA updated the communication in July 2025 after a software patch addressed the vulnerabilities by removing the affected devices’ networking functionality.

The broader risk remains significant. According to RunSafe Security’s 2026 Medical Device Cybersecurity Index, based on a survey of 551 healthcare professionals in the United States, the United Kingdom, and Germany, 24% of surveyed organizations had experienced a cyberattack affecting a medical device. Among organizations reporting such attacks, 80% reported a moderate or significant impact on patient care.

Healthcare organizations can use cases like this to strengthen their medical-device risk assessment process:

• Identify affected and potentially exposed devices: Maintain an inventory of medical devices, including their models, software versions, network connections, and manufacturer support status.
• Assess the exposure: Review manufacturer advisories, applicable FDA safety communications, known vulnerabilities, and the device’s connectivity to other clinical or administrative systems.
• Coordinate remediation: Work with the manufacturer, clinical engineering team, and information security staff to determine whether an approved patch, configuration change, network restriction, or replacement is appropriate.
• Apply compensating controls: Where immediate remediation is not possible, restrict unnecessary network communication, monitor relevant traffic, and document the safeguards used to reduce exposure.
• Validate safety and effectiveness: Confirm that security changes address the identified risk without disrupting the device’s intended clinical function. Document outstanding risks, assign an owner, and establish a review date.

The key lesson is that healthcare risk assessments should evaluate both cybersecurity exposure and potential consequences for patient care. Organizations should prioritize findings according to exploitability, network exposure, existing safeguards, and clinical impact, not simply the number or severity of technical vulnerabilities. Security decisions involving medical devices should also be coordinated with qualified clinical engineering personnel and the manufacturer when necessary.

Future Trends of Healthcare Data Security

Healthcare data security is evolving as organizations adopt AI, connect more medical devices, and expand their use of cloud-based systems. These developments create new opportunities to improve security, but they also introduce risks involving sensitive data, clinical operations, and third-party technologies.

PwC's 2026 healthcare cybersecurity outlook highlights continuing gaps in data protection and preparedness for emerging threats. Healthcare organizations should understand these changes and adapt their security strategies without losing sight of foundational controls.

AI-Driven Threat Detection and Response

AI can help security teams identify suspicious activity and investigate potential threats more efficiently. However, attackers can also use AI to create convincing phishing messages and automate malicious activity. Healthcare institutions must therefore evaluate both the benefits and risks of AI-enabled security tools.

What's Changing?

AI-assisted security tools can analyze login activity, network traffic, and access patterns to flag unusual behavior. They can also help prioritize alerts and accelerate investigations, although their effectiveness depends on data quality, configuration, and human oversight.

What Healthcare Institutions Should Prepare For

• Evaluate AI-assisted monitoring tools for accuracy, reliability, and suitability for healthcare environments.
• Protect sensitive information and credentials accessible to AI systems.
• Require human review for high-impact security decisions and incident responses.
• Monitor AI tools for errors, misuse, and unauthorized access.

Zero-Trust Security Architecture

Remote access, cloud adoption, and third-party integrations have made traditional network boundaries less reliable as a standalone security measure. Zero trust addresses this challenge by requiring access decisions to consider identity, device security, context, and least-privilege permissions.

What's Changing?

Organizations are moving toward access models that continuously evaluate trust rather than automatically trusting users or devices because they are connected to an internal network. This approach can help limit unauthorized access and reduce the impact of compromised accounts. The NIST Zero Trust Architecture guidance provides a framework for understanding and implementing these principles.

What Healthcare Institutions Should Prepare For

• Apply identity verification and least-privilege access policies consistently.
• Review permissions for third-party providers, applications, and automated accounts.
• Evaluate access to critical clinical systems according to operational risk.
• Introduce network segmentation where appropriate to limit the spread of an attack.

Security for Connected Medical Devices

Connected medical devices can introduce vulnerabilities through network connections, outdated software, unsupported components, and limited patching options. Because these devices may support diagnosis, monitoring, or treatment, cybersecurity decisions must account for patient safety and clinical availability.

RunSafe Security's 2026 Medical Device Cybersecurity Index surveyed 551 healthcare professionals across the United States, the United Kingdom, and Germany. It found that 24% of surveyed organizations had experienced a cyberattack affecting a medical device. Among organizations reporting attacks, 80% reported a moderate or significant impact on patient care. These are survey findings, not universal estimates of medical-device attack rates.

What's Changing?

Medical-device cybersecurity is increasingly treated as a lifecycle responsibility, covering procurement, deployment, maintenance, vulnerability management, and retirement. Healthcare institutions must work with manufacturers and clinical engineering teams to address vulnerabilities without creating avoidable clinical risks.

What Healthcare Institutions Should Prepare For

• Maintain an inventory of connected medical devices, software versions, and support status.
• Include cybersecurity requirements in device procurement and vendor evaluations.
• Assess network isolation and other compensating controls for vulnerable devices.
• Coordinate patching, updates, and incident response with manufacturers and clinical engineering teams.
• Plan for unsupported devices that cannot be patched or replaced immediately.

The FDA's February 2026 medical-device cybersecurity guidance provides recommendations for manufacturers on device cybersecurity, labeling, and premarket submissions. Healthcare institutions should also consider manufacturer instructions and applicable clinical safety requirements when managing deployed devices.

Cloud Security and Privacy-Enhancing Technologies

Cloud platforms support electronic health records, telehealth, analytics, and AI applications. However, sensitive information may become harder to govern when it moves across multiple systems, service providers, and storage environments.

What's Changing?

Healthcare institutions are paying greater attention to how sensitive data is collected, stored, accessed, shared, and retained throughout its lifecycle. Privacy-enhancing technologies, such as de-identification and federated learning, may support certain analytical use cases while reducing the need to share identifiable patient information. Their effectiveness depends on the implementation and the specific risks involved.

PwC's 2026 healthcare cybersecurity outlook found that 35% of surveyed healthcare organizations had implemented holistic data-risk controls across the entire data lifecycle, compared with 44% across all sectors. The report draws on 381 global healthcare-sector leaders, so these findings should not be interpreted as representative statistics for US hospitals alone.

What Healthcare Organizations Should Prepare For

• Review cloud permissions, configurations, and data-sharing arrangements regularly.
• Map sensitive information across applications, backups, and third-party services.
• Limit unnecessary collection, access, and retention of patient information.
• Assess privacy-enhancing technologies for their suitability, limitations, and residual privacy risks.
• Confirm that cloud providers and other relevant service providers meet applicable security and contractual requirements.

For organizations subject to HIPAA, HHS cloud computing guidance explains responsibilities when cloud service providers create, receive, maintain, or transmit electronic protected health information.

Healthcare organizations should prepare for these developments by improving visibility into their systems, strengthening data governance, and managing risks across connected environments. Emerging technologies can support stronger security, but they work best alongside established safeguards, clear accountability, and ongoing risk management.

When Should Healthcare Providers Consider External IT Security Support?

Healthcare providers must protect patient information, secure clinical systems, and maintain reliable operations. However, limited staffing, specialized expertise, or monitoring capabilities can make these responsibilities difficult to manage internally.

External healthcare IT security support can help address these gaps, strengthen existing safeguards, and improve incident readiness. It is particularly useful when an organization's security needs exceed its internal capacity.

Limited In-House Security Resources

Smaller healthcare organizations may not have dedicated cybersecurity teams. Internal IT staff often manage infrastructure, technical support, and security responsibilities simultaneously, leaving limited time for specialized security work.

External support may be appropriate when:

• Vulnerability reviews and security updates are frequently delayed.
• Internal teams lack experience with healthcare cybersecurity risks.
• Security responsibilities are unclear or difficult to manage.
• Existing controls need independent review or improvement.

External specialists can supplement internal capabilities without requiring a healthcare organization to build a large in-house security team.

Need for Continuous Monitoring and Incident Response

Healthcare organizations that cannot monitor critical systems consistently may benefit from external security monitoring and incident response support. Depending on the service agreement, providers may monitor security logs, investigate alerts, detect endpoint threats, and assist with incident containment and recovery.

Before engaging a provider, clarify monitoring hours, response times, escalation procedures, and responsibilities during a security incident. Confirm how the provider will coordinate with internal IT, privacy, and clinical teams to protect patient safety and maintain essential services.

The HHS Healthcare and Public Health Cybersecurity Performance Goals offer voluntary guidance for strengthening healthcare cybersecurity and prioritizing key protective measures.

Support for Security Assessments and Compliance

External specialists can help healthcare organizations assess vulnerabilities, evaluate existing safeguards, and identify gaps in risk management and compliance processes.

Depending on the engagement, an assessment may cover:

• Risk analysis: Identify and evaluate risks to systems and electronic protected health information (ePHI).
• Technical security: Review system configurations, vulnerabilities, and network protections.
• Access management: Evaluate authentication, permissions, and privileged accounts.
• HIPAA safeguards: Review applicable security rule requirements and supporting documentation.
• Remediation planning: Prioritize findings, assign responsibilities, and recommend corrective actions.

This support can be valuable when internal teams lack the expertise to assess complex environments or independently validate security controls. However, hiring a security provider does not automatically establish HIPAA compliance for a patient portal. Covered entities and business associates remain responsible for their applicable obligations.

Evaluating Managed Healthcare IT Security Services

Healthcare providers that need ongoing assistance may consider managed security services or healthcare-focused IT security providers. Depending on the agreement, services may include continuous monitoring, vulnerability management, security configuration reviews, and incident response assistance.

Evaluate potential providers against the following criteria:

• Healthcare experience: Familiarity with clinical systems, sensitive health information, and patient-care requirements.
• Service coverage: Systems included, monitoring hours, response availability, and service exclusions.
• Incident response: Defined notification timelines, escalation procedures, and coordination responsibilities.
• Compliance support: Assistance with risk analysis, security documentation, and evidence collection.
• Measurable performance: Clear service-level agreements, reporting requirements, remediation tracking, and periodic reviews.
• Third-party safeguards: Appropriate access restrictions, data-handling practices, and contractual protections, including business associate agreements when required under HIPAA.

Before signing an agreement, determine which responsibilities remain with the healthcare organization and which the provider will perform. Also establish how performance will be reviewed and how access will be revoked when the engagement ends.

The right provider should address specific security gaps, complement internal expertise, and support clinical continuity. Clear contractual responsibilities and ongoing oversight help ensure that external services strengthen the organization's security program rather than create additional unmanaged risks.

Conclusion

Healthcare IT security requires a coordinated approach to protecting patient information, maintaining clinical system availability, and managing cybersecurity risks. Healthcare organizations should combine appropriate access controls, encryption, and vulnerability management, tested backups, workforce training, security monitoring, and third-party risk management within a documented security program.

A comprehensive security risk analysis helps organizations identify weaknesses, evaluate their potential impact, and prioritize corrective actions. Regular monitoring, periodic assessments, and incident-response exercises help verify that safeguards remain effective as systems and threats change.

Frequently Asked Questions

1. How often should healthcare organizations conduct a HIPAA security risk analysis?

Healthcare organizations subject to the HIPAA Security Rule should conduct an accurate and thorough risk analysis and update it as needed to reflect changes in their environment. Although HIPAA does not prescribe one universal annual schedule for every organization, periodic reviews and reassessments after significant changes help identify new risks. Organizations should document their methodology, findings, and risk-management actions.

2. What is the difference between a HIPAA risk analysis and a cybersecurity audit?

A HIPAA security risk analysis identifies and evaluates potential risks to the confidentiality, integrity, and availability of electronic protected health information (ePHI). A cybersecurity audit typically examines whether policies, processes, and controls meet specified requirements or organizational standards. The activities can overlap, but an audit alone does not necessarily satisfy the HIPAA risk analysis requirement.

3. Does HIPAA require healthcare organizations to use multi-factor authentication?

The HIPAA Security Rule requires access controls and other safeguards to protect ePHI, but it does not explicitly prescribe multi-factor authentication as a universal requirement for every system and user. MFA is a widely recommended security measure, particularly for remote access and privileged accounts. Organizations should select safeguards based on applicable requirements, their risk analysis, and the systems and access paths involved.

4. How should hospitals secure medical devices that cannot be patched?

Hospitals should first consult the device manufacturer and clinical engineering team to assess available updates and potential patient-safety implications. If patching is not feasible, appropriate compensating measures may include network segmentation, restricting unnecessary communications, monitoring device activity, and limiting access. The organization should document residual risks, assign responsibility, and establish a remediation or replacement plan.

5. What evidence demonstrates that healthcare cybersecurity controls are effective?

Useful evidence includes access review records, MFA enforcement settings, vulnerability remediation reports, firewall configuration reviews, incident investigation records, and successful backup restoration tests. The appropriate evidence depends on the control being evaluated. Organizations should verify that safeguards work in practice rather than relying solely on written policies or proof that a security tool has been installed.

6. What is the difference between vulnerability scanning and penetration testing in healthcare?

Vulnerability scanning identifies known weaknesses in systems, software, and configurations. Penetration testing attempts to exploit weaknesses within an agreed scope to evaluate how an attacker might gain access or affect connected systems. Both can support healthcare security assessments, but neither replaces a comprehensive HIPAA security risk analysis.

7. How can healthcare organizations assess cybersecurity risks from third-party vendors?

Organizations should determine what systems and data a vendor can access, evaluate its security controls, review relevant incident response and recovery arrangements, and restrict access to what is necessary. When a relationship meets HIPAA's business associate criteria, an appropriate business associate agreement is required. Vendor risk reviews should continue throughout the relationship, particularly when services, access permissions, or data flows change.

8. How should healthcare organizations prioritize cybersecurity vulnerabilities?

Healthcare organizations should evaluate vulnerability severity alongside exploitability, system exposure, the sensitivity of affected data, existing safeguards, and potential effects on patient safety and clinical operations. Findings affecting exposed systems or critical clinical services may require urgent attention. A risk register can help teams assign owners, establish remediation deadlines, document exceptions, and verify that corrective actions reduce risk.

9. What should a healthcare cybersecurity incident response plan include?

A healthcare incident response plan should define how staff report incidents, how security teams investigate and contain threats, and how affected systems are recovered. It should also establish escalation responsibilities, communication procedures, evidence preservation, and coordination with clinical leadership, privacy teams, vendors, and relevant authorities. Plans should address patient-care continuity and applicable breach notification obligations, with exercises used to identify gaps.

10. How can healthcare organizations measure whether their security program is improving?

Organizations can track overdue critical vulnerabilities, MFA coverage, successful recovery tests, incident detection and containment times, overdue risk-treatment actions, and recurring security findings. Each metric should have a defined scope, an accountable owner, and a review schedule. Trends over time are more useful than isolated figures, and targets should reflect the organization's risk profile, clinical needs, and applicable obligations.
