A Definitive Guide to OpenEMR Security & Compliance for Healthcare Organizations
OpenEMR, an open-source electronic health record and practice management system, is used at healthcare facilities around the United States and the world. Strict security measures are still required to protect patient data and comply with US healthcare regulations, even if OpenEMR’s popularity and open-source nature are important considerations when selecting an EHR/EMR system. Any EMR system that processes, maintains, or generates protected health information must meet the Health Insurance Portability and Accountability Act’s requirements for patient record privacy, security, and confidentiality.
In this guide, we have explained the fundamental ideas and practices for safeguarding OpenEMR installations and ensuring compliance with the Federal HIPAA/HITECH Standards for EHR and EMR. This guide was developed for IT and security personnel as well as healthcare administrators who work with electronic health record/electronic medical record systems and must comply with Federal regulations. The use of major OpenEMR modules and integrations will be outlined from a security perspective.
HIPAA Security and Privacy Rules
HIPAA security standards for electronic protected health information include administrative, physical, and technical measures. Safeguards include risk analysis and implementation of appropriate policies.
- In order to implement risk analysis, an organization is required to perform a Security Risk Assessment to identify vulnerabilities and implement reasonable controls.
- Whether encryption is reasonable depends on the organization’s circumstances, but if it is a reasonable measure, then it must be implemented. Encryption for ePHI is highly encouraged.
- Regardless of whether encryption is required by the law, there is a strong recommendation (at least by the guidance issued) to encrypt ePHI data both “at-rest” and when it is “in-transit”.
Further, the regulations require the use of audit controls, unique user id’s, automatic log-off for inactive connections, and integrity controls. There are also requirements for covered entities to have written policies, training for employees, and a disaster recovery plan.
The HIPAA privacy rule has additional limitations on the use & disclosure of PHI. Organizations also need to maintain written documentation, such as their risk assessments, written policies, employee training logs, and breach notifications, to show compliance.
OpenEMR installs that are working toward ONC EHR Certification will also meet the same standards as per HIPAA to provide the same level of protection. For example, OpenEMR’s ONC-certified editions require SHA-512 password hashing and enable audit log encryption, and recommend FIPS-compliant SSL ciphers and AES full-disk encryption on devices. These measures support the HIPAA goals of strong authentication and data protection.
Administrative Safeguards and Governance
Every OpenEMR installation must begin with a formal HIPAA risk analysis. Risk assessments should document threats to electronic protected health information and justify the safeguards put in place to protect ePHI. Security risk assessments are necessary in the US for HIPAA compliance and Meaningful Use, as stated in OpenEMR’s documentation.
Update your ePHI rules and processes, appoint a HIPAA Security Officer, and give people regular security training during the risk assessment process.
Policies and Procedures: Establish explicit written policies governing user access, data usage, device controls, and incident response. For example, appoint a Privacy Officer and require every employee to sign a document attesting to their understanding of HIPAA requirements.
Employee Access Controls: Check employee backgrounds and provide access based on their roles. OpenEMR has the capability for detailed user access controls that restrict staff to only access the data and functions they require. Employees who have been transferred or fired must have their access quickly revoked.
Process for Incident Response and Reporting: Develop an incident management plan outlining how to detect, respond to, and report security breaches; teach staff how to recognize and report potential security breaches. They must be reported to the Department of Health and Human Services and affected patients within 60 days after the event, in accordance with HIPAA/HITECH regulations.
Physical Safeguards in OpenEMR
Device and Server Security: Host OpenEMR on cloud infrastructure or safe locations. Restricting physical access to servers (closed server rooms, keycard or biometric access) is a good idea. Make sure you have the right environmental controls (HVAC, fire suppression, uninterruptible power supplies) if you are on-site. Sign BAAs with providers and select data centers with HIPAA-compliant physical safeguards for cloud or co-located servers. As an extra precaution against physical theft, full-disk encryption is advised for any server or workstation holding ePHI.
Backups: Keep regular backups of the OpenEMR database and files. Backups should be stored elsewhere or in a secure cloud, encrypted. Verify backup restores periodically. Backup and restore activities are recorded via OpenEMR’s audit trail, which helps verify that backups take place and are tracked.
Workstation Security: Set up workstations to need strong login credentials and lock the screen after inactivity. Place monitor screens away from public view. Use privacy filters on displays if needed.
Technical Safeguards in OpenEMR
User Authentication and Access Control
Unique User IDs
Every user must log in with a unique username and password. OpenEMR requires this by default. Do not share accounts. OpenEMR’s fine-grained ACL system allows assigning each user specific privileges (e.g., clinical, billing, admin). Its design is “HIPAA-friendly, fine-grained access control”.
Password Policies
Enforce strong password rules. OpenEMR’s Administration > Globals includes a “Require Strong Passwords” setting that mandates password complexity (length, upper/lower case, numbers, symbols). Also set password expiration and reuse restrictions.
For instance, OpenEMR can lock out users by enforcing a minimum password age and history (no reuse) and a limited number of unsuccessful login attempts.
Multi-Factor Authentication (MFA)
Turn on OpenEMR’s integrated MFA to prevent credential theft.
Both U2F hardware tokens and TOTP (time-based one-time passcodes) are supported by the system.
Once activated, users are required to provide a second factor (such as a hardware key or app code) while logging in. This greatly minimizes the risk of unwanted access even if a password is compromised.
Federated/SSO Integration
In enterprise environments, integrate OpenEMR with corporate authentication.
- OpenEMR supports LDAP/Active Directory login (added in version 6.0.0).
- An admin can turn on “Use LDAP for Authentication” and point OpenEMR to an AD/LDAP server.
- OpenEMR 6.1+ also provides Google OAuth login options (via Google Workspace SSO).
- These connections offer centralized identity management and can enforce company-wide access controls.
- For example, enabling Google Sign-In requires specifying a Google OAuth Client ID in globals.
Session Management
Configure automatic logoff of idle sessions. In Globals, set an “Idle Session Timeout” (in seconds) so that if a user is inactive, the session closes.
This prevents an unattended terminal from allowing unauthorized access. (Note: The Admin Globals reference shows the “Idle Session Timeout Seconds” setting under Security.)
Emergency Access
Maintain a process for emergency access (“break the glass”) that still logs all actions. OpenEMR has an “Emergency Login” feature; ensure the credentials are stored securely, and usage is audited.

Encryption of Data
Encryption in Transit
Always use HTTPS to secure data in motion. Install a valid TLS certificate on the web server so that all OpenEMR traffic is encrypted. Configure the server to restrict plain HTTP (port 80) and only listen on port 443 (HTTPS).
Use only strong ciphers (e.g., enabling FIPS-compliant ciphers as recommended for ONC compliance). Ensure transport encryption is enforced for any API or portal connections as well.
Encryption at Rest
HIPAA calls for encryption at rest as a recommended safeguard. Use disk-level or database encryption.
- For instance, you can activate MySQL/MariaDB data-at-rest encryption or operate the database on an encrypted disk.
- Use OpenEMR’s built-in encryption module to encrypt downloaded documents and file attachments by turning on the “Enable Encryption of Items Stored on Drive” global option.
- Additionally, OpenEMR can encrypt its audit log tables, protecting logs from tampering or disclosure.
Document Encryption
OpenEMR contains tools to encrypt and decode sensitive documents. Files can be encrypted while being stored in Administration → Documents and decrypted when they are retrieved (note: older versions used PHP’s mcrypt, while current OpenEMR has upgraded encryption capability). This ensures that PDF or image files of PHI remain encrypted on disk.
Key Management
Keep encryption keys safe. Make sure that the password or private key is kept in a secure, access-restricted location (not on the web server’s document root) if you utilize OpenEMR’s file encryption.
Control access to key/cert storage carefully if the OS is employing database or disk encryption (e.g., use hardware security modules or cloud key vaults if available).
Audit Logs and Monitoring
Enable Auditing
Turn on all relevant audit logs in OpenEMR. In Globals → Logging, ensure “Enable Audit Logging” is ON.
OpenEMR may track events in areas such as Patient Record, Scheduling, Order Entry, Security Administration, and Backups. Numerous events are automatically tracked, including user login and logout, record views and modifications, signature applications, account lockouts, and PHI exports and prints.
Audit Trail Requirements
The OpenEMR audit trail meets HIPAA logging requirements by tracking key actions.
- For example, it captures user logins/logouts, session timeouts, account lockouts, patient record creation/view/update/deletion, appointments (scheduling), query and order activities, authentication failures, digital signature events, PHI export/import (printing or data export), and administrative modifications.
- The logs contain the user ID, timestamp, patient ID, and status. Ensure that the audit tables are protected.
Centralized Monitoring
Exporting logs to a Security Information and Event Management (SIEM) system is something to think about for larger companies. For delivering audit data to an external server, OpenEMR offers minimal ATNA (Audit Trail & Node Authentication) capability (it contains settings for an ATNA audit host, port, and certificates).
You can utilize syslog/integration tools or script exporting audit tables even in the absence of ATNA. Continuously monitor logs for aberrant behavior (e.g., repeated failed logins, after-hours access, or odd data exports).
Log Retention and Review
Maintain audit records for at least six years (under HIPAA). Implement a regular log review process. Schedule periodic inspections to ensure audit logging is operating and to explore any alerts.
Software and System Hardening
Apply Updates
Keep OpenEMR up to date with the latest releases and security fixes. Apply patches as soon as possible because the open-source community regularly releases updates for vulnerabilities found. Additionally, upgrade the database, PHP, web server (Apache/Nginx), and underlying operating system to supported versions with security patches.
Remove Unused Scripts
Remove or disable any setup or sample scripts that are not required after installation or upgrades.
- For instance, remove or secure the contrib and tests directories, setup.php, acl_setup.php, and sql_upgrade.php.
- If these scripts are left open, they may reveal private information.
- Also, remove phpMyAdmin or ensure it is protected by strong passwords and ideally additional authentication (the wiki even suggests using 2FA for phpMyAdmin logins).
Network Configuration
Use a firewall to restrict access. The OpenEMR server should ideally be placed behind a network firewall or cloud security group that only permits the essential traffic (22 only from known IPs, HTTPS/443, and SSH for management).
Limit database connections so only the OpenEMR application server may reach the database port. [39 L102-L105] suggests limiting the server’s port usage to 443. Use a VPN or bastion hosts for remote access, and try to isolate the OpenEMR server in a private subnet.
Server Hardening
Adhere to security best practices when configuring Apache (or Nginx). Turn off. htaccess overrides, disable directory listing, and grant access just to necessary directories.
- Block online access to sites/*/docs, for instance, so that documents can only be served via the application with the appropriate checks.
- Use secure PHP settings (disable dangerous functions, enable error logging, but do not display errors to users). Follow OpenEMR’s PHP settings recommendations.
Database Security
For the OpenEMR DB and MySQL/MariaDB root accounts, use secure passwords. Only grant the OpenEMR database user the bare minimum of permissions.
Modify the default database login information and delete any test databases. Run the database using a non-root OS user if at all possible. Update the database software frequently to fix security flaws.
Transport-Level Security (TLS/SSL)
Ensure HTTPS is properly configured with TLS 1.2 or higher. Turn off outdated SSL protocols. Make use of a reliable CA’s certifications. Renew certifications before expiration.
The ONC guidelines mention the usage of FIPS-compliant ciphers for optimal security. HSTS (HTTP Strict Transport Security) and other headers can also be enabled to safeguard the browser session.
Secure File Uploads
OpenEMR’s settings include a “Secure Upload Files with White List” option. Turn this on so that only safe file types may be uploaded. This stops harmful programs or executables from being uploaded to the server.

Data Protection and Backups
- Encryption of Stored Data: In addition to application-level encryption, use server-level encryption for any storage containing PHI. This includes database storage, backup media, and file storage. HIPAA-compliant transparent encryption alternatives are available from a number of cloud providers, including AWS, Azure, and GCP.
- Frequent Backups: Automate routine file and database backups. Backups should be kept off-site in a safe, secure location (such as encrypted cloud storage). Test backups to make sure data can be restored and keep them for the necessary retention period. Log and audit backup operations; OpenEMR’s audit logging can record backup events to prove compliance with contingency planning rules.
Business Associate Agreements and Cloud Hosting
Make sure that the provider of a cloud or hosted OpenEMR solution is able to support compliance and has signed a HIPAA BAA. Many cloud services (Amazon AWS, Microsoft Azure, Google Cloud) feature HIPAA-eligible products.
- For example, AWS Marketplace offers HIPAA-eligible OpenEMR solutions.
- Verify that the hosting environment enforces security (physical security, encryption at rest, IAM policies).
- Document the hosting setup in your HIPAA compliance documentation and ensure you have control over the encryption keys or database access.
OpenEMR-Specific Security Features and Modules
Audit Logging (Global Setting)
In OpenEMR’s Administration → Globals under Security, confirm that “Enable Audit Logging” is turned on. This ensures every relevant event is recorded. You can fine-tune which events to log (by category) in Globals. (By default, most security events are logged.)
Enable Encryption of Stored Items
OpenEMR’s global setting “Enable Encryption of Items Stored on Drive” should be ON. This ensures any sensitive document or image is encrypted on disk when uploaded via the documents system.
Enforce Strong Passwords
Use the Global “Require Strong Passwords” setting to enforce length and complexity. This should be ON to comply with password policies.
Multi-Factor Authentication Module
If not already visible in your version, install/enable the MFA module. Once enabled, each user can configure a TOTP app or U2F key in their account settings. Admins can require MFA for all users.
LDAP/Directory Integration
Configure LDAP/AD as a login source if desired.
- In Administration → Globals → Security, turn ON “Use LDAP for Authentication” and enter the LDAP server details.
- Users can then log in with their domain credentials. (Note: ensure network connectivity to the LDAP server and that secure LDAP (LDAPS) is used.)
Google Workspace Sign-In
For organizations using Google Workspace (G Suite), OpenEMR 6.1+ can allow Google OAuth logins. Enable “Google Sign-In” in Globals and configure a Google OAuth client ID. This lets users use their Google account for SSO into OpenEMR, which can simplify authentication and leverage Google’s 2FA/Identity management.
Session and Browser Security
Encourage users to log out of OpenEMR at the end of each session. Consider browser extensions or settings to clear cache/cookies after use. Use Chrome or modern browsers for the best support of security features (some modules, like voice input, only work on Chrome).
Audit by Category
In Globals → Logging, you can selectively disable audit logging for performance if needed. For compliance, it is typical to keep all patient records and security admin logging ON, while less critical logs (like routine SELECT queries) could be disabled if performance is an issue. However, audit logs are generally low overhead and important for forensic evidence, so keep them enabled.
Data Interoperability
If using OpenEMR’s FHIR API or HL7 interfaces, secure them like any API. Disable unused APIs in Globals to reduce attack surface (for example, turn off FHIR API if not used). If enabled, require OAuth2 tokens for API access and use secure protocols.
Monitoring, Testing, and Ongoing Compliance
- Regular Security Reviews: Schedule periodic reviews of the system. Perform vulnerability scans (OS, web server, OpenEMR code). Apply any urgent patches. Use tools like OWASP ZAP or automated scanners on the OpenEMR web interface to detect common issues (SQL injection, XSS, etc.), although the core system is generally robust.
- Penetration Testing: For larger organizations, consider hiring external security auditors to penetration-test the system. This can uncover misconfigurations or logic flaws in the deployment that must be fixed to maintain compliance.
- Policy Updates: Revisit policies and risk assessments annually or whenever significant changes occur (like new modules or server moves). Document all configuration changes (e.g., enabling new security modules, updating encryption settings) as part of the compliance record.
- Training and Awareness: Continually educate staff about phishing, password hygiene, and incident reporting. Good human practices are as important as technical controls.
