Securing OpenEMR

Securing OpenEMR

Overview

With the advent of the Patient Portals, the community is now addressing the issues of how to best secure OpenEMR instances that are open to the web. Doing this requires a firm understanding of securing several parts, which at least include OpenEMR itself, Apache, MySQL, PHP, firewall, router, https, certficates, etc. A forum that began to discuss this issue can be found here.

There is also a very nicely write up on Security Assessment for EMRs (especially regarding HIPAA compliance) on the the OEMR Organization wiki.

This document is still just a work in progress; hopefully as members of the community begin securing their OpenEMR instances for the web, they will place things they learned here in order to help others.

OpenEMR

• After installation/upgrade consider removing(or ensuring no access to) to the following scripts, which are not needed for general OpenEMR use:

• acl_setup.php
• acl_upgrade.php
• sl_convert.php
• setup.php
• sql_upgrade.php
• gacl/setup.php
• ippf_upgrade.php
• entire contrib directory

• (except for the contrib/icd9, contrib/icd10, contrib/snomed and contrib/rxnorm directories)

• After installing a patch consider removing (or ensuring no access to) the following script, which is not needed for general OpenEMR use:

• sql_patch.php

• Passwords

• Enforce strong/unique passwords, which can be set in Administration->Globals->Security.
• Enforce password expiration, which can be set in Administration->Globals->Security.

Network

• On server, consider only opening port 443 (https).
• Consider a firewall that only allows port 443 (https) traffic to the server.

Apache

• General hardening of Apache, which is described here.
• Only allow https (ie. turn off http)
• Do not allow direct web access to the following directories

• sites/*/documents
• sites/*/era
• sites/*/edi

• If not using portal and want to allow users to access over the internet, then consider using client-sided certificates to only allow users access to site
• If want to give access to the patient portals over the internet, then consider using a client-sided certificate to only allow users access to the main OpenEMR login page
• If using third party patient portal, then consider:

• Only allowing the IP address of the third party portal to access the SOAP APIs (for patient access)
• The third party portal could set up a certificate to identify their server as an option to further secure.
• The third party portal could also set up a ssh tunnel method, so the local OpenEMR instance is not open to the web (and possibly not even require an IP address).

MySQL

• Ensure the root password is set to something.

PHP

• Follow the OpenEMR php settings recommendations

XAMPP

• If you are using XAMPP, note that this software is extremely unsecure after installation and you need to secure it (See the XAMPP security instructions to secure your XAMPP installation.).

Codebase

• Ongoing project to prevent sql-injection and cross-scripting attacks.
• Consider adding a specific sqlconf.php override settings when using the patient portal (especially the onsite portal), which can be used to use a separate mysql user (and possibly database).
