To satisfy compliance and security requirements, Healthcare Blocks periodically updates system libraries and software packages in virtual machines when security patches are available in the associated software repositories. The patching process varies according to the type of operating system:

Ubuntu 20

Patched nightly using security patches tagged as "Required" and "Important." The patches are distributed by Canonical, the publisher of the Ubuntu OS, and sourced from repositories hosted by AWS. The virtual machine is rebooted automatically if required for the patch to take effect.

Windows 2019

Patched monthly using security patches tagged as "Critical" and "Security." The patches are distributed by Microsoft. The virtual machine is rebooted automatically if required for the patch to take effect.

Ubuntu 16

This version will reach support end-of-life (EOL) on April 30, 2021, and will no longer receive security patches from Canonical. Please review the current application and database server options and schedule a migration via support ticket. Optionally, you can schedule an in-place upgrade to Ubuntu 18.04, but this process is not without risks.

Older Ubuntu Versions

These versions no longer receive security patches.
