Security Patching

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 weekly 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.

Older Ubuntu Versions

These versions no longer receive security patches and require a migration to a newer configuration. Contact us for details.
