Using CIS hardened operating systems

YugabyteDB supports RHEL CIS hardened operating systems based on the following images:

• CIS Red Hat Enterprise Linux 8 Benchmark-Level 1

• CIS Red Hat Enterprise Linux 9 Benchmark-Level 1

To use these images for YugabyteDB or YugabyteDB Anywhere, you need to make the following modifications.

YugabyteDB clusters

To use a CIS hardened image for cluster nodes:

1. Install the image on the nodes.
2. Change the firewall rules.

YugabyteDB Anywhere

To use a CIS hardened image for installing YugabyteDB Anywhere:

1. Install the image on the node.
2. Change the firewall rules for YugabyteDB Anywhere installation.

YugabyteDB Anywhere universe

To use a CIS hardened image for on-premises universe nodes:

1. Install the image on the nodes.
2. Change the firewall rules.
3. If you want SSH access to database nodes, during provisioning, add the yugabyte user to sshd_config.
4. Create a custom tmp directory during provisioning.
5. After you create the on-premises provider, set the provider runtime configuration flag yb.filepaths.remoteTmpDirectory to the custom tmp directory.
6. When creating universes using the provider, set YB-Master and YB-TServer configuration flag tmp_dir to the custom tmp directory.

To use a CIS hardened image for universes on cloud providers:

1. Download the image.
2. Change the firewall rules.
3. Upload the modified image to your cloud provider.
4. Add the modified image to the Linux version catalog.
