Updating a Custom SDC Host

The Secure Device Connector (SDC) has been installed on CentOS 7 virtual machines up to now. However, as CentOS has reached its end-of-life and is no longer supported by Firewall in Security Cloud Control, we recommend migrating all SDCs from CentOS 7 to an Ubuntu virtual machine.

For more information, see Migrate an On-Premises Secure Device Connector and Secure Event Connector from a CentOS 7 Virtual Machine to an Ubuntu Virtual Machine.

This procedure applies if you are still using CentOS.

• If you have created your own SDC host you will need to follow the instructions to update based on how you installed Docker. If you used CentOS, yum and Docker-ce (the community edition) the preceding procedure will work.

• If you have installed Docker-ee (the enterprise edtion) or used an alternate method to install Docker, the fixed versions of Docker may be different. You can check the Docker page to determine the correct versions to install: Docker Security Update and Container Security Best Practices.
