Dear sirs, or madams,

I’d like to ask about the security of corosync. We’re using a Proxmox HA setup in our testing environment and need to confirm it’s compliance with PCI guidelines.

We have a few questions:

Is the communication encrypted?
What method of encryption is used?
What method of authentication is used?
What is the recommended way of separation for the corosync network? VLAN?

Best regards
