What are host security groups vs regular security groups?

What’s the purpose of Host Security Groups option under clouds as shown on the the image. How are they different from security groups?

Great Question. The morpheus agent has the ability to control iptable rules on hosts like docker hosts or kubernetes hosts outside of the cloud-native security group management. This allows one to optionally use internal firewall management rules.

These days, these are rarely used and are mainly there as backups if a native cloud security group solution isn’t available
