Role
In DN, a role represents the primary purpose and group-identity of a host. For example, you might
create roles such as Admin Endpoint
, User Endpoint
, WWW Server
, etc. Each machine that you create should be
assigned a role when it is created. Firewall rules are configured for inbound traffic at the role level. Newly created
roles allow only ICMP traffic so that ping
requests can be used for troubleshooting. All other inbound traffic is
denied by default, and the rules can be configured to allow other kinds of traffic from machines belonging to specific
roles.
