Q

How do we ensure that only the SolarWinds Platform server can initiate communication to the SolarWinds Platform agent?

a. The agent retains a copy of the public Orion certificate obtained during provisioning. Passive mode uses this to authenticate the server.
b. The Server and Agent perform three-way handshake
c. The Agent uses token-ring to authenticate to the Orion Server

A

a. The agent retains a copy of the public Orion certificate obtained during provisioning. Passive mode uses this to authenticate the server.
