There are various security-related topics throughout VOLTTRON’s documentation. This is a quick roadmap for finding security documentaion.

A core component of VOLTTRON is its message bus. The security of this message bus is crucial to the entire system. The VOLTTRON Interconnect Protocol provides communication over the message bus. VIP was built with security in mind from the ground up. VIP uses encrypted channels and enforces agent authentication by default for all network communication. VIP’s authorization mechanism allows system administrators to limit agent capabilities with fine granularity.

Even with these security mechanisms built into VOLTTRON, it is important for system administrators to harden VOLTTRON’s underlying OS.
