This article details the security protocols used by OvrC, and instructs system administrators how to enable the capabilities of OvrC to be used through a corporate firewall.
Foundation
- All OvrC communication is initiated by the device and sent outbound to OvrC. There is no need to alter your firewall to allow for inbound traffic.
- Communication is executed with WebSocket protocol. All communication to and from OvrC is done over HTTPS using TLS 1.2.
- OvrC Pro tunnels have a 30-minute timeout. Subsequent communication requires that the device open a new tunnel, which gets sent to a new random port. This applies to networks using the OvrC Pro device.
