Secure Remote Access (SRA)

deviceWISE Secure Remote Access feature enables Machine Builders and Factory owners to remotely manage and orchestrate data from their industrial machines. Through the deviceWISE IoT Platform, SRA creates VPN access to machines for the purposes of remediation, troubleshooting, software updates, data collection and many more machine level interactions.

One of the pillars of Industry 4.0, the capability of remotely managing machines, requires direct access to the PLC, CNC's controllers and their dedicated software.

SRA supports both the deviceWISE Edge Asset and Enterprise Gateways. It enables Secure Remote Access to Connected Machines for remote remediation, updates, application operation, etc.

Secure Remote Access Framework

To start, it is necessary to have an application running on the PC. It needs to be connected to a device, that one that should be linked on a LAN to a gateway running the deviceWISE Gateway. The PC and the gateway connect to the Platform for control messages, and the another routing element to handle global load balancing.

Three elements make up the SRA Framework:

• Application

  • Can be any application running on the PC.

  • Requires layer-2 communications because of legacy protocols.

• PC

  • Windows.

  • Admin rights to install tun/tap driver.

  • The PC must establish outbound only connections, there can be no inbound connections to the PC. Ideally, outbound on HTTPS (Port 443).

  • Must support proxies.

• Gateway

  • Linux, should be able to support multiple devices. Must be able to work with standard Linux kernel, no custom-built kernels.

  • Outbound initiated TCP or UDP only.
