Title: SYSTEM AND METHOD FOR SECURE MANAGEMENT OF NETWORK DEVICES
Abstract:
The method may include obtaining, at a network element on a user network and from a user device, a request to access a programmable logic controller (PLC) located in a drilling management network. The method may further include determining, at the network element, whether the user device is authorized for accessing the PLC based at least in part on user access credentials associated with the user device. The method may further include establishing, in response to determining that the user device is authorized, a virtual connection between the user network and the drilling management network. The method may further include terminating the virtual connection.
