Sistemas y procedimientos de gestión de sesiones de comunicación seguras con dispositivos remotos

摘要

According to various embodiments, a session manager generates, stores, and periodically updates the login credentials for each of a plurality of connected IEDs. An operator, possibly via an access device, may provide unique login credentials to the session manager. The session manager may determine the authorization level of the operator based on the operator's login credentials, defining with which IEDs the operator may communicate. According to various embodiments, the session manager does not facilitate a communication session between the operator and a target IED. Rather, the session manager maintains a first communication session with the operator and initiates a second communication session with the target IED. Accordingly, the session manager may forward commands transmitted by the operator to the target IED. Based on the authorization level of the operator, a session filter may restrict what may be communicated between an operator and an IED.
