APPARATUS AND METHOD FOR SECURING A DISTRIBUTED CONTROL SYSTEM (DCS) |
| 摘要 |
A method includes receiving, at a first distributed control system (DCS) node over a network, information associated with a security manager. The method also includes establishing multiple communication channels between the first DCS node and the security manager over the network using the information, where the communication channels include a non-secure channel and a secure channel. The method further includes receiving security credentials from the security manager at the first DCS node over the non-secure channel and receiving a security policy and an activation time from the security manager at the first DCS node over the secure channel. In addition, the method includes transitioning the first DCS node to communicate with a second DCS node over the network using the security policy at the activation time. |
