Power systems management and associated information exchange - Data and communications security - Communication network and system security - Profiles including TCP/IP
This part of IEC 62351, which is a technical specification, specifies how to provide confidentiality, tamper detection, and message level authentication for SCADA and telecontrol protocols that make use of TCP/IP as a message transport layer. Although there are many possible solutions to secure TCP/IP, the particular scope of this part is to provide security between communicating entities at either end of a TCP/IP connection within the end communicating entities. The use and specification of intervening external security devices (e.g. “bump-in-the-wire”) are considered outside the scope of this technical specification.
