Power systems management and associated information exchange – Data and communications security – Part 3: Communication network and system security – Profiles including TCP/IP (Edition 1.0)
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.
