This part of IEC 62351, which is a Technical Report, targets the description of security architecture guidelines for power systems based on essential security controls, i.e. on security-related components and functions and their interaction. Furthermore, the relation and mapping of these security controls to the general system architecture of power systems is provided as a guideline to support system integrators to securely deploy power generation, transmission, and distribution systems applying available standards.
