1686-2007 IEEE Standard for Substation Intelligent Electronic Devices (IEDs) Cyber Security Capabilities

The functions and features to be provided in substation intelligent electronic devices (lEDs) to accommodate critical infrastructure protection programs are defined in this standard. Security regarding the access, operation, configuration, firmware revision, and data retrieval from an IED is addressed in this standard. Communications for the purpose of power system protection (teleprotection) is not addressed. Encryption for the secure transmission of data both within and external to the substation, including supervisory control and data acquisition, is not part of this standard as this is addressed in other efforts.
