scope:

IEC TS 62351-100-6:2022 (E), which is a technical specification, is part of the IEC 62351 suite of standards, which describes test cases for interoperability conformance testing of data and communication security for Substation Automation Systems [SAS] and telecontrol systems which implement IEC TS 62351-6. The tests described in this part do not evaluate the security of the implementation. Thus, citing conformance to this part does not imply that any particular security level has been achieved by the corresponding product, or by the system in which it is used. The goal of this part of IEC 62351 is to enable interoperability by providing a standard method of testing protocol implementations, but it does not guarantee the full interoperability of devices. It is expected that using this specification during testing will minimize the risk of non-interoperability. Additional testing and assurance measures will be required to verify that a particular implementation of IEC TC 62351-6 has correctly implemented all the security functions and that they can be assured to be present in all delivered products. This topic is covered in other IEC standards, for example IEC 62443. The scope of this document is to specify common available procedures and definitions for conformance and/or interoperability testing of IEC 62351-6, the IEC 61850-8-1, IEC 61850-9-2 and also their recommendations over IEC 62351-3 for profiles including TCP/IP and IEC 62351 4 for profiles including MMS. These are the security extensions for IEC 61850 and derivatives to enable unambiguous and standardized evaluation of IEC TS 62351-6 and its companion standards protocol implementations. The detailed test cases per companion standard, containing among others mandatory and optional mandatory test cases per Secure Communication Application Function, secure ASDU (Application Service Data Unit) and transmission procedures, will become available as technical specifications (TS). Other functionality may need additional test cases, but this is outside the scope of this part of IEC 62351. This document is such a technical specification for the mentioned companion standard. This document deals mainly with data and communication security conformance testing; therefore, other requirements, such as safety or EMC (Electromagnetic compatibility) are not covered. These requirements are covered by other standards (if applicable) and the proof of compliance for these topics is done according to these standards.
