SM-201-2020: Security architecture for smart metering (draft)

This document provides a recommended security architecture for smart metering systems. The architecture can act as a blueprint for system integrators and the departments maintaining the system. Measures are chosen for the entire system, as this is usually more effective than choosing measures per component. It can be used as a reference by operators who are seeking to implement or to improve the security of a smart metering system, and can be complemented with the smart meter and data concentrator procurement requirements. The architecture is intended to be used together with an information security management system (ISMS) based on ISO 27001:2013 or similar, with each subsection of the document providing the relevant technical security measures to each objective in the ISO 27001 Annex A.

The architecture covers the complete chain from smart meters to central systems, including data concentrators, if these are used.

Draft version 0.3 for review.

EV-301-2019: Security requirements for procuring EV charging stations

This document specifies security requirements that charge point operators can use when procuring charging stations. The requirements can be used directly in tender documents. They cover the technical security features that the charging station should have, and the measures vendors should take to ensure the correct implementation of these features.

The document is an update of the EV Charging Systems Security Requirements from 2016. ENCS has created this document together with ElaadNL.


EV-201-2019: Security architecture for EV charging infrastructure

This document describes a security architecture for electric vehicle charging infrastructure specifying the technical security measures charge poin operators can implement. The architecture can act as a blueprint for system integrators and the departments maintaining the system. The architecture is intended to be used together with an information security management system (ISMS) based on ISO 27001:2013 or similar.

ENCS is creating this document in collaboration with ElaadNL.


DA-301-2019: Security requirements for procuring DA RTUs

This document gives requirements for procuring secure RTUs for use in distribution automation systems, including:

  • medium to low voltage transformer substations;
  • medium voltage transport substations;
  • automatic circuit recloser controllers applied to overhead distribution lines.

The requirements concern the interfaces to the distribution automation system and the users on these interfaces. The measures are aligned with ISO/IEC 27001:2013. They are designed to fit as much as possible into the processes and procedures already in place in the organizations, and to find the needed balance between the assured security level, feasibility by vendors and the operational impact.

This harmonized set of requirements allows grid operators to get secure automation equipment more cost-effectively, saving their time and effort in developing requirements, as they are already freely available. It has been ensured that the requirements are feasible, as they have been tested in a market survey as well as in previous tenders by other operators. Lastly, these requirements save on implementation costs, as vendors get a common baseline to aim at, and only need to implement the security requirements once and then implement updates in their product roadmap.

The requirements are meant for procuring new RTUs, not for legacy systems, although grid operators may analyze which systems can be upgraded, updated or patched, once more, without disrupting the processes and procedures already in place.


DA-201-2019: Security architecture for distribution automation systems

This document provides a recommended security architecture for DA systems. The architecture can act as a blueprint for system integrators and the departments maintaining the system. Measures are chosen for the entire system, as this is usually more effective than choosing measures per component. It should be used as a reference by grid operators who are seeking to implement the RTU procurement requirements as suggested by ENCS. The architecture is intended to be used together with an information security management system (ISMS) based on ISO/IEC 27001:2013 or similar. Each subsection gives the relevant technical security measures to meet an objective in the ISO/IEC 27001 Annex A.

The distribution automation security architecture covers the central maintenance systems and field devices placed in the medium voltage grids, including in:

  • Medium to low voltage transformer substations
  • Medium voltage transport substations
  • Automatic circuit recloser controllers applied to overhead distribution lines

The architecture includes the interfaces of the DA system and the users on these interfaces. The architecture does not include the internal working on the infrastructure and makes no assumptions on it. The supervisory control and data acquisition (SCADA) system is out of scope. It is considered as an external system accessing the distribution automation system.
