美国电科院( EPRI )网络安全研究团队的一项新的技术更新为高级计量设施(AMI)厂商与资产所有者之间建立的高级计量设施报警和事件通用装置提供了基础。

相应安全警报的标准化将帮助电力公司提高其业务中的互操作性,更迅速地将AMI系统与入侵检测系统、安全信息和事件管理系统进行整合。该更新还提供这样一个帮助:即,如何识别那些基于拟议事件和报警的特定AMI事件。

本次技术更新只涉及有关电表的告警和事件,不支持系列发电机或输入端设备等组件。

该标准化文件的基本点如下:

- AMI安全对象结构和语义的通用定义,将有助于大大提高AMI系统互操作性的 安全度;

- 通用的AMI报警和事件,可以更有效地整合AMI系统与入侵检测系统;

- 目前,许多推荐的安全事件和报警不包含在ANSI C12.19 AMI标准内,但有可能会 在供应商的数据表中得到应用。(国网电科院国电通公司 刘伊萍 编译)

【原文】EPRI update: standardizing security alarms and events

A new technical update from the Electric Power Research Institute""s (EPRI) cybersecurity research team provides a basis for AMI vendors and asset owners to follow in creating a common set of AMI alarms and events.

Standardization the proposed security alarms will help electric utilities enhance interoperability in their operations and more quickly integrate AMI systems with their intrusion detection systems and security information and event management systems. The update also offers help on how to identify specific AMI incidents based on those proposed events and alarms.

The update addresses only alarms and events that come from the meter and not supporting components like the collection engine or other head-end equipment.

Primary points of the paper are:

· A common definition for the structure and semantics of AMI security objects will significantly help increase secure interoperability of AMI systems

· A common set of AMI alarms and events would allow more efficient integration of AMI systems with intrusion detection systems

· Many of security events and alarms recommended are not now included in the ANSI C12.19 AMI standard, but may be implemented in vendor-specific data tables
