工业控制系统中的零信任之旅

在当今日益由软件驱动的环境中，艾默生正通过与零信任成熟度模型保持一致，为 DeltaV™ 分布式控制系统（DCS）与安全仪表系统（SIS）强化网络安全战略，确保 DeltaV DCS 和 SIS 能够抵御未来的威胁。

零信任成熟度模型

零信任成熟度模型围绕五个不同的支柱构建，每个支柱都支持随着时间的推移而逐步实现优化。这些支柱建立在整合所有五大支柱的跨领域能力基础之上。

加强整个 DeltaV 的网络安全

随着网络安全威胁的发展，艾默生正在进行持续投资，以保持 DeltaV DCS 与 SIS 的韧性，并在不断变化的数字环境中保护您的安全。以下是为实现零信任解决方案而计划的安全增强措施示例。

Emerson’s Boundless Automation vision relies on a software-driven foundation, designed to integrate seamlessly with a software-centric Zero Trust cybersecurity approach.

Emerson will fortify the DeltaV DCS and SIS communications at the protocol level to achieve higher cybersecurity standards, ensuring a secure and reliable system.

Emerson will implement the Principle of Least Privilege (POLP) throughout the DeltaV DCS and SIS system to prevent unauthorized access and further reduce the attack surface.

Emerson will enhance the protection of DeltaV embedded nodes (e.g. controllers) against malicious firmware modification with hardware enforced secure boot.
