The electric power grid has evolved significantly over the past decade thanks to
many technological advancements and breakthroughs. As a result, the emerging
“smart grid” is quickly becoming a reality. At the heart of these intelligent
advancements are specialized IT systems – various control and automation
solutions such as substation automation systems. To provide end users with
comprehensive real-time information, enabling higher reliability and greater
control, automation systems have become ever more interconnected. To combat the
increased risks associated with these interconnections, we offer a wide range of
cyber security products and solutions for automation systems and critical
infrastructure.
The new generation of automation systems uses open standards such as IEC
60870-5-104, DNP 3.0 and IEC 61850 and commercial technologies, in particular
Ethernet- and TCP/IP-based communication protocols. They also enable
connectivity to external networks, such as office intranet systems and the Internet.
These changes in technology, including the adoption of open IT standards, have
brought huge benefits from an operational perspective, but they have also
introduced cyber security concerns previously known only to office or enterprise IT
systems.
To counter cyber security risks, open IT standards are equipped with cyber security
mechanisms. These mechanisms, developed in a large number of enterprise
environments, are proven technologies. They enable the design, development and
continual improvement of cyber security solutions specifically for control systems,
including substation automation applications.
ABB fully understands the importance of cyber security and its role in advancing
the security of substation automation systems. A customer investing in new ABB
technologies can rely on system solutions where reliability and security have the
highest priority.
