Cybersecurity Considerations for Power Substation SCADA Systems Using IEC-61850 Communications

Electrical-Substation
When including security controls into a SCADA system design, it is sometimes difficult to separate design
goals from security requirements. The foremost goal for a SCADA system is to provide protection,
automation, and data acquisition. This paper discusses major
vulnerabilities and cybersecurity considerations that require proper analysis when designing and
implementing a secure IEC-61850 standard-based SCADA system within a power substation.

Securing Legacy SCADA Systems Against Cyber Threats

SCADA-image

There are numerous cyber threats and vulnerabilities announced almost daily with warnings across this country directed at our energy and critical infrastructure sectors from various organizations, such as: FBI, DHS, NSA, DOD, DOE, FERC, NERC, CISA, USCYBERCOM, and many more… These warnings have been directed specifically towards the power utility sector as being very vulnerable towards future cyber threats.

For the electric power industry and other service sectors, Supervisory Control & Data Acquisition (SCADA) has performed a crucial role by allowing better decision making through operating, controlling, monitoring and maintaining critical control systems.
With Smart Grid (SG) and Distributed Generation (DG) gaining more popularity results in more 3rd party stakeholders demanding access to utilities’ SCADA system. Some utility SCADA systems are older legacy systems that are in dire need of replacing in order to have:  a more secure system, access to the latest vendor security patch updates, and to allow for better functionality, etc.

One Utility That Implemented Smart Grid to Improve Electric Reliability and Much More

Chatt-EPB
Electric power has evolved from a simple need to a major necessity. Everyday we rely more and more on electricity to do just about everything. When the lights go out, its not just a major inconvenience, but a catastrophe in some cases. A major focus for power distribution utilities is to deliver reliable power to its customers safely and at the lowest possible cost.
Newer state-of-the-art, digital devices are making it possible to achieve near perfect power reliability while offering more monitoring and control functionality of electric grids. Smarter grids are evolving with improved and faster automation systems, working in harmony with: IEDs, SCADA, FLISR, AMI, AMR, DMS, EMS, OMS, etc.

Chattanooga Electric Power Board (EPB) is one utility that has led the way in this effort.

Good Electrical CAD Drafting and Electrical Design Tips

Elec-CAD-Design
Its always important to utilize best design and CAD drafting practices when involved in creating design drawings for various industries, such as: utilities, industrial, commercial, residential, and others. Performing CAD designs for drawings in separate disciplines can be modified or created with different software package suites, like: AutoCAD, Revit, MicroStation, SolidWorks, Visio, etc. These electronic CAD tools help make the CAD designers’ job easier and still requires self-checking and reviews from the CAD operator for ensuring the highest quality and accuracy.
These drafting and design practice tips explained here can help improve your CAD drawings’ clarity and accuracy, including saving you time and efforts in preventing rework and redraws.
