DNP3 Security: Challenges and Solutions
Alan Scott
Abstract: SCADA networks have historically been designed to optimize efficiency and functionality, without consideration of cyber-security issues. Increasing inter-connectedness of networks and regulatory oversight has now elevated cyber-security to be a mandatory consideration for many network operators.
While DNP3 is among the SCADA protocols most widely adopted by energy utilities internationally, cyber-security was not a consideration of its original design. The DNP Users Group has recently adopted security extensions for the protocol that provide low-overhead mechanisms to ensure reliable authentication of DNP3 messages. These security mechanisms are currently being trialed and evaluated. This paper reports on outcomes and recommendations from these trials.
Practical implications for network operators who wish to apply DNP3 security within their network are discussed, as are future proposed security enhancements for DNP3.

APPLICATION OF ADVANCES IN MAGNETIC ACTUATOR, VACUUM INTERRUPTER AND MICROPROCESSOR TECHNOLOGY TO IMPROVE NETWORK PERFORMANCE THROUGH AUTOMATION AND BETTER PROTECTION GRADING OF AUTO RECLOSERS
Neil O'Sullivan and Tony Stacey
Abstract: Today's electricity utilities are challenged with achieving greater performance and reliability levels than ever before, generally with fewer resources available to them. Use of modern auto reclosers with Intelligent Electronic Device (IED) controllers is one of the most effective tools available to today's utility engineer to increase overhead network performance.
