Smart Grid Attack Threats
“Energy control systems are subject to targeted cyber attacks.
Potential adversaries have pursued progressively devious means to exploit flaws
in system components, telecommunication methods, and common operating systems
found in modern energy systems with the intent to infiltrate and sabotage
vulnerable control systems. Sophisticated cyber attack tools require little technical
knowledge to use and can be found on the Internet, as can manufacturers’
technical specifications for popular control system equipment.”

Cyber Security Challenges
• The challenge is complex and continuously
changing
• Legacy systems need to be protected
• Number and geographic location of end points
• Relationship to physical security
• Systems are 7x24 and critical
• The human element / social engineering

The N-Dimension Viewpoint
• Cyber security is an absolute requirement for the Smart
Grid
• Smart Grid deployments will fail without proper cyber
security
• A strong security posture can be established so that the
benefits can be realized from Smart Grid deployments
• Ontario can establish a leadership position:

Recommendations
• View cyber security as a critical element of your Smart Grid
deployment
• Apply the defense in depth concept isolating and segregating
systems and applications, then allow selected connectivity
– Best accomplished at the foundational / design level
• Establish a security management system
– “you can’t manage what you can’t measure”
• Involve your vendors and interconnected partners
• Embed into your corporate governance systems
• Develop and track business case:
– Project by project basis
– Integrated system
• Look to others for learning and suggestions
– such as the Ontario Smart Grid Forum !
