2. © 2011 EnerNex. All Rights Reserved. www.enernex.com Energy Sector Challenges  Security of the control systems utilized in the energy sector is more IMPORTANT than ever before as control system are evolving rapidly – Increasing use of Ethernet and IP communications Increased attack surface – Connections to external systems Supports changing operational and business needs – New and emerging regulatory requirements 2

3. © 2011 EnerNex. All Rights Reserved. www.enernex.com Energy Sector Challenges  Implementing Security is more COMPLICATED than before – End Users are faced with limited security expertise It shouldn’t take a security expert to configure a device properly! – Vendors need alternatives to proprietary solutions – End Users and Vendors need a straight forward method to communicate user needs, product features, and configuration parameters relating to cyber security functions 3

All Rights Reserved. www.enernex.com Lemnos Project Background  Funded by DOE under the Cybersecurity for Energy Delivery Systems (CEDS) Research and Development Program  Ultimate goal is to make interoperability of devices supporting cyber security functions less difficult to the end users – Often labor intensive and requiring extensive security expertise by the end user – Installed configurations often different for various vendor pairs  Lemnos emphasizes the development and use of a common set of configuration parameters

8. © 2011 EnerNex. All Rights Reserved. www.enernex.com Current Lemnos Project Status  Security functions and protocols identified to date – Messaging (Syslog) – Centralized Authentication (LDAP) – Secure channel (IPsec) – Secure remote access (SSH)  Lab testing and field testing continues  DOE funding ending this year – Potential private sector sponsorship in the future – Looking for utility input to identify priorities 8

9. © 2011 EnerNex. All Rights Reserved. www.enernex.com End User Perspective  Enables End Users to choose BEST IN CLASS solutions for various facilities (versus a “one size fits all”) – For example, an electric utility may have unique needs for: -Communications Hub/Control Center -Generating Plant DCS -Substation LAN -Outdoor and Pole top  Reduction in setup/deployment time and effort – Lower Total Cost of Ownership  Reduction in configuration errors  Communicates equipment requirements 9 Lemnos Benefits

10. © 2011 EnerNex. All Rights Reserved. www.enernex.com Vendor Perspective  Permits shortened development cycle by providing reference design – OPSAID reference design available to public  Uses configurations proven in lab and field to secure control system communications in a way that doesn’t trade off reliability  Enhances the vendor’s ability to meet the customer’s needs – Provides a common understanding between customer and vendor 10 Lemnos Benefits
