Last Friday, Larry Kivett and I from Deloitte, and Edna Conway of Cisco, participated in a webinar under UTC's auspices on supply chain security; my topic was CIP-013, the supply chain security standard currently under development. The webinar was very well received with lots of questions, and I think you'll find it interesting.
The recording can be found here. Note that you can also find the recording of the previous Deloitte-Cisco webinar on Virtualization and NERC CIP at the same link.
If you have any comments or questions on the webinar, please email me them at firstname.lastname@example.org.
