About the webinar 

Offshore Norge has released Revision 7 of its guideline for cyber security in OT systems, formerly known as NOG 104 and now renamed Offshore Norge 104 (ON 104). The updated guideline introduces important changes and clarifications that organizations operating in the offshore sector need to understand and address. To help the industry navigate the new requirements and their practical implications, DNV has hosted this webinar. 

In addition, DNV introduced a new recommended practice on cyber security barrier management (DNV-RP-G110), providing practical guidance on how to apply barrier management principles to OT cyber security. 

Watch this on-demand webinar to get a clear, practical introduction to how ON 104 will shape OT cyber security on the Norwegian Continental Shelf – and how barrier management can be used to operationalise and strengthen cyber security in practice.
