Today’s LiveWire Spotlight examines a recently posted draft data request that will be sent out to all NERC-Registered owners and operators – looking for feedback on its purpose, content, effectiveness and turn-around time.  Once vetted by the industry, the request will be issued to collect information related to the use of Internal Network Security Monitoring (INSM) systems to protect low impact BES Cyber Systems (BCS) and medium impact BCS without external routable connectivity (ERC). 

NERC’s Expedited Internal Network Security Monitoring Data Request Proposal has been posted for industry stakeholder review and feedback.   Responses are due by April 14, 2023 and can be entered online at https://www.surveymonkey.com/r/insmdatarequestcomments.
