This excerpt from the course on security management for critical infrastructure explains how the a security management gateway would support data lifecycle management.
I posted this clip to support the article release for the march issue of the Security Management for Critical infrastructure series on Fierce Smart Grid. Security Management gateways thought not mainstream are needed to bridge the gap in security basis between embedded systems networks and IT networks.
This functionality I describe here links the business functionality, the physical IT & Embedded networks, the trust in the eco-system, and accountability of data. I will continue to describe more details surrounding these as the series unfolds.
