A Framework Lens and the Unified Attack Graph
You cannot defend what you cannot see whole. The final discipline is to stop drawing two maps — one for IT, one for the plant — and draw one. A recognized security framework gives you the shared coordinate system to do it: a common vocabulary for adversary behavior, a structured way to rate exposure, and a standard for building security into industrial systems by design. Use the framework not as a compliance checkbox but as the projector that renders every foothold, pivot, and control point onto a single attack graph from the internet to the motor. When the graph is whole, prioritization becomes obvious: defend the edges an attacker must traverse, in the order that most shortens their path. One surface, one map, one program.

How does adopting a recognized security framework help unify IT and OT defense rather than merely satisfy compliance?
Show the answer
A shared framework provides a common vocabulary for adversary tactics and a consistent way to rate and prioritize exposure across both IT and OT, letting separate teams build one integrated attack graph and agree on which chokepoints to defend first, instead of maintaining two disconnected maps.
