The Security Reality Model
A simple structure for leadership: measure security across the lifecycle and across the layers where bypass occurs.
Two axes
Lifecycle
Build → Deploy → Run → Respond
Where assumptions are created—and where reality breaks them.
Layers
Identity → Network → Workload → Data
Where controls must be enforced to matter.
Reality is enforcement + evidence + ownership
Any program can demonstrate “coverage.” Reality requires controls that are enforced on the critical path, evidenced quickly, and owned by someone accountable for outcomes.
What this model prevents
It prevents investing in more visibility while bypass paths, exceptions, and unclear ownership continue to drive incidents.
