Why Identity Is the Foundation
A short opening note on why every security layer I build starts from identity — and why getting it wrong undermines everything above it.
Most security programs are described as a stack of controls — firewalls, endpoint protection, data loss prevention, detection. Useful, but it hides something: those layers only mean anything once you know who is acting, and what they're allowed to do.
That's identity. It's the quietest layer, and the one that decides everything above it.
The order matters
When I build, I start from the bottom:
- Identity — authenticated, authorized, provisioned from one source of truth.
- Endpoint — known, compliant, healthy before it touches a resource.
- Data — classified, labeled, protected so it travels with the file.
- Detection — signal from all of the above, correlated and acted on.
Get identity right and each layer above inherits its discipline. Get it wrong, and you're defending a building with no idea who holds the keys.
