AFAAQ / Capability / 05
Cybersecurity
A property of the architecture, applied across every layer at once.
Argument
Security is the one capability that adds no node. It is not a final layer and not a gate at the end — it is a boundary that crosses everything already there.
Role in the system
Cross-cutting by construction.
Every other capability contributes a node to a layer. Security contributes a boundary instead. Identity, encryption, application security, configuration, audit, delivery and resilience each cross the layers they apply to and stop where they do not.
That is what makes coverage a fact about the architecture rather than a claim about the team: the question is not whether a control exists, but which layers it crosses.
System effect
No new node. A boundary instead.
The composition below is the only one on this site where selecting a capability changes nothing in the layer stack and everything about the shape around it.
