Authorization Boundary
An authorization boundary defines the set of system components, data flows, and external services covered by a single security authorization or ATO decision.

What is an authorization boundary?
It is the drawn edge of the system under assessment: networks, applications, data stores, people, and interconnections. Everything inside must meet the selected control baseline; everything outside is treated as an external system with defined interfaces.
Why It Matters
An oversized boundary inflates cost; an undersized one leaves CUI or production paths unassessed. Boundary diagrams and inventory accuracy are among the first things assessors review.
How Advisedly Helps
Advisedly ties information systems, component inventory, and evidence to explicit system boundaries so SSP and ConMon artifacts stay scoped correctly. See system-centric compliance.
