What it means
The practice turns broad mission and security needs into implementable functions, interfaces, performance conditions, and verification points.
Why it matters
Poor allocation creates gaps between components, duplicated controls, unsafe dependencies, and responsibilities that no owner or mechanism can actually fulfill.
Practical focus
- Decompose mission functions and security loss scenarios
- Allocate prevention, detection, response, and recovery responsibilities
- Define interfaces and timing constraints
- Validate that the complete allocation satisfies the original need
Common mistakes
- Allocating everything to software by default
- Ignoring human and procedural functions
- Assigning one requirement to multiple components without coordination
- Failing to analyze what happens when an allocated function is unavailable
