Design Validation Framework
This framework defines how we evaluate the impact of transparent security deployments.
The objective is to replace assumptions with measurable and reproducible results.
Validation Principles
- No assumption without measurement
- Focus on observable network behavior
- Preserve existing control-plane communication
What We Measure
- Deployment impact (e.g. interruption window, packet loss)
- Control-plane behavior (VRRP, HSRP, STP/BPDU)
- Application continuity during partial outages
Methodology
Each validation follows a simple but strict process:
- Establish baseline behavior without the device
- Insert the device in transparent mode
- Measure behavior under identical conditions
- Compare results and identify deviations
Failure Window Definition
A key metric in our validation is the interruption window during deployment.
This is defined as the measurable period during which connectivity is partially or completely disrupted.
Typical indicators include:
- Ping loss duration
- Session interruption
- Control-plane instability
Relationship to Evidence
This framework defines how validation is performed.
Actual results are documented separately:
