Blackbox exposure (ops/control plane)

Why important?

The more operational black box, the more limited classic auditability becomes—compensating controls and verification become more important.

How measured?

• (higher = less black box / more transparency):
• 0 = Highly opaque (control plane/ops not traceable)
• 1 = Low transparency, few information/artifacts
• 2 = Partial transparency, key areas remain a black box
• 3 = Transparency for core areas, but relevant gaps (ops/control plane) remain
• 4 = High transparency (documentation, access model, artifacts) with few gaps
• 5 = Very high transparency + verifiable artifacts (audit/evidence) also for ops/control plane
• N/A = no reliable evidence

Validation questions (RFP)

• Which parts of the ops/control plane are traceable (logs, access protocols, change management)? Which remain a black box?
