Understanding Per-Perimeter Posture Assessment

The evaluation of entity authority across the three sovereignty perimeters – Identity, Domain, and Vocabulary – conducted independently for each perimeter. The assessment produces three separate posture ratings rather than a single composite, reflecting the structural independence of the three perimeters. A composite EAS score can mask a critical perimeter weakness.

Frequently Asked Questions

What is a Per-Perimeter Posture Assessment?

It is the evaluation of entity authority conducted independently across each of the three sovereignty perimeters — Identity, Domain, and Vocabulary — producing three separate posture ratings rather than a single composite score.

Why assess each perimeter independently?

A composite EAS score can mask a critical perimeter weakness — an entity might score well overall while having a complete forfeiture at the vocabulary layer, which would be invisible in a single aggregate score.

How often should this assessment be conducted?

Per-Perimeter Posture Assessment should be conducted at minimum quarterly, aligned with the Structured Data Entropy Rate measurement cycle — more frequently during active Corroboration Campaigns or following detected adversarial activity.
