feat: cross-reference existing Network and Data tests into AI pillar by praneeth-0000 · Pull Request #1234 · microsoft/zerotrustassessment

Cross-reference tests across pillars

Adds support for tests to declare multiple pillars, enabling existing Network and Data tests to surface on the AI pillar page without duplicating test logic.

Problem

The AI pillar assessment previously only showed AI-specific tests. Several existing Network and Data tests are directly relevant to AI security posture (e.g. AI Gateway prompt injection protection, Conditional Access for AI workloads), but had no way to appear on the AI pillar page.

Solution

The [ZtTest()] attribute's Pillar property is changed from [string] to [string[]], allowing a test to declare membership in multiple pillars. Restriction logic in Get-ZtAssessmentResults then controls which pillars are visible based on how the assessment was invoked.

Behavior

Invoke-ZtAssessment -Pillar All (default, no preview)

Cross-referenced tests run and appear on their original pillar pages only. The AI pillar page remains empty.

Invoke-ZtAssessment -Pillar All -Preview

The AI pillar page now shows both cross-referenced tests (from Network and Data) and AI-only tests. Cross-referenced tests also continue to appear on their original pillar pages.

Network and Data cross-referenced tests on the AI page:

AI-only tests on the AI page:

Invoke-ZtAssessment -Pillar AI

Only the AI pillar runs. Both cross-referenced tests and AI-only tests appear exclusively on the AI pillar page.

Tests cross-referenced to AI

Test	Original Pillar	Reason
25415 — AI Gateway prompt injection protection	Network	Directly protects AI workloads via GSA
35001–35041 (32 tests) — Conditional Access, Purview, RMS	Data	Data protection controls are critical for AI data pipelines

Pull request overview

This PR enables “cross-referenced” tests to appear under multiple pillars (notably adding existing Network/Data tests into the AI pillar) by allowing multi-pillar metadata in PowerShell and updating the report UI/data model to handle TestPillar as either a string or an array.

Changes:

Expand report model and UI filtering to support TestPillar as string | string[] | null.
Update PowerShell test metadata (ZtTest.Pillar) and selection/filtering logic to support multi-pillar tests.
Add assessment-result post-processing to restrict multi-pillar TestPillar output based on the requested pillar / preview mode behavior.
