Control 2.20 — PowerShell Setup: Adversarial Testing and Red Team Framework

Scope. This playbook is the canonical PowerShell automation reference for Control 2.20 — Adversarial Testing and Red Team Framework. It orchestrates pre-deployment and scheduled adversarial probes against Microsoft 365 Copilot, Microsoft Copilot Studio, and Azure OpenAI / Azure AI Foundry-backed agents, and emits SHA-256-hashed evidence packs suitable for SEC 17a-4(f) WORM retention.

Hedging. The cmdlets, REST calls, and patterns below support compliance with OCC Bulletin 2026-13 (formerly OCC Bulletin 2011-12), Federal Reserve SR 26-2 (formerly SR 11-7), FINRA Rule 3110 and Regulatory Notice 24-09 (Generative AI / LLM Guidance), SEC Rule 17a-4(b)(4) and 17a-4(f), GLBA §501(b), the NIST AI RMF Generative AI Profile (NIST AI 600-1), and MITRE ATLAS. They do not by themselves guarantee regulatory compliance.

Read the FSI PowerShell baseline first

Before running any command, read the PowerShell Authoring Baseline for FSI Implementations — module pinning, -WhatIf / SupportsShouldProcess, Dataverse compatibility, and SHA-256 evidence emission. Snippets below show abbreviated patterns; the baseline is authoritative when the two diverge.

Implementation boundary — not a delivered automation package

Documentation re-verified: 2026-11-07; no tenant/runtime tests performed. This repository does not ship the named probe, endpoint-adapter, evidence-helper, or validator scripts. These are incomplete patterns, not a verified multi-surface runner or complete release gate. Implement and test surface-specific adapters before use; do not count missing adapters, empty/skipped suites, REVIEW results, or missing evidence as passing.

The example runner does not load its helper, use GoldenDatasetPath, enforce zone/family thresholds, hash every required artifact, validate destination bytes, or provide complete role/cadence attestations. Its exit check blocks explicit failures/errors but not every requirement in Verification & Testing. The firm must supply and validate that implementation.

§0 Wrong-shell trap (READ FIRST)

Adversarial probes against AI agents touch five distinct surfaces. Choosing the wrong one produces silent false-clean evidence — every probe "succeeds" because it never actually reached the agent.

Surface	Connect cmdlet	Module(s)	What it does in 2.20
Copilot Studio Direct Line	OAuth bearer + REST against https://directline.botframework.com	none — Invoke-RestMethod	Sends probe prompts to a Copilot Studio agent endpoint and captures the response
Microsoft 365 Copilot	Delegated Microsoft Graph Copilot Chat API (preview), or interactive testing	Microsoft.Graph.Authentication	Multi-turn text conversations require a Microsoft 365 Copilot add-on license and all documented delegated permissions; application permissions and action/content-generation skills are unsupported. This runner does not implement that adapter
Azure OpenAI / Microsoft Foundry	Connect-AzAccount for management; documented data-plane SDK/API and its own authentication	Az.Accounts, Az.CognitiveServices, appropriate Foundry SDK	Model completions and Foundry agents/evaluations are different interfaces; do not assume endpoint/API parity
Azure AI Content Safety — Prompt Shields one-shot	Connect-AzAccount + REST text:shieldPrompt	Az.Accounts	Validate that a given prompt would be shielded (independent of any agent)
Microsoft Sentinel — reconcile probe with detection	Connect-AzAccount	Az.SecurityInsights, Az.OperationalInsights	KQL query for CopilotInteraction and Defender alert records produced during the probe window

There is no universal PowerShell cmdlet that runs this multi-surface adversarial program. Microsoft PyRIT (Python Risk Identification Tool) is an open-source framework; Foundry also offers an AI Red Teaming Agent for supported targets. Neither automatically implements every FSI family or firm release gate. Wrappers require tested adapters and must still produce the canonical evidence pack (§5).

Use the documented evaluation SDK/API for the project experience: newer cloud workflows use azure-ai-projects, while classic/local workflows can use azure-ai-evaluation. Pin a compatible approved SDK version and retain target/evaluator restrictions, preview status, and results. See the cloud red-teaming workflow and reviewed sources.

0.1 The four most common false-clean defects

Defect	Symptom	Guard
Probe runner targets a stale or mock endpoint	Every prompt returns a canned "I cannot help with that" — defense-rate looks like 100 %	§1 endpoint reachability check; §2 canary prompt that must elicit a substantive response
Install-Module ... -Force without -RequiredVersion	Floating module versions; reproducibility broken; SOX 404 / OCC 2023-17 evidence rejected	Use the §1 install loop with explicit -RequiredVersion
Evidence pack written without SHA-256 manifest	Cannot prove integrity at audit; SEC 17a-4(f) attestation invalid	§5 mandatory Write-FsiEvidence wrapper + manifest.json

§2 Probe runner — adversarial test execution

This pattern creates timestamped evidence names, not an idempotent replay guarantee. Sending prompts can execute agent tools, write conversation state, and create telemetry or charges even without configuration changes. Restrict identities, tools, destinations, and grounding data before invoking tests. Preserve each run instead of overwriting prior evidence.

<#
.SYNOPSIS
    Executes an adversarial test suite against an AI agent endpoint and emits a SHA-256-hashed evidence pack.

.DESCRIPTION
    Documentary probe-runner pattern for Control 2.20 (not idempotent; each run is preserved). Loads test cases from a tagged attack library,
    sends prompts to the agent under test, scores responses against attack/defense indicators,
    and writes a CSV + JSON + SHA-256 manifest evidence pack.

.PARAMETER AgentEndpoint
    Full URL of the agent endpoint. Direct Line / Azure OpenAI / Foundry are all supported.

.PARAMETER EndpointType
    Endpoint type (DirectLine | AzureOpenAI | Foundry). Determines auth and request shape.

.PARAMETER TestSuitePath
    Local path to attack library (must include LIBRARY-VERSION file with tag/commit).

.PARAMETER GoldenDatasetPath
    Optional: path to golden dataset for regression check.

.PARAMETER EvidencePath
    Output directory for evidence pack. Created if missing.

.PARAMETER ZoneLabel
    Z1 | Z2 | Z3 — recorded in evidence pack and in CommandTags telemetry.

.EXAMPLE
    .\Invoke-AdversarialProbe.ps1 -AgentEndpoint 'https://...' -EndpointType DirectLine `
        -TestSuitePath '.\attack-library' -EvidencePath '.\evidence' -ZoneLabel Z3

2.1 Endpoint helpers — Invoke-AgentPrompt

The previous helper was withdrawn: its Direct Line URL omitted /directline, and it treated the send acknowledgement as the bot reply; its Foundry request assumed an unverified endpoint/API/response shape. No replacement adapter is supplied here.

Implement and explicitly load a firm-owned adapter using the selected service's documented interface:

• Direct Line: Send an activity to /v3/directline/conversations/{conversationId}/activities. POST returns an activity ID, not response text. Receive activities through GET/WebSocket, maintain the watermark, distinguish bot replies from user echoes, and enforce timeouts/correlation.
• Channel security: Configure web and Direct Line security. Tokens are conversation-scoped; use returned expires_in and refresh before expiry. Channel credentials do not authenticate the end user.
• Azure OpenAI / Foundry: use the actual model or agent's documented SDK/API, supported model/version, and authentication. Model-completion tests do not exercise the complete agent/tool workflow.
• Microsoft 365 Copilot: the preview Chat API requires a separate licensed, delegated-only adapter; the example EndpointType set does not implement it.

Adapter acceptance must include an actual benign reply, an expected filtered response, an expired-token/error case, and a timeout. An acknowledged POST, user echo, empty text, or transport error is never a successful defense.

---

§3 Capture content-safety baseline (Microsoft Foundry / Azure RAI policy)

Before measuring defense rate, snapshot the applicable assigned configuration and deployment/agent reference to it. Missing Prompt Shields does not imply a fixed defense rate. The RAI-policy read cmdlet below captures an Azure account policy, not every new Foundry guardrail.

param(
    [Parameter(Mandatory)] [string]$ResourceGroup,
    [Parameter(Mandatory)] [string]$AccountName,
    [Parameter(Mandatory)] [string]$RaiPolicyName,
    [Parameter(Mandatory)] [string]$EvidencePath
)

$policy = Get-AzCognitiveServicesAccountRaiPolicy `
    -ResourceGroupName $ResourceGroup `
    -AccountName $AccountName `
    -Name $RaiPolicyName

$ts = Get-Date -Format 'yyyyMMddTHHmmssZ'
$path = Join-Path $EvidencePath "2.20-rai-policy-$ts.json"
$policy | ConvertTo-Json -Depth 10 | Set-Content -Path $path -Encoding UTF8
Add-FsiManifestEntry -Path $path -EvidencePath $EvidencePath -ScriptVersion '1.0.0'

Do not interpret an empty filter selection as passing. Inspect the raw policy schema and assignment using the Prompt Shields documentation. The former loop assumed an unverified object/property/category shape and did not reject absent filters; it was removed rather than presented as a verified evaluator. Confirm enablement, action, intervention points, assignment, and observed detected/filtered results for both controls. Standalone Content Safety detection requires application-side blocking.

---

§4 Reconcile probe with Control 1.21 detection (Sentinel KQL)

After a probe campaign, reconcile only supported, onboarded telemetry with the actual workload, connector schema, and processing window. The KQL below is an unverified starting point: it assumes CopilotActivity fields and counts Defender alerts without an agent-specific join. It must not be used as proof that the tested agent generated detection.

Use the Copilot audit schema for available operation/workload/message/resource IDs. Record workload-specific correlation and confidence, raw signal IDs, event/ingestion times, queries, results, and explicit unsupported/not-applicable/error reasons. An Azure-only model call does not imply a Microsoft 365 audit record. Unrelated alerts, query errors, and not-yet-ingested records are neither a clean pass nor a proven detection defect.

param(
    [Parameter(Mandatory)] [string]$WorkspaceId,
    [Parameter(Mandatory)] [datetime]$WindowStartUtc,
    [Parameter(Mandatory)] [datetime]$WindowEndUtc,
    [Parameter(Mandatory)] [string]$AgentId,
    [Parameter(Mandatory)] [string]$EvidencePath

§5 Evidence helper — Write-FsiEvidence.ps1

Every script in this control writes through these helpers. They emit JSON, compute SHA-256, and append to manifest.json so an auditor can prove integrity.

function Add-FsiManifestEntry {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory)] [string]$Path,
        [Parameter(Mandatory)] [string]$EvidencePath,
        [Parameter(Mandatory)] [string]$ScriptVersion
    )
    $hash = (Get-FileHash -Path $Path -Algorithm SHA256).Hash
    $manifestPath = Join-Path $EvidencePath 'manifest.json'
    $manifest = @()
    if (Test-Path $manifestPath) {
        $manifest = @(Get-Content $manifestPath -Raw | ConvertFrom-Json)
    }
    $manifest += [PSCustomObject]@{
        file           = (Split-Path $Path -Leaf)
        sha256         = $hash
        bytes          = (Get-Item $Path).Length
        generated_utc  = (Get-Date).ToUniversalTime().ToString('o')
        script_version = $ScriptVersion
        control        = '2.20'
    }
    $manifest | ConvertTo-Json -Depth 5 | Set-Content -Path $manifestPath -Encoding UTF8
}

After a campaign completes, copy the entire evidence directory to a Purview-managed retention-locked location (Control 1.19) without modification. Re-hashing at the destination should produce identical SHA-256 values; any drift is a chain-of-custody finding.

§7 Authoring conventions for this playbook

• Every script #Requires -Version 7.4 and #Requires -PSEdition Core.
• Every script supports -WhatIf where it changes anything (the runner only sends prompts, but is still gated by ShouldProcess).
• Every script writes through Add-FsiManifestEntry — no exceptions.
• Preserve separate runs, their timestamps, and nondeterministic outputs; do not overwrite prior evidence or claim idempotence from an unchanged library version.
