# Cloud Hosted AI Model Security Scan
 
## When to Use
Use this skill when a user asks to assess an authorized AI model, AI application,
RAG service, agent, or inference endpoint deployed in AWS, Azure, Kubernetes, or a
custom HTTPS API. The skill is appropriate for Amazon Bedrock, Amazon SageMaker,
Azure AI Foundry, Azure OpenAI, Azure Machine Learning online endpoints, AKS/EKS,
container-hosted inference APIs, and API-gateway fronted model services.
 
## Safety Rules
1. Only assess targets listed in the signed scope file.
2. Do not attempt credential extraction, destructive exploitation, data exfiltration,
   brute-force testing, denial-of-service, or rate-limit bypass.
3. Use read-only cloud permissions except for explicitly approved inference calls.
4. Use the configured rate limits and stop conditions.
5. Escalate to a human reviewer if a test could expose regulated data, invoke a tool
   with side effects, or materially alter a production workload.
 
## Prerequisites
- Python 3.11 or later.
- Node.js 18 or later for the `skills` installer.
- AWS role access for approved accounts and regions.
- Azure service principal or workload identity for approved subscriptions.
- Written approval for every endpoint, model, RAG index, and agent tool to be tested.
- A configured `scan_scope.yaml` file.
 
## Workflow
1. Validate the scope file.
2. Identify target cloud provider and model hosting pattern.
3. Collect endpoint, model, IAM, network, guardrail, logging, and telemetry metadata.
4. Run only approved adversarial prompt, leakage, tool-abuse, and RAG tests.
5. Analyze artifacts, containers, SBOMs, prompts, retrievers, and tool manifests where access exists.
6. Map findings to OWASP LLM Top 10, MITRE ATLAS, NIST AI RMF, and NIST CSF.
7. Generate JSON, Markdown, and executive-summary outputs.
 
## Commands
```bash
python scripts/validate_scope.py --scope scan_scope.yaml
python scripts/agent.py --scope scan_scope.yaml --out out/findings.json
python scripts/render_report.py --findings out/findings.json --out out/report.md
```
 
## Human Escalation Criteria
Escalate immediately when the scanner observes possible regulated data exposure,
production guardrail bypass, tool invocation with external side effects, missing logging
on a high-risk endpoint, overly permissive cloud IAM, public network exposure of a
sensitive inference endpoint, or evidence of active compromise.
 
## Expected Outputs
- `out/findings.json`: structured evidence and framework mappings.
- `out/evidence/*.jsonl`: raw collection records with timestamps and hashes.

Deployment and execution commands
# 1. Create a Python virtual environment
python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate

# 2. Install dependencies with hash-lock support
pip install --upgrade pip pip-tools
pip-compile --generate-hashes --output-file requirements-lock.txt requirements.txt
pip install --require-hashes -r requirements-lock.txt

# 3. Install the public cybersecurity skills library
npx skills add mukul975/Anthropic-Cybersecurity-Skills

# 4. Validate local skill metadata and compile Python snippets
mkdir -p vendor
git clone --depth 1 https://github.com/mukul975/Anthropic-Cybersecurity-Skills vendor/Anthropic-Cybersecurity-Skills
python vendor/Anthropic-Cybersecurity-Skills/tools/validate-skill.py skills/cloud-hosted-ai-model-security-scan

# 5. Validate scope before any cloud or endpoint action
python skills/cloud-hosted-ai-model-security-scan/scripts/validate_scope.py --scope scan_scope.yaml

# 6. Authenticate to cloud providers using approved identities
# AWS example: Windows AWS CLI v2 / IAM Identity Center profile
aws sso login --profile ai-security-scan
aws sts get-caller-identity --profile ai-security-scan

# The scanner then assumes the service-specific roles from scan_scope.yaml:
# - CloudAIModelSecurityScanBedrockRole for Bedrock inventory/runtime checks
# - CloudAIModelSecurityScanSageMakerRole for SageMaker inventory/runtime checks
az login --tenant <tenant-id>
az account set --subscription <subscription-id>

# 7. Run the scanner under the approved output boundary
python skills/cloud-hosted-ai-model-security-scan/scripts/agent.py --scope scan_scope.yaml --out out/findings.json
python skills/cloud-hosted-ai-model-security-scan/scripts/render_report.py   --findings out/findings.json   --template assets/report-template.md   --out out/report.md

# 8. Smoke-test requirement
# Review findings.json, *.evidence.jsonl, and report.md for redaction before distribution.
