System Architecture - ai-security-redteam-lab

This document is the system-level architecture attachment for the repository. It keeps the technical stack, runtime boundary, data/control flow, deployment surface, and operating assumptions in one place.

Architecture Summary

Repository-local proof surface for security operations and controlled automation, backed by Python service or lab runtime, GitHub Actions validation.

Primary domain: security operations and controlled automation.

Stack Surface

Cloud Or Local Deployment Boundary

Operating model: segmented ingest, least-privilege response services, audit trails, and emergency rollback boundaries

Deployment patterns

• Security control plane with audit logging, isolation boundaries, and response review gates

Control boundaries

• identity boundary and least-privilege service access
• environment separation for local, staging, and managed runtime paths
• secret storage outside source and deterministic fallback for missing credentials
• observability hooks for logs, metrics, traces, and audit events
• rollback path for deployment, schema, and model changes

Resilience controls

• bounded retries with explicit failure states
• health/readiness checks before operator-facing flows are trusted
• idempotent data or artifact writes where repeat execution is possible
• cost and quota guardrails for hosted services and model adapters

AI And Automation Boundary

Operating model: policy-scored triage, evidence extraction, response drafting, and deterministic replay checks

Engineering patterns

• Map raw events into typed findings, severity labels, response actions, and audit-ready evidence bundles
• Keep automated remediation behind explicit review and rollback boundaries
• Separate deterministic checks from model-generated output so the system remains testable without external credentials
• Capture prompts, inputs, outputs, and decision metadata as inspectable artifacts instead of hidden side effects
• Gate model-assisted actions with policy, confidence, and fallback states before they reach an operator path

Evaluation and model-risk controls

• deterministic fixtures for CI-safe verification
• golden output or schema checks for generated artifacts
• trace capture for prompts, tool calls, inputs, and outputs
• quality gates that fail closed when evidence is missing

Risks to keep explicit

• unsafe tool execution
• secret exposure
• alert fatigue
• unreviewed automated response
