# K9x Satan — Security Analysis Tool for Agentic Networks

Adversarial test harness for K9X Shield.

Satan generates structured attacks against a live K9-AIF pipeline and verifies
that every attack is stopped at the Router or Orchestrator boundary. Any attack
that reaches a Squad or Agent is a finding — not a partial pass.

---

## Containment Contract

```
Attack → Router (ingress gate)       → BLOCKED  ✓
              ↓ if not blocked
         Orchestrator (egress gate)  → BLOCKED  ✓
              ↓ if not blocked
         Squad / Agent               → FINDING  ✗  (Shield failed)
```

---

## Defense in Depth — Two Independent Layers

**K9X Shield** applies deterministic, policy-driven checks — 13 handlers total,
wired into the Router's ingress `VulnerabilityChain` and the Orchestrator's
egress `VulnerabilityChain`. Explainable, zero LLM cost, evaluated identically
every run. Evadable by paraphrase, encoding, or wording changes no regex list
can enumerate in advance.

**IBM Guardian** (`granite4.1-guardian:8b` via Ollama) is an optional semantic
layer wrapping every agent's pre/post hooks — it catches paraphrased injection,
subtle goal hijacking, and disguised privilege escalation that survive the
pattern layer. Neither replaces the other: Shield holds with Guardian disabled
entirely (`NoopGovernance`, the default); Guardian only ever adds coverage on
top.

Guardian unavailability (timeout, HTTP error, unreachable endpoint) is never
silently treated as "SAFE" — it produces an explicit `UNAVAILABLE` verdict, and
`governance.on_guardian_unavailable` in `config/config.yaml` decides the policy:
`fail_closed` (default — blocks/redacts), `fail_open` (documented risk), or
`inconclusive` (flags without blocking).

A third governance option, `ShieldGovernance` (`k9_aif_abb.k9_security.vulnerability`),
wires the *same* check classes Router/Orchestrator already use, but at the
agent pre/post hook level — a second valid architectural point for the same
`VulnerabilityChain` ABB.

Prove what Guardian adds instead of asserting it:

```bash
python -m k9x_satan.runner.satan_runner --target http://localhost:6660 \
    --suite full --compare-governance
```

Fires every attack twice — deterministic-only, then deterministic + Guardian —
and reports which findings Guardian closed. A regression (Guardian making a
previously-contained attack pass) is flagged as a bug, not a result.

Out of scope by design (not runtime-checkable at the payload level): training-data
poisoning, vector/embedding attacks (no RAG in this target), misinformation/hallucination.

## Adding a New Attack

1. Create `attacks/my_attack.py` extending `BaseAttack` (`k9_aif_abb.k9_security.attacks.base_attack`)
2. Fire via the shared `attacks/_fire.py` helper — it POSTs to `/api/attack/fire` and
   correctly reports connection failures as `FLAGGED` (inconclusive), never a fabricated `BLOCKED`
3. Add malicious payload to `corpus/` if document-based
4. Register in `runner/attack_registry.py`
5. Run: `python -m k9x_satan.runner.satan_runner --attack my_attack --target http://localhost:6660`

## Adding a New Check

1. Create `target/my_check.py` extending `BaseVulnerabilityCheck` (`k9_aif_abb.k9_security.vulnerability.base_vulnerability_check`)
2. Wire it into `DocumentRouter._build_ingress_chain()` or `DocumentOrchestrator._build_egress_chain()`
3. Write the matching attack (above) to prove it holds

---

## Relationship to K9X Shield

Satan and Shield are symmetric. Every `BaseAttack` targets a specific
`BaseVulnerabilityCheck`. A PASSED result means a new check is needed in Shield.

| Satan Attack | Shield Check |
|---|---|
| `PromptInjectionAttack` | `PromptInjectionCheck` |
| `SearchPoisoningAttack` | `PromptInjectionCheck` (real tool-response fetch from fake_search) |
| `PayloadFloodAttack` | `InputSizeCheck` |
| `MemoryPoisoningAttack` | `MemoryPoisoningCheck` |
| `RequestFloodAttack` | `RequestFrequencyCheck` |
| `SemanticDriftAttack` | `SemanticDriftCheck` |
| `ExecutionBypassAttack` | `ExecutionGuardCheck` |
| `PIIExfiltrationAttack` | `PIIBoundaryCheck` |
| `ToolArgumentAttack` | `ToolArgumentCheck` |
| `HardcodedCredentialAttack` | `HardcodedCredentialCheck` |
| `ShadowToolAttack` | `ToolAuthorizationCheck` |
| `SystemPromptLeakageAttack` | `SystemPromptLeakageCheck` |
| `OutputSanitizationAttack` | `OutputSanitizationCheck` |
