The verifier computes the ground-truth action from the *events alone* and scores both sides — the attacker's free-text narrative is never read by the labeler. + +In `defender_only` mode (used for SFT, eval, smoke tests, and the `/demo` UI) the env auto-generates the incident from `tasks/registry.py` and skips straight to the defender turn. + +## Why the reward cannot be hacked + +1. The verifier is a transparent rule set in `verifier.compute_ground_truth(params)`; the *only* inputs are the structured events. The attacker's `narrative` and even its self-claimed `target_label` are ignored. +2. The plausibility checker (`verifier.check_plausibility(params)`) refuses incoherent stories — for example, a "data exfiltration" claim with a purely-internal destination, or a `lolbin_use` event with no `process` field. The attacker's reward is gated on plausibility passing. +3. Schema-violation incidents floor attacker reward at -0.5, so trying to short-circuit pydantic's validators is strictly worse than playing along. + +The anti-hack invariants are pinned in [`tests/test_verifier.py`](tests/test_verifier.py) and [`tests/test_rubric.py`](tests/test_rubric.py). + +## Action space and reward + +Tool names are deliberately **non-reserved** — there is no `reset`/`step`/`state`/`close` clash with the OpenEnv `MCPEnvironment` reserved-name list. + +```yaml +action_space: + craft_incident: + target_label: dismiss | monitor | quarantine_host | block_ip | escalate + category: malware_execution | c2_beacon | data_exfiltration | ... + events: [ { event_type, fields, timestamp, log_id }, ... ] + narrative: string # ignored by the verifier + submit_triage: + action: + cited_log_id: + rationale: short string +``` + +- **Defender**: +1 correct, −1 missed-malicious, −0.3 over-react on benign, −0.05 unnecessary escalate, +0.1 bonus for citing the right triggering log id, −0.1 floor for format violation. +- **Attacker**: +1 iff defender wrong AND incident plausible, −0.5 if schema validation fails, +0.2 novelty bonus, 0 for gibberish. + +Full breakdown: [openenv.yaml](openenv.yaml) and [rubric.py](rubric.py). + +## Run locally + +```bash +python -m venv .venv && source .venv/bin/activate +pip install -r requirements.txt +python server.py # serves on :7860 +``` + +Smoke test from another shell: + +```bash +curl -s http://localhost:7860/health | jq . +curl -s -X POST 'http://localhost:7860/reset?task=stage1_basic&mode=defender_only' | jq . +curl -s -X POST 'http://localhost:7860/step?task=stage1_basic&mode=defender_only' \ + -H 'content-type: application/json' \ + -d '{"submit_triage": {"action": "monitor", "cited_log_id": "L1-0", "rationale": "smoke"}}' | jq . +open http://localhost:7860/demo # Gradio before-vs-after UI +``` + +Run the test suite (CPU only, no GPU deps): + +```bash +pytest -q # 93 passed +``` + +Or via the bundled Python client: + +```python +from client import OpenSOCClient +c = OpenSOCClient() +obs = c.reset(task="stage1_basic", mode="defender_only", seed=1) +result = c.step({"submit_triage": {"action": "monitor", "cited_log_id": "L1-0", "rationale": "ok"}}, + task="stage1_basic", mode="defender_only", seed=1) +print(result) +``` + +## Run the training pipeline + +Full end-to-end procedure: **[TRAIN.md](TRAIN.md)**.

Tier-1 triage is +mostly judgement: look at one alert plus the small log window around +it, and decide whether to dismiss, monitor, quarantine, block, or +escalate. It's also where SOCs are chronically understaffed — a +pipeline that quietly skips real attacks because the human is asleep is +not a hypothetical risk. + +LLMs *should* be able to help. But training one to do this without +poisoning ourselves on the way is hard: + +1. SOC datasets are private; published ones get stale within months. +2. Subjective rewards from another LLM let the trainee reward-hack the + judge, not the world. +3. Self-play between two LLMs (one playing attacker, one defender) + collapses to a degenerate equilibrium unless the reward is *grounded*. + +OpenSOC is our attempt at all three: a synthetic, self-play SOC triage +environment with a **deterministic, schema-driven verifier** as the only +source of reward signal — true Reinforcement Learning with Verifiable +Rewards (RLVR). + +## What's in the env + +The environment exposes the OpenEnv API (`/reset`, `/step`, `/state`, +`/grade`) plus a Gradio "before vs after" UI at `/demo`: + +- **Schema**: a single `schema.py` defines `IncidentParams`, the only + shape the attacker can produce. Enums for event types and triage + actions, structured fields, no free-text "vibes". +- **Attacker**: must emit a structured `craft_incident` action. Free + text is allowed but ignored by the verifier. +- **Verifier**: `verifier.compute_ground_truth(params)` is a pure + function of the structured fields. Authentication failures from a + single source IP at >5 attempts/window get labeled `block_ip`, + malware_exec on a workstation gets `quarantine_host`, etc. This is + the RLVR substrate. +- **Plausibility check**: a separate `verifier.check_plausibility(params)` + rejects gibberish (e.g. malware exec with no malicious indicators), + and the attacker only earns reward when the incident passes + plausibility. This is what neutralises the classic self-play hack + where the attacker just emits noise to confuse the defender. +- **Defender**: chooses one triage action and cites the log_id that + drove the decision. Reward layers are: +1.0 for matching the verifier, + −1.0 for dismiss-on-malicious, −0.3 for over-react on benign, +0.1 + bonus for the correct citation. Dismiss-on-malicious is the cardinal + failure mode in real SOCs and we grade it accordingly. + +## How we trained + +A Qwen2.5-3B-Instruct with LoRA (rank 16) on a single L4: + +1. **SFT warm-start** on 600 (alert, log_window → action+citation+rationale) + gold examples (~12 minutes). This is just to push P(format-compliant + response) from 0% to ~95% so GRPO has signal. +2. **GRPO curriculum** for 200 steps × 4 stages (~3 hours): + - `stage1_basic`: single-event templates (one obvious benign + one + obvious malicious per category). + - `stage2_multi`: malicious signal spread over a multi-event window. + - `stage3_mixed`: benign noise interleaved with malicious events, + stress-tests false-positive suppression. + - `stage4_adversarial`: attacker-controlled distribution. +3. **Eval** on a frozen 200-incident hold-out set (seed bands disjoint + from training, see `tasks/registry.py`). + +Total compute: ~$3 on HF Jupyter L4. All scripts are turn-key +(`scripts/run_full_pipeline.sh`) and the same notebook produces a +`data/demo_examples.json` of 50 before-vs-after pairs that the deployed +Space serves on the free CPU tier. + +## What's actually new here + +Most "self-play LLM" demos either (a) train a judge LLM and call its +score the reward, or (b) hand-code the reward but abandon self-play. +OpenSOC keeps both: + +- **Self-play** is preserved because the attacker is a real model + emitting real (structured) parameters. +- **The reward is verifiable** because it's computed from the structured + parameters, not the attacker's narrative — so the attacker cannot + reward-hack by writing scary text. + +The trick that makes this work is the *plausibility check*: a separate, +deterministic gate on whether the attacker's params even look like a +real incident. This is what stops the attacker from exploring +adversarial null-spaces.
