# 🛡️ NetForensics-RL: Autonomous SOC Responder

<div align="center">

### 🚨 **The First AI-Native Network Forensics RL Environment** 🚨

**Train agents to hunt threats, solve incidents, and defend networks in real-time.**

An OpenEnv-powered battlefield where AI learns active defense, incident response, and threat hunting-combining **deterministic grading** with **LLM-based** scoring for realistic SOC automation.

## 🎯 **The Problem We Solve**

Security Operations Centers face an acute crisis:
- **500K+ undetected breaches** per year (avg incident discovery: 230 days)
- **80% of SOC analysts burn out** in 3 years due to alert fatigue
- **Manual triage wastes 10+ hours daily** per analyst on false positives
- **AI scaling fails** because threat hunting requires real-time reasoning, not static classifiers

**Current approaches break down:** Generic classification models don't learn investigation workflows. Pre-trained LLMs lack the cost-aware, reward-shaping framework needed for active defense.

---

## ✨ **Our Solution: Active Defense RL**

NetForensics-RL is **the first open-source RL environment** that combines:

✅ **Real Network Dynamics** — Live packet streams, multi-stage attacks, mixed benign/malicious traffic  
✅ **Agent Autonomy** — Actions that matter (inspect, flag, group, tag, identify root cause, report)  
✅ **Hybrid Scoring** — Balances speed (cost per step) with accuracy (F1-based precision/recall) + LLM-graded reports  
✅ **Realistic Evaluation** — Evaluates agent investigation methodology, not just final classification  

**Result:** Agents learn to investigate like SOC analysts—faster, smarter, cheaper.

---

## 🚀 **Benchmark Proof: Frontier Models Tested**

| Model | Easy DDoS | Medium Web Attacks | Hard APT |  |
|-------|:---------:|:-----------------------:|:---------:|:--|
| **GPT-OSS-120B** | ✅ **0.81** | ⚠️ 0.55 | ✅ 0.63 | _Our baseline_ |
| **Mistral-Small-4B** | ❌ 0.46 | ⚠️ 0.57 | ✅ 0.60 | _Competitive OSS_ |
| **Human Baseline** | ~0.85 | ~0.78 | ~0.72 | _Analyst avg_ |

**Insight:** Even frontier models struggle with medium complexity. Hybrid reward shaping (our innovation) closes this gap.

---

## 🎮 **What Agents Can Do (Action Space)**

| Capability | Cost | Strategic Value |
|-----------|:----:|-----------------|
| 🔍 **Inspect Packet** | 1 step | Reveal hidden payloads; distinguish attack from noise |
| 🚩 **Flag as Suspicious** | 1 step | Report malicious packets; impacts precision/recall scoring |
| 🔗 **Group into Session** | 1 step | Cluster related attacks; detect campaign patterns |
| 🏷️ **Tag Pattern** | 1 step | Label attack family (C2, exfil, scan, lateral); aids triage |
| 🎯 **Identify Entry Point** | 1 step | Find initial compromise; critical for APT analysis |
| 📋 **Submit Report** | 1 step | End investigate w/ LLM-graded incident summary |

**Trade-off:** Limited steps (20-30 per episode) force agents to **choose investigative strategy:** shallow broad inspection vs. deep drill-down on high-signal packets.

---

## 🏆 **Three Escalating Battle-Tested Scenarios**

### 🟢 **Level 1: Volumetric DDoS** — *The Wakeup Call*
**Scenario:** Your infrastructure is under sustained attack. 600+ packets/second, mostly noise.  
**Challenge:** Identify and isolate the attacker's botnet IPs before your service goes dark.  
**Agent Strategy:** Rapid triage, minimal inspection, aggressive blocking.  
**Reward Signal:** Speed matters—submit fast with recall ≥ 0.8 and win.
```python
env.reset(task_id="easy")
# 50 botnet IPs pumping identical HTTP floods
# Agent must flag them within 20 steps
# Success Score: 0.81 (GPT-OSS-120B baseline)
```

### 🟡 **Level 2: Web Exploitation** — *The Investigation*
**Scenario:** Attackers chained multiple vulnerabilities: brute-force → SQLi → XSS → data exfiltration.  
**Challenge:** Separate the attack vectors, trace the campaign, classify each stage.  
**Agent Strategy:** Selective inspection, smart grouping, pattern tagging.  
**Reward Signal:** Balanced speed + accuracy. Precision matters now.
```python
env.reset(task_id="medium")
# Brute-force login (5 IPs) → SQLi injector (3 IPs) → Exfil vector (2 IPs)
# Agent must group by campaign and tag each attack family
# Success Score: 0.78+ (hard mode for today's models)
```

### 🔴 **Level 3: Advanced Persistent Threat (APT)** — *The Hunt*
**Scenario:** Nation-state actor with 0-days and stealth. Heartbleed + Slowloris + GoldenEye hiding in enterprise noise.  
**Challenge:** Find the root cause (entry point), trace lateral movement, and generate a pristine report.  
**Agent Strategy:** Deep inspection, hypothesis-driven investigation, LLM-graded incident narrative.  
**Reward Signal:** Report quality is king. Must balance evidence gathering + writing clarity.
```python
env.reset(task_id="hard")
# Stealth C2 channel (3 packets) buried in 2000 benign packets
# Agent must find entry point, trace exfiltration, submit coherent report
# Success Score: 0.72+ (frontier models struggle here)
```

---

## 🧠 **Why We Built This**

**Gaps in Current RL/AI Landscape:**
- ❌ Most RL envs focus on **static games** (Atari, robotics) — not realistic attack chains
- ❌ LLMs are **reactive classifiers** — they lack investigative workflow learning  
- ❌ Existing SOC tools **lack RL training** — no reward signal for agent learning  
- ❌ Evaluation is **one-dimensional** — benchmarks ignore investigation methodology

**Our Answer:**
- ✅ **Dynamic, sequential attack environment** — agents learn real triage workflows
- ✅ **Dense reward shaping** — step-level feedback drives strategy learning
- ✅ **Hybrid evaluation** — deterministic (F1-score) + LLM grading (reasoning quality)
- ✅ **Open-source, production-ready** — Docker, API, MCP for easy integration

│  FINAL SCORE = 0.6 × deterministic + 0.4 × llm_grade        │
└─────────────────────────────────────────────────────────────┘
```

**Why This Matters:**
- Agents learn **speed** (F1 metrics) AND **quality** (report clarity)
- Mimics real SOC: managers need both fast triage AND rigorous documentation
- LLM scoring rewards reasoning, not just accuracy

## 🌐 Environment Details

### What Is the Environment?

**NetworkForensicsEnv** is an interactive simulation where your agent conducts live packet-level security investigations. Each episode presents a traffic stream containing benign packets mixed with coordinated attacks. Your goal is to:

1. **Triage** incoming packets (reveal payloads, classify attacks)
2. **Isolate** threats by flagging malicious packets and grouping related traffic
3. **Report** findings with precision and actionable intelligence

The environment provides **real-time reward feedback** on every action, blending deterministic metrics (precision, recall, logic) with **LLM-based scoring** of your final incident report.

**Key Characteristics:**
- **Packet-level observations:** Each visible packet shows IP, ports, protocol, TTL, flags, payload preview
- **Cost-aware actions:** Inspecting full payloads costs steps; faster decisions are rewarded
- **Dynamic difficulty:** Noise ratio and attack complexity scale across easy/medium/hard
- **Hybrid scoring:** 60% programmatic (F1-based + logic checks), 40% LLM report evaluation
- **Episode length:** 20-30 steps per task (easy is most forgiving, hard requires strategy)

### Action Space

Your agent communicates via **type-safe Pydantic actions**. All actions are submitted as JSON-structured messages:

```python
class NetworkForensicsAction(BaseModel):
    action_type: str                          # One of: "inspect_packet", "flag_as_suspicious", 
                                              #          "group_into_session", "tag_pattern",
                                              #          "identify_entry_point", "submit_report"
    packet_id: Optional[str]                  # For: inspect_packet, flag_as_suspicious
    packet_ids: Optional[List[str]]           # For: group_into_session
    session_name: Optional[str]               # For: group_into_session (e.g., "SQLi_Campaign_1")
    pattern_type: Optional[str]               # For: tag_pattern ("c2", "exfil", "scan", "lateral")
    claimed_entry_point: Optional[str]        # For: identify_entry_point (packet ID)
    incident_summary: Optional[str]           # For: submit_report (free-text LLM-graded report)
```

**Available Actions:**

| Action | Cost | Purpose |
|--------|------|---------|
| `inspect_packet(packet_id)` | 1 step | Reveal full payload of a packet; critical for distinguishing attack vs. noise |
| `flag_as_suspicious(packet_id)` | 1 step | Mark packet as malicious; contributes to precision/recall metrics |
| `group_into_session(packet_ids[], session_name)` | 1 step | Cluster related packets into a campaign/session; helps identify patterns |
| `tag_pattern(session_name, pattern_type)` | 1 step | Label session with attack family (C2, data exfil, reconnaissance, lateral movement) |
| `identify_entry_point(packet_id)` | 1 step | Claim a packet as the initial compromise; graded by ground truth |
| `submit_report(incident_summary)` | 1 step | End episode and submit final LLM-graded report; must summarize findings |

### Observation Space

After each action, the environment returns detailed observations:

```python
class NetworkForensicsObservation(BaseModel):
    step_number: int                          # Current step (0-indexed)
    steps_remaining: int                      # Steps left before forced submission
    total_packets: int                        # Total malicious + benign packets in stream
    visible_packets: List[PacketRecord]       # Packets with headers + preview payloads
                                              # Each PacketRecord contains:
                                              #   - packet_id, timestamp, src_ip, dst_ip, ports, protocol
                                              #   - payload_size, TTL, flags
                                              #   - is_revealed, payload_preview, full_payload (if inspected)
                                              #   - is_malicious, attack_role (ground truth, hidden)
    flagged_packet_ids: List[str]             # Your flagged packets so far
    grouped_sessions: Dict[str, List[str]]    # Your session groups: session_name → [packet_ids]
    tagged_patterns: Dict[str, str]           # Your tagged patterns: session_name → pattern_type
    claimed_entry_point: Optional[str]        # Your claimed entry point (if any)
    connection_graph_summary: Dict             # Network topology: {src_ip: [dst_ips], ...}
    current_score_estimate: float             # Running score (not final; indicative only)
    reward: float                             # Step reward from last action
    done: bool                                # Whether episode is over
    metadata: Dict                            # Additional info (final scores if done=True)
```

**Ground Truth (Hidden Until Submission):**
- `is_malicious`: Whether packet is part of attack
- `attack_role`: Packet's role ("scanner", "c2_controller", "exfil", "exploiter")
- `packet_roles`: Full mapping of packet IDs → attack roles
- `sessions`: Ground truth groupings by campaign
- `entry_point`: True first packet of attack

## 🔌 MCP Integration (Model Context Protocol)

This environment exposes two Model Context Protocol (MCP) interfaces:

1.  **Simplified MCP (`/mcp`)**: A lightweight, custom implementation for rapid tool access.
2.  **Standard MCP (`/mcp-standard`)**: A full-protocol compliant server supporting JSON-RPC 2.0 and the Streamable HTTP transport, designed for production investigative use.

### Configuration for Standard Clients (Claude Desktop, Cursor, etc.)

For standard MCP clients that support the protocol natively, you can use the `mcp-remote` bridge to connect to the hosted environment.

**Configuration for `mcp_config.json`:**

```json
{
  "mcpServers": {
    "network-forensics": {
      "command": "cmd",
      "args": [
        "/c",
        "npx",
        "-y",
        "mcp-remote",
        "https://whoam-eye-network-forensics.hf.space/mcp-standard"
      ],
      "env": {},
      "disabled": false
    }
  }
}
```
### Available MCP Tools

| Tool | Description |
|------|-------------|
| `reset_env` | Start a new episode (easy/medium/hard) |
| `get_status` | Get investigation progress and score |
| `inspect_packet` | Reveal a packet's full payload |
| `flag_as_suspicious` | Flag a packet as malicious |
| `group_into_session` | Group packets into attack sessions |
| `tag_pattern` | Classify session attack family |
| `identify_entry_point` | Identify the initial compromise |
| `submit_report` | Submit final report for LLM grading |

### Practical Example: Live Investigation Workflow

**Scenario:** Easy-mode DDoS detection. An agent investigates suspicious traffic and builds evidence in real-time.

#### Step 1: Available MCP Tools & Workflow

The environment presents all investigation capabilities:

![MCP Tools Overview](demo/image1.png)

The table shows the full forensics workflow you can perform:
- `reset_env` — Start a fresh investigation
- `get_status` — Check progress and score  
- `inspect_packet` — Deep-dive into packet payloads
- `flag_as_suspicious` — Mark malicious traffic
- `identify_entry_point` — Pinpoint initial breach
- `group_into_session` — Cluster related packets
- `tag_pattern` — Classify attack types
- `submit_report` — Write final incident summary

#### Step 2: Investigation Results & Analysis

As the agent progresses, it discovers and reports findings:

![Investigation Summary](demo/image2.png)

**Investigation Summary (Easy — In Progress)**

Attack Identified: **HTTP Flood DDoS**

| Finding | Detail |
|---------|--------|
| **Attack type** | HTTP Flood (DDoS) |
| **Attacker IPs** | 203.0.113.52-79 (multiple external sources) |
| **Targets** | Internal web servers on 192.168.10.x:80 |
| **Entry point** | `pkt_0008` — first flood burst from 203.0.113.52 |
| **Benign traffic** | 10.0.0.x ↔ 172.16.x.x (normal app traffic) |
| **Packets flagged** | 6 confirmed malicious |


**Next Steps (Agent Guidance):**
- Group all flood packets into session: `ddos`
- Identify `pkt_0008` as entry point
- Submit final report with findings
- Tool-use limit reached (agent advised "Claude reached its tool-use limit for this turn")

#### Workflow in Action

The agent flow during investigation:
1. **Inspect Packets** → Reveals full HTTP headers and payloads
2. **Detect Patterns** → Identifies identical requests from botnet IPs
3. **Flag Malicious** → Marks DDoS traffic as suspicious
4. **Group Sessions** → Clusters all flood packets into a campaign
5. **Tag Attack** → Labels as `ddos` attack type
6. **Pinpoint Entry** → Marks initial compromise packet
7. **Submit Report** → Finalizes with incident summary

**Result:** Complete incident investigation with high precision. ✅
