# Performing Threat Modeling For Code

## Overview

Apply threat modeling methodologies to code design including STRIDE analysis, attack trees, and data flow diagrams.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `threatdragon` | Security tooling |
| `pytm` | Security tooling |
| `microsoft-tmt` | Security tooling |
| Isolated lab environment for testing | Environment requirement |
| Authorization and signed Rules of Engagement (RoE) | Environment requirement |
| Relevant target samples or systems acquired through authorized channels | Environment requirement |

## Quick Reference

```bash
# Initialize working environment
mkdir -p /tmp/performing-threat-modeling-for-code/{output,logs,artifacts}

# Execute primary analysis with threatdragon
echo "[*] Running Performing Threat Modeling For Code with threatdragon..."

# Validate results with pytm
echo "[*] Cross-validating with pytm..."

# Generate summary report
cat /tmp/performing-threat-modeling-for-code/output/report.json
```

## Workflow

### Step 1: Preparation and Reconnaissance

```bash
# Identify target and gather initial intelligence
file ./target_sample
threatdragon --version 2>/dev/null || echo "Install threatdragon"

# Set up working directory
mkdir -p /tmp/performing-threat-modeling-for-code/{output,logs,artifacts}
```

### Step 2: Primary Analysis

```bash
# Execute primary analysis with threatdragon
# Refer to Quick Reference above for detailed commands
echo "[*] Running Performing Threat Modeling For Code with threatdragon..."

# Log all operations
script -q /tmp/performing-threat-modeling-for-code/logs/session.log
```

### Step 3: Deep Investigation

```bash
# Apply pytm for secondary analysis
echo "[*] Deep investigation with pytm..."

# Cross-reference findings
diff /tmp/performing-threat-modeling-for-code/output/primary.json /tmp/performing-threat-modeling-for-code/output/secondary.json
```

### Step 4: Documentation and Reporting

```bash
# Generate structured findings report
cat <<'EOF' > /tmp/performing-threat-modeling-for-code/output/report.json
{
  "technique": "performing-threat-modeling-for-code",
  "domain": "secure-coding",
  "tools_used": ["threatdragon", "pytm"],
  "findings": [],
  "recommendations": []
}
