# Preventing Race Condition Vulnerabilities

## Overview

Eliminate TOCTOU and other race condition vulnerabilities through atomic operations, locking, and safe concurrency patterns.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `thread-sanitizer` | Security tooling |
| `helgrind` | Security tooling |
| `golang-race` | 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/preventing-race-condition-vulnerabilities/{output,logs,artifacts}

# Execute primary analysis with thread-sanitizer
echo "[*] Running Preventing Race Condition Vulnerabilities with thread-sanitizer..."

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

# Generate summary report
cat /tmp/preventing-race-condition-vulnerabilities/output/report.json
```

## Workflow

### Step 1: Preparation and Reconnaissance

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

# Set up working directory
mkdir -p /tmp/preventing-race-condition-vulnerabilities/{output,logs,artifacts}
```

### Step 2: Primary Analysis

```bash
# Execute primary analysis with thread-sanitizer
# Refer to Quick Reference above for detailed commands
echo "[*] Running Preventing Race Condition Vulnerabilities with thread-sanitizer..."

# Log all operations
script -q /tmp/preventing-race-condition-vulnerabilities/logs/session.log
```

### Step 3: Deep Investigation

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

# Cross-reference findings
diff /tmp/preventing-race-condition-vulnerabilities/output/primary.json /tmp/preventing-race-condition-vulnerabilities/output/secondary.json
```

### Step 4: Documentation and Reporting

```bash
# Generate structured findings report
cat <<'EOF' > /tmp/preventing-race-condition-vulnerabilities/output/report.json
{
  "technique": "preventing-race-condition-vulnerabilities",
  "domain": "secure-coding",
  "tools_used": ["thread-sanitizer", "helgrind"],
  "findings": [],
  "recommendations": []
}
EOF
```
