# Security Scanning Process

## Overview

This document describes the security scanning process for the DeFi Oracle Meta Mainnet project.

## Scanning Tools

### 1. SolidityScan

**Purpose**: Automated contract vulnerability scanning

**Usage**:
```bash
# Manual scan
solidityscan --api-key $API_KEY --project-path .

# CI/CD integration
# See .github/workflows/ci.yml
```

**Reports**: Available in SolidityScan dashboard and Blockscout UI

### 2. Slither

**Purpose**: Static analysis for Solidity contracts

**Usage**:
```bash
./scripts/security/slither-scan.sh
```

**Reports**: `reports/slither/slither-report.json` and `slither-report.txt`

### 3. Mythril

**Purpose**: Dynamic analysis for Solidity contracts

**Usage**:
```bash
./scripts/security/mythril-scan.sh
```

**Reports**: `reports/mythril/*.json` and `*.txt` files

### 4. Snyk

**Purpose**: Dependency scanning for Python and Node.js

**Usage**:
```bash
snyk test --severity-threshold=high
```

**Reports**: Available in Snyk dashboard

### 5. Trivy

**Purpose**: Container image vulnerability scanning

**Usage**:
```bash
trivy image <image-name>
```

**Reports**: SARIF format for GitHub integration

## Scanning Workflow

### Pre-Commit

1. Run `forge fmt --check` for formatting
2. Run `forge test` for unit tests
3. Run Slither for static analysis (optional)

### CI/CD Pipeline

The CI/CD pipeline automatically runs:

1. **Contract Compilation**: `forge build`
2. **Unit Tests**: `forge test`
3. **Slither**: Static analysis
4. **Mythril**: Dynamic analysis
5. **SolidityScan**: Automated scanning (if API key configured)
6. **Snyk**: Dependency scanning
7. **Trivy**: Container scanning

### Pre-Deployment

1. Run all security scans
2. Review all reports
3. Fix high-severity issues
4. Document security decisions
5. Get approval for deployment

## Report Review Process

### 1. High Severity Issues

**Action**: Fix immediately before deployment

**Process**:
1. Review issue details
2. Assess impact
3. Implement fix
4. Re-scan to verify
5. Document fix

### 2. Medium Severity Issues

**Action**: Fix before next release

**Process**:
1. Review issue details
2. Plan fix
3. Schedule for next sprint
4. Track in issue tracker

### 3. Low Severity Issues

**Action**: Fix as time permits

**Process**:
1. Review issue details
2. Assess priority
3. Add to backlog
4. Fix during maintenance

## Security Score Interpretation

### SolidityScan Scores

- **90-100**: Excellent - Production ready
- **70-89**: Good - Minor improvements recommended
- **50-69**: Fair - Should address issues before production
- **0-49**: Poor - Must fix before production

### Slither/Mythril

- **High**: Critical issues - Fix immediately
- **Medium**: Important issues - Fix before release
- **Low**: Minor issues - Fix as time permits
- **Informational**: Best practices - Consider fixing

## Continuous Monitoring

### Automated Scanning

- **On Commit**: CI/CD runs all scans
- **On PR**: Full scan suite
- **Daily**: Scheduled scans for dependencies
- **Weekly**: Comprehensive security audit

### Alerting

Set up alerts for:
- High-severity vulnerabilities
- New vulnerabilities in dependencies
- Security score drops
- Scan failures

## Remediation Process

### 1. Identify Issue

- Review scan reports
- Understand vulnerability
- Assess impact

### 2. Plan Fix

- Research solution
- Design fix
- Test approach

### 3. Implement Fix

- Write code
- Add tests
- Update documentation

### 4. Verify Fix

- Re-run scans
- Verify issue resolved
- Check no regressions

### 5. Deploy

- Deploy fix
- Monitor for issues
- Document resolution

## Best Practices

1. **Scan Early**: Run scans during development
2. **Fix Quickly**: Address issues as soon as found
3. **Document**: Document security decisions
4. **Review**: Regular security reviews
5. **Update**: Keep scanning tools updated
6. **Train**: Train team on security best practices
