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:

# 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:

./scripts/security/slither-scan.sh

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

3. Mythril

Purpose: Dynamic analysis for Solidity contracts

Usage:

./scripts/security/mythril-scan.sh

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

4. Snyk

Purpose: Dependency scanning for Python and Node.js

Usage:

snyk test --severity-threshold=high

Reports: Available in Snyk dashboard

5. Trivy

Purpose: Container image vulnerability scanning

Usage:

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
