Day 10: Pre-commit Hooks & Security Audit

• ~5 min read

What I Built

  • Pre-commit hooks configuration with Gitleaks, Black, Ruff, mypy, and Bandit
  • GitHub Actions CI/CD workflow for automated testing and security scanning
  • Security integration tests for HMAC validation and credential leakage prevention
  • Final security audit checklist ensuring production readiness

Code Highlight

repos:
  - repo: https://github.com/gitleaks/gitleaks
    rev: v8.18.0
    hooks:
      - id: gitleaks
  - repo: https://github.com/psf/black
    rev: 24.1.0
    hooks:
      - id: black
  - repo: https://github.com/PyCQA/bandit
    rev: 1.7.5
    hooks:
      - id: bandit
        args: [-c, .bandit]

Architecture Decision

Chose pre-commit hooks over CI-only checks to catch issues early in development. Gitleaks prevents secret commits, while Bandit and mypy ensure code quality and security from the start. This "shift-left" approach reduces CI failures and improves developer experience.

Testing Results

All security tests pass, covering critical scenarios:

  • HMAC header validation rejects unauthorized requests
  • Replay attack protection blocks old timestamps
  • Health checks remain accessible without authentication
  • Credential values are properly masked in logs

Next Steps

Week 2 complete! Phase 2 begins with advanced AI trading strategies, market data integration, and performance optimization. The foundation is solid - time to build the intelligence layer.
