For deeper analysis, follow the workflows below. + +### Testing the scripts + +```bash +python scripts/scan_project.py /path/to/some/project --format text +python scripts/scan_secrets.py /path/to/some/project --format text +``` + +## Audit Workflow + +### 1. Reconnaissance + +Before auditing, understand the project: + +```bash +# Identify languages, frameworks, and entry points +find . -type f -name "*.py" -o -name "*.js" -o -name "*.ts" -o -name "*.go" -o -name "*.java" | head -20 +cat package.json pyproject.toml requirements.txt go.mod pom.xml 2>/dev/null +``` + +Key questions: +- What frameworks are used? (Express, Django, Flask, Spring, etc.) +- Where are the entry points? (routes, controllers, API handlers) +- How is authentication handled? +- What external services are called? +- Is user input accepted? Where? + +### 2. Secrets Detection + +Scan for hardcoded credentials, API keys, and tokens. See references/secrets-patterns.md for the full pattern list. + +```bash +python scripts/scan_secrets.py /path/to/project +``` + +Common patterns to check: +- API keys and tokens in source files +- Database connection strings with embedded passwords +- Private keys or certificates committed to the repo +- `.env` files or config files with plaintext secrets +- Secrets in CI/CD configuration files + +### 3.

Critical and high severity findings should be addressed before deployment. + +### 5. Configuration Review + +Check for insecure defaults in configuration files: + +```yaml +# Common misconfigurations to flag: +DEBUG: true # Debug mode in production +ALLOWED_HOSTS: ["*"] # Unrestricted host access +CORS_ALLOW_ALL_ORIGINS: true # Open CORS policy +SECRET_KEY: "default" # Default or weak secret key +SSL_VERIFY: false # Disabled TLS verification +``` + +Check infrastructure configs: +- Dockerfiles: Running as root, exposing unnecessary ports +- CI/CD: Secrets in plaintext, overly permissive permissions +- Cloud configs: Public S3 buckets, open security groups + +### 6. Authentication and Authorization Review + +Key areas to verify: +- Password hashing uses strong algorithms (bcrypt, argon2, scrypt) +- Sessions have appropriate timeouts and rotation +- JWT tokens are validated properly (algorithm, expiry, signature) +- API endpoints enforce authorization checks +- Role-based access control is consistently applied +- Rate limiting is in place for login and
