What problem does it solve?
Prevents common and critical security vulnerabilities by enforcing secure development practices at system boundaries, protecting authentication, data handling, and external integrations to reduce exploitation risk and accidental data exposure.
Core Features & Use Cases
- Boundary validation: Validate and sanitize all external input at API routes and form handlers to stop injection and malformed data.
- Authentication & session safety: Use proven password hashing, secure cookie flags, and rate limiting to prevent account compromise and brute force attacks.
- Data protection & secrets management: Keep secrets out of source control, avoid logging sensitive fields, and use environment-backed configuration.
- Configuration hardening: Apply security headers, strict CORS, and dependency auditing to reduce attack surface and misconfiguration risks.
- Operational triage: Classify vulnerabilities from audits, prioritize fixes by reachability and severity, and document deferrals with review dates.
- Use Case: Adopt this guidance when adding user input endpoints, implementing authentication, handling file uploads, or integrating third-party services.
Quick Start
Perform a security checklist review of your new API endpoint focusing on input validation, authentication checks, and secrets exposure.
