The skill covers a wide range of security principles including authentication, authorization, input validation, data protection, and secure configuration practices.
When to use it
- Implementing authentication or authorization features in your application.
- Reviewing existing codebase for potential security vulnerabilities.
- Setting up security configurations like CORS, CSP, or security headers.
- Handling sensitive data and ensuring its proper encryption and protection.
- Reviewing project dependencies for known vulnerabilities.
Key capabilities
- Expertise in application security for React, Next.js, and NestJS applications.
- Guidance on secure password hashing (bcrypt/argon2), JWT management, and session security.
- Recommendations for implementing RBAC and resource-level authorization.
- Input validation techniques including DTOs with class-validator and parameterized queries.
- Advice on configuring essential security headers like X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
