SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides best-practice security configurations for Spring Boot apps using Spring Security 6.x, covering JWT, OAuth2, CORS, CSRF, method-level security, and rate limiting, helping teams implement secure APIs quickly.

Core Features & Use Cases

  • SecurityFilterChain configuration for stateless API security with JWT and method security.
  • JWT authentication integration with a custom filter and token service.
  • OAuth2 and CORS configuration for modern cloud-based apps.
  • Password encoding and rate limiting to enforce strong credentials and protect endpoints.
  • Secure headers and validation to harden the application and protect data.

Quick Start

Follow these steps to adopt the skill:

  1. Add a SecurityConfig class implementing a SecurityFilterChain bean and a password encoder (BCrypt with a cost factor of 12+).
  2. Implement a JwtAuthFilter and a JwtService to issue and validate tokens from your authentication flow.
  3. Configure basic HTTP security headers (HSTS, CSP) and enable method security annotations in your services.
  4. Ensure sensitive values (e.g., JWT secret) are loaded from environment variables or a secure vault rather than hard-coded.

Frequently Asked Questions about springboot-security

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure stateless JWT authentication in Spring Boot 3.x?▼

Stateless JWT authentication in Spring Boot 3.x is configured by setting up a SecurityFilterChain for stateless API security and implementing a custom JwtAuthFilter with a JwtService to issue and validate tokens.

How do I enable method-level security in Spring Security 6?▼

Method-level security in Spring Security 6 is enabled by applying method security annotations in your services, which allows you to enforce authorization rules directly on specific service methods.

Does this Spring Security 6 configuration handle OAuth2 and CORS?▼

Yes, this configuration handles OAuth2 and CORS for modern cloud-based apps, integrating OAuth2 login alongside stateless JWT authentication and cross-origin resource sharing policies.

What is the recommended BCrypt cost factor for password encoding in Spring Boot?▼

The recommended BCrypt cost factor for password encoding in Spring Boot is 12 or higher, ensuring strong credential hashing when configuring the password encoder bean.

How do I securely manage JWT secrets in a Spring Boot application?▼

JWT secrets in a Spring Boot application are securely managed by loading the sensitive values from environment variables or a secure vault rather than hard-coding them into the codebase.

What security headers should I configure to harden Spring Boot API servers?▼

Security headers to harden Spring Boot API servers include HSTS and Content Security Policy (CSP), configured within the HTTP security setup to protect data and secure deployments.
