SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps developers eliminate common security gaps in Java Spring Boot applications by providing concrete guidance for authentication, authorization, input validation, secrets management, transport and header configuration, rate limiting, and dependency security.

Core Features & Use Cases

  • Provides patterns for stateless JWT or opaque token authentication and secure session cookie configuration.
  • Guides method-level authorization using annotations and custom checks to protect admin and sensitive endpoints.
  • Recommends input validation with Bean Validation, safe password hashing with BCrypt or Argon2, and SQL parameterization to prevent injection.
  • Advises CSRF posture based on client type, secure CORS configuration at the filter level, and strict security headers for browsers.
  • Covers secrets management best practices, rate limiting for expensive endpoints, and CI-driven dependency vulnerability scanning.
  • Use case: Secure a REST API serving a single-page application with JWT auth, method guards for admin APIs, and CI checks that fail on known CVEs.

Quick Start

Add JWT authentication, enable method-level authorization, validate inputs with Bean Validation, configure strict CORS and security headers, externalize secrets, and enable dependency scanning.

Frequently Asked Questions about springboot-security

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

FAQPage Schema
How do I secure a Spring Boot REST API with JWT authentication?▼

Spring Boot REST API JWT authentication uses stateless token validation, method-level authorization annotations, and Bean Validation for DTOs to protect endpoints and prevent unauthorized access.

What is the best way to configure method-level authorization in Spring Security?▼

Method-level authorization in Spring Security uses annotation-based access controls on controller methods, combined with custom checks for sensitive admin endpoints, ensuring only authorized roles access restricted operations.

How do I configure CSRF and CORS policies for a Spring Boot single-page application?▼

CSRF and CORS configuration for a Spring Boot SPA requires adjusting CSRF posture based on the client type and applying secure CORS configuration at the filter level to safely allow cross-origin browser requests.

Does Spring Security support BCrypt and Argon2 for password hashing?▼

Spring Security supports BCrypt and Argon2 for password hashing, providing safe credential storage by leveraging adaptable hashing algorithms to protect against brute force attacks.

How do I add CI dependency scanning for known CVEs in Spring Boot?▼

CI dependency scanning for Spring Boot integrates vulnerability checks into your pipeline that fail builds upon detecting known CVEs, ensuring vulnerable libraries are blocked before deployment.

Why do I need Bean Validation for DTOs in Spring Boot security?▼

Bean Validation for DTOs is needed in Spring Boot security to enforce input validation, preventing injection attacks and malformed data from reaching your service layer by rejecting invalid request payloads.
