Open Source Identity and Access Management For Modern Applications and Services
Apereo CAS - Identity & Single Sign On for all earthlings and beyond.
Quick Overview
Spring Security is a powerful and highly customizable authentication and access-control framework for Java applications. It is the de-facto standard for securing Spring-based applications, providing comprehensive security services for Java EE-based enterprise software applications.
Pros
- Highly flexible and customizable to fit various security requirements
- Seamless integration with Spring Framework and other Spring projects
- Robust support for both authentication and authorization
- Active community and regular updates
Cons
- Steep learning curve for beginners
- Complex configuration for advanced use cases
- Can be overkill for simple applications
- Performance overhead in some scenarios
Code Examples
- Basic HTTP Security Configuration:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.permitAll();
}
}
This example configures basic HTTP security, allowing public access to home pages and requiring authentication for other requests.
- Custom UserDetailsService:
@Service
public class CustomUserDetailsService implements UserDetailsService {
@Autowired
private UserRepository userRepository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userRepository.findByUsername(username)
.orElseThrow(() -> new UsernameNotFoundException("User not found"));
return new org.springframework.security.core.userdetails.User(
user.getUsername(),
user.getPassword(),
user.getRoles().stream()
.map(role -> new SimpleGrantedAuthority(role.getName()))
.collect(Collectors.toList())
);
}
}
This example demonstrates a custom UserDetailsService implementation for loading user-specific data.
- Method-level Security:
@Service
public class UserService {
@PreAuthorize("hasRole('ADMIN')")
public void deleteUser(Long userId) {
// Delete user logic
}
@PostAuthorize("returnObject.username == authentication.name")
public User getCurrentUserDetails() {
// Fetch and return user details
}
}
This example shows how to use method-level security annotations to restrict access based on roles and post-authorize results.
Getting Started
To get started with Spring Security, add the following dependency to your Maven pom.xml
:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
For Gradle, add this to your build.gradle
:
implementation 'org.springframework.boot:spring-boot-starter-security'
After adding the dependency, Spring Security will automatically secure your application with HTTP Basic authentication. You can then customize the security configuration by creating a class that extends WebSecurityConfigurerAdapter
as shown in the first code example.

- Less suitable for large-scale enterprise applications with complex security requirements
Code Comparison
node-jsonwebtoken:
const jwt = require('jsonwebtoken');
const token = jwt.sign({ userId: 123 }, 'secret_key', { expiresIn: '1h' });
Spring Security:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().anyRequest().authenticated().and().oauth2ResourceServer().jwt();
}
}
Summary
node-jsonwebtoken is a focused library for JWT handling in Node.js applications, offering simplicity and ease of use. Spring Security, on the other hand, provides a comprehensive security framework for Java applications, including OAuth2 and JWT support among many other features. While node-jsonwebtoken is ideal for smaller projects or microservices requiring JWT authentication, Spring Security is better suited for large-scale enterprise applications with complex security needs.
Checklist of the most important security countermeasures when designing, testing, and releasing your API
Pros of API-Security-Checklist
- Lightweight and easy to understand for developers of all levels
- Provides a quick reference for API security best practices
- Language-agnostic, applicable to various tech stacks
Cons of API-Security-Checklist
- Not an actual implementation, just a guideline
- Lacks detailed explanations or code examples
- Requires manual implementation of security measures
Code Comparison
API-Security-Checklist doesn't provide code examples, as it's a checklist. Spring Security, on the other hand, offers robust implementation:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/public/**").permitAll()
.anyRequest().authenticated()
.and().formLogin();
}
}
Summary
API-Security-Checklist is a concise, easy-to-follow guide for API security best practices, suitable for quick reference across various technologies. However, it lacks implementation details and code examples. Spring Security, while more complex, provides a comprehensive security framework with ready-to-use implementations for Java applications, offering more robust and integrated security solutions.
The OWASP Cheat Sheet Series was created to provide a concise collection of high value information on specific application security topics.

Code Comparison
Spring Security:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/admin/**").hasRole("ADMIN");
}
}
CheatSheetSeries (example from Authentication Cheat Sheet):
String password = getPassword();
String salt = getSalt();
int iterations = 10000;
int keyLength = 256;
byte[] hash = pbkdf2(password, salt, iterations, keyLength);
Spring Security is a full-fledged security framework for Java applications, providing ready-to-use implementations of security features. CheatSheetSeries, on the other hand, offers guidance and best practices for implementing security across various technologies. While Spring Security provides concrete implementations, CheatSheetSeries requires developers to implement the recommended practices manually. The code examples illustrate this difference, with Spring Security showing configuration code and CheatSheetSeries demonstrating a conceptual implementation of password hashing.
