New thinking and new technologies for security in java framework

New security thinking and new technologies in the Java framework are updated to respond to the evolution of the threat landscape, including: adopting a zero-trust architecture, which distrusts all users and devices by default; enhancing API security, focusing on authorization, rate limiting and data verification ;Limit the attack surface and expose only necessary components and functionality. New technologies include: OAuth 2.0: third-party authorization; JWT: self-contained identity or authorization tokens; Spring Security: providing authentication, authorization, and CSRF protection.

New security thinking and new technologies in Java framework

Introduction

Web security for modern applications Crucial. Java frameworks provide powerful security features to help developers build secure applications. This article explores new thinking and new technologies in Java frameworks to address the evolving threat landscape.

New Directions in Security Thinking

• Zero Trust Architecture: Adopt the zero trust principle and distrust all users and devices by default until Until the identity is verified.
• API Security: Focus on protecting APIs, including authorization, rate limiting, and data validation.
• Attack surface minimization: Limit the attack surface exposed by the application to only the necessary components and functionality.

New technologies and practices

1. OAuth 2.0

OAuth 2.0 is an open standard authorization framework. Allows users to grant third-party applications access to their protected resources without sharing their passwords.

Java Practical Case:

// Spring Security 5 配置 OAuth2.0 授权服务器
@EnableAuthorizationServer
public class AuthorizationServerConfig {

    @Override
    protected void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager).tokenStore(tokenStore);
    }

    // 配置令牌存储
    @Bean
    public TokenStore tokenStore() {
        return new JwtTokenStore(accessTokenConverter());
    }

}

2. JWT

JSON Web Token (JWT) is a compact Self-contained token used to represent user identity or authorization information.

Java Practical Case:

// Spring Security 5 配置 JWT 身份验证过滤器
public class JwtAuthenticationFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
            throws ServletException, IOException {
        String token = request.getHeader(JWT_HEADER_KEY);
        if (token != null) {
            try {
                Authentication authentication = jwtTokenProvider.getAuthentication(token);
                SecurityContextHolder.getContext().setAuthentication(authentication);
            } catch (Exception e) {
                logger.error("Invalid JWT token: {}", e.getMessage());
            }
        }
        filterChain.doFilter(request, response);
    }

}

3. Spring Security

Spring Security is a widely used Web security in the Java framework Framework that provides features such as authentication, authorization, and CSRF protection.

Java Practical Case:

// Spring Boot 2.x 配置 Spring Security
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin/**").hasRole("ADMIN")
                .antMatchers("/**").permitAll()
                .and()
                .formLogin().loginPage("/login").permitAll();
    }

}

Conclusion

The Java framework continues to evolve to provide advanced security features to cope with today's threats. New thinking and new technologies such as Zero Trust Architecture, API Security, Attack Surface Minimization, OAuth 2.0, JWT and Spring Security enable developers to build highly secure web applications.
