What Quarkus Security does

Quarkus Security provides a comprehensive framework for implementing security best practices in Quarkus applications. It covers essential aspects such as authentication, authorization, input validation, and secrets management, ensuring that your applications are robust against various security threats. With support for JWT, OIDC, and role-based access control (RBAC), it allows developers to easily secure their APIs and manage user access effectively.

The skill enables developers to integrate authentication mechanisms like JWT and Basic Auth seamlessly. It also provides tools for implementing authorization using annotations like @RolesAllowed and managing user sessions through SecurityIdentity. Input validation is enforced using Bean Validation, helping to prevent common vulnerabilities such as SQL injection and cross-site scripting (XSS). Additionally, Quarkus Security facilitates the management of sensitive information through environment variables or secret management solutions like Vault.

This skill is particularly useful for developers working on microservices or cloud-native applications where security is paramount. By following the best practices outlined in this skill, teams can ensure that their applications not only comply with security standards but also protect user data and maintain trust. The provided examples demonstrate practical implementations of security features, making it easier for developers to adopt these practices in their projects.

Whether you are building a new application or enhancing an existing one, Quarkus Security equips you with the necessary tools to secure your application effectively. It is designed for developers who prioritize security in their software development lifecycle and wish to implement industry-standard practices with minimal overhead.

When to use it

Use this skill when you need to add authentication and authorization to your Quarkus applications, especially when handling sensitive user data.

When not to use it

This skill may not be suitable for applications that do not require strict security measures or for developers looking for a quick, non-secure solution.

What you can build with it

Adding JWT Authentication

Implement JWT authentication to secure your API endpoints, ensuring only authorized users can access protected resources.

Configuring Role-Based Access Control

Use `@RolesAllowed` to restrict access to certain API endpoints based on user roles, enhancing application security.

Validating User Input

Apply Bean Validation to user input DTOs to prevent invalid data from being processed, reducing the risk of security vulnerabilities.

Quarkus Güvenlik İncelemesi

Kimlik doğrulama, yetkilendirme ve girdi doğrulama ile Quarkus uygulamalarını güvenli hale getirmek için en iyi uygulamalar.

When to Use

  • Kimlik doğrulama ekleme (JWT, OIDC, Basic Auth)
  • @RolesAllowed veya SecurityIdentity ile yetkilendirme uygulama
  • Kullanıcı girişini doğrulama (Bean Validation, özel doğrulayıcılar)
  • CORS veya güvenlik başlıklarını yapılandırma
  • Gizli bilgileri yönetme (Vault, ortam değişkenleri, config kaynakları)
  • Rate limiting veya brute-force koruması ekleme
  • Bağımlılıkları CVE için tarama
  • MicroProfile JWT veya SmallRye JWT ile çalışma

How It Works

Quarkus güvenliğini katmanlı uygulayın: JWT/OIDC veya Basic Auth ile kimliği doğrulayın, SecurityIdentity ve @RolesAllowed ile yetki kararlarını merkezileştirin, Bean Validation ile girdileri sınırlandırın, CORS ve güvenlik başlıklarını açıkça yapılandırın, gizli bilgileri Vault veya ortam değişkenleri üzerinden yönetin.

Examples

Kimlik Doğrulama

JWT Kimlik Doğrulama

// JWT ile korunan resource
@Path("/api/protected")
@Authenticated
public class ProtectedResource {

  @Inject
  JsonWebToken jwt;

  @Inject
  SecurityIdentity securityIdentity;

  @GET
  public Response getData() {
    String username = jwt.getName();
    Set<String> roles = jwt.getGroups();
    return Response.ok(Map.of(
        "username", username,
        "roles", roles,
        "principal", securityIdentity.getPrincipal().getName()
    )).build();
  }
}

Yapılandırma (application.properties):

mp.jwt.verify.publickey.location=publicKey.pem
mp.jwt.verify.issuer=https://auth.example.com

# OIDC
quarkus.oidc.auth-server-url=https://auth.example.com/realms/myrealm
quarkus.oidc.client-id=backend-service
quarkus.oidc.credentials.secret=${OIDC_SECRET}

Özel Kimlik Doğrulama Filtresi

@Provider
@Priority(Priorities.AUTHENTICATION)
public class CustomAuthFilter implements ContainerRequestFilter {

  @Inject
  SecurityIdentity identity;

  @Override
  public void filter(ContainerRequestContext requestContext) {
    String authHeader = requestContext.getHeaderString(HttpHeaders.AUTHORIZATION);

    // Başlık yoksa veya hatalıysa hemen reddet
    if (authHeader == null || !authHeader.startsWith("Bearer ")) {
      requestContext.abortWith(Response.status(Response.Status.UNAUTHORIZED).build());
      return;
    }

    String token = authHeader.substring(7);
    if (!validateToken(token)) {
      requestContext.abortWith(Response.status(Response.Status.UNAUTHORIZED).build());
    }
  }

  private boolean validateToken(String token) {
    // Token doğrulama mantığı
    return true;
  }
}

Yetkilendirme

Rol Tabanlı Erişim Kontrolü

@Path("/api/admin")
@RolesAllowed("ADMIN")
public class AdminResource {

  @GET
  @Path("/users")
  public List<UserDto> listUsers() {
    return userService.findAll();
  }

  @DELETE
  @Path("/users/{id}")
  @RolesAllowed({"ADMIN", "SUPER_ADMIN"})
  public Response deleteUser(@PathParam("id") Long id) {
    userService.delete(id);
    return Response.noContent().build();
  }
}

@Path("/api/users")
public class UserResource {

  @Inject
  SecurityIdentity securityIdentity;

  @GET
  @Path("/{id}")
  @RolesAllowed("USER")
  public Response getUser(@PathParam("id") Long id) {
    // Sahipliği kontrol et
    if (!securityIdentity.hasRole("ADMIN") &&
        !isOwner(id, securityIdentity.getPrincipal().getName())) {
      return Response.status(Response.Status.FORBIDDEN).build();
    }
    return Response.ok(userService.findById(id)).build();
  }

  private boolean isOwner(Long userId, String username) {
    return userService.isOwner(userId, username);
  }
}

Programatik Güvenlik

@ApplicationScoped
public class SecurityService {

  @Inject
  SecurityIdentity securityIdentity;

  public boolean canAccessResource(Long resourceId) {
    if (securityIdentity.isAnonymous()) {
      return false;
    }

    if (securityIdentity.hasRole("ADMIN")) {
      return true;
    }

    String userId = securityIdentity.getPrincipal().getName();
    return resourceRepository.isOwner(resourceId, userId);
  }
}

Girdi Doğrulama

Bean Validation

// KÖTÜ: Validation yok
@POST
public Response createUser(UserDto dto) {
  return Response.ok(userService.create(dto)).build();
}

// İYİ: Doğrulanmış DTO
public record CreateUserDto(
    @NotBlank @Size(max = 100) String name,
    @NotBlank @Email String email,
    @NotNull @Min(18) @Max(150) Integer age,
    @Pattern(regexp = "^\\+?[1-9]\\d{1,14}$") String phone
) {}

@POST
@Path("/users")
public Response createUser(@Valid CreateUserDto dto) {
  User user = userService.create(dto);
  return Response.status(Response.Status.CREATED).entity(user).build();
}

Özel Doğrulayıcılar

@Target({ElementType.FIELD, ElementType.PARAMETER})
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = UsernameValidator.class)
public @interface ValidUsername {
  String message() default "Invalid username format";
  Class<?>[] groups() default {};
  Class<? extends Payload>[] payload() default {};
}

public class UsernameValidator implements ConstraintValidator<ValidUsername, String> {
  @Override
  public boolean isValid(String value, ConstraintValidatorContext context) {
    if (value == null) return false;
    return value.matches("^[a-zA-Z0-9_-]{3,20}$");
  }
}

// Kullanım
public record CreateUserDto(
    @ValidUsername String username,
    @NotBlank @Email String email
) {}

SQL Injection Önleme

Panache Active Record (Varsayılan Olarak Güvenli)

// İYİ: Panache ile parametreli sorgular
List<User> users = User.list("email = ?1 and active = ?2", email, true);

Optional<User> user = User.find("username", username).firstResultOptional();

// İYİ: İsimlendirilmiş parametreler
List<User> users = User.list("email = :email and age > :minAge",
    Parameters.with("email", email).and("minAge", 18));

Native Sorgular (Parametre Kullanın)

// KÖTÜ: String birleştirme
@Query(value = "SELECT * FROM users WHERE name = '" + name + "'", nativeQuery = true)

// İYİ: Parametreli native sorgu
@Entity
public class User extends PanacheEntity {
  public static List<User> findByEmailNative(String email) {
    return getEntityManager()
        .createNativeQuery("SELECT * FROM users WHERE email = :email", User.class)
        .setParameter("email", email)
        .getResultList();
  }
}

Parola Hash'leme

@ApplicationScoped
public class PasswordService {

  public String hash(String plainPassword) {
    return BcryptUtil.bcryptHash(plainPassword);
  }

  public boolean verify(String plainPassword, String hashedPassword) {
    return BcryptUtil.matches(plainPassword, hashedPassword);
  }
}

// Servis içinde
@ApplicationScoped
public class UserService {
  @Inject
  PasswordService passwordService;

  @Transactional
  public User register(CreateUserDto dto) {
    String hashedPassword = passwordService.hash(dto.password());
    User user = new User();
    user.email = dto.email();
    user.password = hashedPassword;
    user.persist();
    return user;
  }

  public boolean authenticate(String email, String password) {
    return User.find("email", email)
        .firstResultOptional()
        .map(u -> passwordService.verify(password, u.password))
        .orElse(false);
  }
}

CORS Yapılandırması

# application.properties
quarkus.http.cors=true
quarkus.http.cors.origins=https://app.example.com,https://admin.example.com
quarkus.http.cors.methods=GET,POST,PUT,DELETE
quarkus.http.cors.headers=accept,authorization,content-type,x-requested-with
quarkus.http.cors.exposed-headers=Content-Disposition
quarkus.http.cors.access-control-max-age=24H
quarkus.http.cors.access-control-allow-credentials=true

Gizli Bilgi Yönetimi

# application.properties - BURADA GİZLİ BİLGİ YOK

# Ortam değişkenlerini kullanın
quarkus.datasource.username=${DB_USER}
quarkus.datasource.password=${DB_PASSWORD}
quarkus.oidc.credentials.secret=${OIDC_CLIENT_SECRET}

# Or use Vault
quarkus.vault.url=https://vault.example.com
quarkus.vault.authentication.kubernetes.role=my-role

HashiCorp Vault Entegrasyonu

@ApplicationScoped
public class SecretService {

  @ConfigProperty(name = "api-key")
  String apiKey; // Vault'tan alınır

  public String getSecret(String key) {
    return ConfigProvider.getConfig().getValue(key, String.class);
  }
}

Rate Limiting (Hız Sınırlama)

Güvenlik Notu: X-Forwarded-For doğrudan kullanmayın — istemciler bunu taklit edebilir. Servlet request'ten gerçek uzak adresi veya kimliği doğrulanmış bir kimlik (API anahtarı, JWT subject) kullanın.

@ApplicationScoped
public class RateLimitFilter implements ContainerRequestFilter {
  private final Map<String, RateLimiter> limiters = new ConcurrentHashMap<>();

  @Inject
  HttpServletRequest servletRequest;

  @Override
  public void filter(ContainerRequestContext requestContext) {
    String clientId = getClientIdentifier();
    RateLimiter limiter = limiters.computeIfAbsent(clientId,
        k -> RateLimiter.create(100.0)); // Saniyede 100 istek

    if (!limiter.tryAcquire()) {
      requestContext.abortWith(
          Response.status(429)
              .entity(Map.of("error", "Too many requests"))
              .build()
      );
    }
  }

  private String getClientIdentifier() {
    // Konteyner tarafından sağlanan uzak adresi kullanın (X-Forwarded-For değil).
    // Güvenilir proxy arkasındaysanız quarkus.http.proxy.proxy-address-forwarding=true ayarlayın.
    return servletRequest.getRemoteAddr();
  }
}

Güvenlik Başlıkları

@Provider
public class SecurityHeadersFilter implements ContainerResponseFilter {

  @Override
  public void filter(ContainerRequestContext request, ContainerResponseContext response) {
    MultivaluedMap<String, Object> headers = response.getHeaders();

    // Clickjacking'i önle
    headers.putSingle("X-Frame-Options", "DENY");

    // XSS koruması
    headers.putSingle("X-Content-Type-Options", "nosniff");
    headers.putSingle("X-XSS-Protection", "1; mode=block");

    // HSTS
    headers.putSingle("Strict-Transport-Security", "max-age=31536000; includeSubDomains");

    // CSP — script-src için 'unsafe-inline' kullanmayın, XSS korumasını etkisiz kılar;
    // bunun yerine nonce veya hash kullanın
    headers.putSingle("Content-Security-Policy",
        "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'");
  }
}

Denetim Loglama

@ApplicationScoped
public class AuditService {
  private static final Logger LOG = Logger.getLogger(AuditService.class);

  @Inject
  SecurityIdentity securityIdentity;

  public void logAccess(String resource, String action) {
    String user = securityIdentity.isAnonymous()
        ? "anonymous"
        : securityIdentity.getPrincipal().getName();

    LOG.infof("AUDIT: user=%s action=%s resource=%s timestamp=%s",
        user, action, resource, Instant.now());
  }
}

// Resource içinde kullanım
@Path("/api/sensitive")
public class SensitiveResource {
  @Inject
  AuditService auditService;

  @GET
  @RolesAllowed("ADMIN")
  public Response getData() {
    auditService.logAccess("sensitive-data", "READ");
    return Response.ok(data).build();
  }
}
