   @EnableWebSecurity
   @EnableMethodSecurity(prePostEnabled = true)
   public class SecurityConfig {
   
       @Bean
       public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
           http

               .macAlgorithm(MacAlgorithm.HS256)
               .build();
       }
   }

3. Input Validation: Comprehensive validation with Bean Validation

   @Entity
   @Table(name = "order_processing_events")
   public class OrderProcessingEvent {
   
       @Id
       @GeneratedValue(strategy = GenerationType.UUID)
       private UUID id;
   
       @NotNull(message = "Order ID is required")
       @Column(name = "order_id", nullable = false)
       private UUID orderId;
   
       @NotBlank(message = "Event type is required")
       @Size(max = 100, message = "Event type must not exceed 100 characters")
       @Column(name = "event_type", nullable = false, length = 100)
       private String eventType;
   
       @NotNull(message = "Event status is required")
       @Enumerated(EnumType.STRING)
       @Column(name = "status", nullable = false)
       private EventStatus status;
   
       @Valid
       @JsonProperty("event_data")
       @Column(name = "event_data", columnDefinition = "jsonb")
       private Map<String, Object> eventData;
   }
   
   // Service-level validation
   @Service
   @Validated
   public class OrderProcessorService {
   
       public void processOrder(@Valid @NotNull OrderProcessingRequest request) {
           // Validate business rules
           if (!isValidOrderState(request.getOrderId())) {
               throw new InvalidOrderStateException("Order is not in a valid state for processing");
           }
   
           // Process with security context
           processOrderSecurely(request);
       }
   }

4. Secure Message Processing: Safe event handling

   @Component
   @RabbitListener(queues = "order.processing.queue")
   public class OrderEventProcessor {
   
       @Autowired
       private OrderProcessorService orderService;
   
       @Autowired
       private AuditService auditService;
   
       @RabbitHandler
       @Transactional
       public void processOrderEvent(@Valid @Payload OrderEvent event,
                                   @Header Map<String, Object> headers) {
   
           try {
               // Validate event source and authenticity
               validateEventSource(event, headers);
   
               // Log processing attempt
               auditService.logOrderProcessingAttempt(event);
   
               // Process event securely
               ProcessingResult result = orderService.processEvent(event);
   
               // Log processing result
               auditService.logOrderProcessingResult(event, result);
   
           } catch (SecurityException e) {
               log.error("Security violation in order processing: {}", e.getMessage());
               auditService.logSecurityViolation(event, e);
               throw e;
           } catch (Exception e) {
               log.error("Error processing order event: {}", e.getMessage());
               auditService.logProcessingError(event, e);
               throw new OrderProcessingException("Failed to process order event", e);
           }
       }
   
       private void validateEventSource(OrderEvent event, Map<String, Object> headers) {
           String signature = (String) headers.get("X-Event-Signature");
           if (!eventSignatureValidator.isValidSignature(event, signature)) {
               throw new SecurityException("Invalid event signature");
           }
       }
   }
