This document outlines the security considerations, current implementation status, and recommendations for the Franchises API project.

❌ NO AUTHENTICATION IMPLEMENTED

This API currently does not implement any authentication or authorization mechanisms. All endpoints are publicly accessible without any form of user verification.

Implications:

• Any client can access all API endpoints
• No user identity verification
• No role-based access control
• No API key or token validation
• All CRUD operations are unrestricted

Recommendation for Production:

// Example: Add Spring Security dependency
implementation("org.springframework.boot:spring-boot-starter-security")
implementation("org.springframework.boot:spring-boot-starter-oauth2-resource-server")

✅ BASIC VALIDATION IMPLEMENTED

• Input validation using Spring Boot validation annotations
• Request body validation for required fields
• Data type validation (String, Int, etc.)
• MongoDB schema validation through domain models

✅ CORS ENABLED

// Current CORS configuration allows all origins
@CrossOrigin(origins = ["*"])

Security Concern: Wildcard CORS policy allows requests from any domain.

Recommendation:

// Restrict to specific domains in production
@CrossOrigin(origins = ["https://yourdomain.com", "https://app.yourdomain.com"])

⚠️ BASIC MONGODB SETUP

• No MongoDB authentication configured
• Default connection without credentials
• No encryption at rest configured
• No connection encryption (TLS/SSL)

Current Configuration:

spring.data.mongodb.uri=mongodb://localhost:27017/franchisesdb

Recommended Production Configuration:

spring.data.mongodb.uri=mongodb://username:password@localhost:27017/franchisesdb?ssl=true&authSource=admin

✅ SECURE ERROR RESPONSES

• No sensitive information exposed in error messages
• Standardized error response format
• Proper HTTP status codes
• No stack traces exposed to clients

✅ AUTOMATED SECURITY SCANNING

• GitHub Actions workflow includes security vulnerability scanning
• Automated dependency vulnerability detection
• Regular security updates through CI/CD pipeline

# .github/workflows/ci.yml
- name: Run security scan
  run: ./gradlew dependencyCheckAnalyze

1. Implement Authentication

   // Add JWT or OAuth2 authentication
   @EnableWebFluxSecurity
   class SecurityConfig {
       @Bean
       fun securityWebFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain {
           return http
               .authorizeExchange { exchanges ->
                   exchanges
                       .pathMatchers("/swagger-ui/**", "/v3/api-docs/**").permitAll()
                       .anyExchange().authenticated()
               }
               .oauth2ResourceServer { oauth2 -> oauth2.jwt() }
               .build()
       }
   }

2. Secure MongoDB Connection

   # Use environment variables for credentials
   spring.data.mongodb.uri=${MONGODB_URI}
   spring.data.mongodb.username=${MONGODB_USERNAME}
   spring.data.mongodb.password=${MONGODB_PASSWORD}

3. Restrict CORS Origins

   @CrossOrigin(origins = ["\${app.cors.allowed-origins}"])

4. Add Rate Limiting

   // Implement rate limiting to prevent abuse
   @Component
   class RateLimitingFilter : WebFilter {
       // Rate limiting implementation
   }

5. Input Sanitization

   // Add comprehensive input validation
   data class CreateFranchiseRequest(
       @field:NotBlank(message = "Name is required")
       @field:Size(max = 100, message = "Name must not exceed 100 characters")
       @field:Pattern(regexp = "^[a-zA-Z0-9\\s]+$", message = "Name contains invalid characters")
       val name: String
   )

• ✅ Current configuration is acceptable
• ✅ Open access for testing purposes
• ✅ Local MongoDB without authentication

• ❌ REQUIRES IMMEDIATE SECURITY IMPLEMENTATION
• 🔒 Authentication and authorization mandatory
• 🔒 Encrypted database connections required
• 🔒 Restricted CORS origins
• 🔒 API rate limiting
• 🔒 Security headers implementation

Recommended Security Headers:

@Configuration
class SecurityHeadersConfig {
    @Bean
    fun securityHeaders(): WebFilter {
        return WebFilter { exchange, chain ->
            exchange.response.headers.apply {
                set("X-Content-Type-Options", "nosniff")
                set("X-Frame-Options", "DENY")
                set("X-XSS-Protection", "1; mode=block")
                set("Strict-Transport-Security", "max-age=31536000; includeSubDomains")
                set("Content-Security-Policy", "default-src 'self'")
            }
            chain.filter(exchange)
        }
    }
}
