This document provides comprehensive security guidelines for implementing and deploying the Oracle Fusion + MuleSoft integration patterns safely. Following these guidelines ensures your integration maintains enterprise-grade security standards.

❌ DON'T:

oracle:
  fusion:
    username: "actual_username"
    password: "actual_password"
    client_secret: "real_client_secret"

✅ DO:

oracle:
  fusion:
    username: "${oracle.fusion.username}"
    password: "${secure::oracle.fusion.password}"
    client_secret: "${secure::oracle.fusion.client.secret}"

Use environment variables or secure property files:

# Environment variables
export ORACLE_FUSION_USERNAME="your_username"
export ORACLE_FUSION_PASSWORD="your_password"

# Or use MuleSoft secure properties
mvn mule:encrypt -Dpassword=your_key -Dvalue=your_secret

• Use CloudHub Secure Properties for cloud deployments
• Use Hardware Security Modules (HSM) for on-premise deployments
• Implement secret rotation policies

• Store tokens in ObjectStore with appropriate TTL
• Never log tokens in plain text
• Implement token refresh before expiration

<!-- Example: Secure SAML configuration -->
<saml2:Assertion>
  <saml2:Conditions NotBefore="..." NotOnOrAfter="...">
    <saml2:AudienceRestriction>
      <saml2:Audience>your-oracle-instance.oraclecloud.com</saml2:Audience>
    </saml2:AudienceRestriction>
  </saml2:Conditions>
</saml2:Assertion>

• Use strong signing keys (minimum 256-bit)
• Validate JWT expiration and audience
• Implement proper JWT verification

http:
  listener:
    protocol: "HTTPS"
    tls:
      enabled: true
      keyStore: "${secure::keystore.path}"
      keyStorePassword: "${secure::keystore.password}"

• Implement Rate Limiting
• Use Client ID Enforcement
• Enable IP Whitelisting for production
• Configure CORS appropriately

• Authentication attempts (success/failure)
• API access patterns
• Error conditions
• Performance metrics

// ❌ DON'T log sensitive data
logger.info("User login: " + username + " with password: " + password);

// ✅ DO log safely
logger.info("Authentication attempt for user: " + username + " - " + (success ? "SUCCESS" : "FAILED"));

<!-- Mask sensitive fields in logs -->
<PatternLayout>
  <Pattern>%d{ISO8601} [%thread] %-5level [%X{correlationId}] %logger{36} - %msg%n</Pattern>
</PatternLayout>

Production   ← Use separate Oracle instances
    ↓
Testing      ← Use test data and mock services
    ↓  
Development  ← Use local mock servers

# Use non-root user
FROM mulesoft/mule:4.9.0
USER mule

# Remove unnecessary packages
RUN apt-get remove -y curl wget

# Use generic placeholders
oracle:
  fusion:
    base:
      url: "https://your-oracle-instance.oraclecloud.com"
    auth:
      username: "${oracle.fusion.username}"

# Use secure property references
oracle:
  fusion:
    base:
      url: "${oracle.fusion.base.url}"
    auth:
      username: "${secure::oracle.fusion.username}"
      password: "${secure::oracle.fusion.password}"

# Encrypt sensitive values
mvn mule:encrypt -Dprop.key=your_encryption_key -Dprop.value=sensitive_value

# Result: ![encrypted_value]
# Use in configuration: password: "![encrypted_value]"

• Authentication Tests

  • Invalid credentials rejected
  • Token expiration handled
  • Rate limiting enforced

• Authorization Tests

  • Role-based access working
  • Resource-level permissions
  • API endpoint restrictions

• Input Validation Tests

  • SQL injection prevention
  • XSS protection
  • Input sanitization

• Data Protection Tests

  • Encryption in transit
  • Encryption at rest
  • PII data masking

# Alert on suspicious patterns
monitoring:
  alerts:
    - name: "High Authentication Failures"
      condition: "auth_failures > 10 per minute"
      action: "notify_security_team"
    
    - name: "Unusual API Access Patterns"
      condition: "requests > 1000 per minute"
      action: "enable_rate_limiting"

1. Immediate: Revoke compromised credentials
2. Short-term: Rotate all related secrets
3. Long-term: Review and strengthen security measures

• Review access logs for anomalies
• Check for failed authentication attempts
• Monitor API usage patterns

• Update dependencies with security patches
• Review and rotate non-critical secrets
• Conduct security training for team

• Perform penetration testing
• Review and update security policies
• Audit user access permissions

<!-- Keep dependencies up to date -->
<properties>
  <jackson.version>2.16.1</jackson.version> <!-- Latest secure version -->
  <commons.lang.version>3.14.0</commons.lang.version>
</properties>

1. Injection - Use parameterized queries and input validation
2. Broken Authentication - Implement proper token management
3. Sensitive Data Exposure - Encrypt all sensitive data
4. XML External Entities (XXE) - Disable external entity processing
5. Broken Access Control - Implement role-based access
6. Security Misconfiguration - Follow secure configuration guidelines
7. Cross-Site Scripting (XSS) - Sanitize all user inputs
8. Insecure Deserialization - Validate serialized objects
9. Using Components with Known Vulnerabilities - Regular dependency updates
10. Insufficient Logging & Monitoring - Implement comprehensive logging

• Implement data minimization
• Provide data access and deletion capabilities
• Maintain audit trails for data processing
