Mitigation Strategy: Secure Helidon Configuration using Helidon Configuration API

  • Description:

    1. Identify Sensitive Configuration: Determine configuration properties containing sensitive information (credentials, API keys, etc.).
    2. Externalize Configuration using Helidon Config Sources: Utilize Helidon's configuration API and built-in or custom ConfigSource implementations to load sensitive data from external sources like environment variables, files outside the application package, or configuration servers.
    3. Use Helidon Configuration Overrides: Leverage Helidon's configuration override mechanisms to manage environment-specific configurations without modifying base configurations, ensuring consistency and security across deployments.
    4. Implement Configuration Validation with Helidon Config API: Use Helidon's Config API to programmatically access and validate configuration values at application startup, ensuring critical settings are correctly configured before the application starts serving requests. Fail fast with informative errors if validation fails.

    • Threats Mitigated:

      • Exposure of Sensitive Data in Code/Repositories (High Severity): Prevents hardcoding secrets in application code or configuration files within the application package, reducing the risk of accidental exposure in version control or during deployment.
      • Misconfiguration Vulnerabilities (Medium Severity): Catches configuration errors early at startup, preventing the application from running with insecure or incomplete settings that could lead to vulnerabilities.

    • Impact:

      • Exposure of Sensitive Data: High Risk Reduction - Significantly reduces the risk of secrets exposure by promoting externalization and secure handling.
      • Misconfiguration Vulnerabilities: Medium Risk Reduction - Reduces the risk of vulnerabilities arising from misconfiguration by enforcing validation at startup.

    • Currently Implemented:

      • Partially implemented. Helidon's Config API is used for loading some configurations, but not consistently for all sensitive data.
      • Configuration validation using Helidon's API is basic and not comprehensive.

    • Missing Implementation:

      • Full adoption of Helidon ConfigSource for externalizing all sensitive configurations.
      • Comprehensive configuration validation using Helidon's Config API for all critical settings.
      • Leveraging Helidon's configuration override features more extensively for environment-specific configurations.

Mitigation Strategy: Strengthen MicroProfile Security Implementations within Helidon

  • Description:

    1. Configure Authentication Mechanisms in Helidon Security: Utilize Helidon's MicroProfile Security integration to configure authentication mechanisms like JWT-based authentication, Basic Authentication, or custom authentication providers. Configure these mechanisms through Helidon's security configuration.
    2. Define Authorization Policies using MicroProfile Security Annotations: Employ MicroProfile Security annotations (@RolesAllowed, @PermitAll, @DenyAll) provided by Helidon's MicroProfile implementation to define and enforce authorization policies directly within your JAX-RS resources or CDI beans.
    3. Secure JWT Validation in Helidon: When using JWT authentication, ensure proper configuration of JWT validation within Helidon, including signature verification, issuer validation, audience checks, and handling of token expiration. Utilize Helidon's JWT security features for robust validation.
    4. Leverage Helidon Security Providers: Explore and utilize Helidon's built-in security providers or implement custom SecurityProvider implementations to integrate with specific authentication and authorization systems, tailoring security to your application's needs within the Helidon framework.

    • Threats Mitigated:

      • Unauthorized Access (High Severity): Prevents unauthorized users from accessing protected resources and functionalities by enforcing authentication and authorization policies defined using Helidon's MicroProfile Security features.
      • Data Breaches (High Severity): Reduces the risk of data breaches by controlling access to sensitive data based on user roles and permissions managed through Helidon's security framework.
      • Privilege Escalation (Medium Severity): Prevents users from gaining unauthorized access to resources or functionalities beyond their assigned roles, enforced by Helidon's authorization mechanisms.

    • Impact:

      • Unauthorized Access: High Risk Reduction - Significantly reduces the risk of unauthorized access by leveraging Helidon's security features.
      • Data Breaches: High Risk Reduction - Significantly reduces the risk of data breaches due to unauthorized access, controlled by Helidon's security framework.
      • Privilege Escalation: Medium Risk Reduction - Reduces the risk of privilege escalation by enforcing authorization policies within Helidon.

    • Currently Implemented:

      • Partially implemented. MicroProfile Security annotations are used in some JAX-RS resources, but not consistently across the application.
      • JWT authentication is configured in Helidon for specific endpoints, but JWT validation might not be fully robust.

    • Missing Implementation:

      • Consistent and comprehensive application of MicroProfile Security annotations across all protected resources.
      • Robust JWT validation configuration within Helidon, covering all necessary checks.
      • Centralized definition and management of security roles and permissions within Helidon's security configuration.
      • Exploration and potential utilization of custom Helidon SecurityProvider implementations for specific security needs.

Mitigation Strategy: Configure Secure Logging within Helidon

  • Description:

    1. Utilize Helidon Logging Framework for Security Events: Leverage Helidon's built-in logging framework (Log4j 2 integration) to log security-relevant events within the application. Configure loggers specifically for security components.
    2. Configure Helidon Log Output Destinations: Configure Helidon's logging framework to direct security logs to secure and appropriate destinations, such as dedicated log files with restricted access, or centralized logging systems.
    3. Customize Helidon Log Format for Security Context: Customize the log format within Helidon's logging configuration to include relevant security context in log messages, such as timestamps, user identifiers (if available), source IP addresses, and request details.
    4. Filter Sensitive Data in Helidon Logging: Configure Helidon's logging framework to filter or mask sensitive data before it is written to logs, preventing accidental logging of passwords, API keys, or PII.

    • Threats Mitigated:

      • Delayed Incident Detection (Medium Severity): Improves incident detection by providing audit trails of security-related events captured through Helidon's logging framework.
      • Insufficient Forensic Information (Medium Severity): Provides valuable information for post-incident analysis and forensic investigations by logging detailed security context using Helidon's logging capabilities.
      • Exposure of Sensitive Data in Logs (High Severity): Prevents accidental exposure of sensitive information in log files by configuring filtering and masking within Helidon's logging framework.

    • Impact:
