BUSINESS POSTURE

  • Business Priorities and Goals:

  • Rapid development of administrative interfaces for Laravel applications.

  • Simplified and user-friendly interface for managing application data and functionalities.

  • Reusable components and features to accelerate development workflows.

  • Extensibility and customization to adapt to specific project requirements.

  • Lowering the barrier to entry for building complex admin panels.

  • Business Risks:

  • Security vulnerabilities in generated admin panels due to misconfiguration or insecure coding practices by developers using Filament.

  • Dependency on the Filament project and its maintainers for ongoing support and security updates.

  • Potential for performance bottlenecks if Filament is not used efficiently or if the underlying Laravel application is not optimized.

  • Risk of data breaches if access control and data validation are not properly implemented in Filament-based admin panels.

  • Compatibility issues with future versions of Laravel or other dependencies, requiring maintenance and updates.

SECURITY POSTURE

  • Existing Security Controls:

  • security control: Laravel framework security features (CSRF protection, protection against SQL injection, etc.) - Implemented by Laravel framework.

  • security control: Authentication and authorization mechanisms provided by Laravel and Filament - Implemented within the application code and Filament framework.

  • security control: Input validation and sanitization practices within Laravel applications - Implemented by developers using Filament and Laravel features.

  • security control: Secure coding practices awareness among Laravel developers - Relies on developer training and best practices.

  • security control: Dependency management using Composer to manage and update PHP packages - Implemented using Composer tool.

  • security control: Version control system (Git) for code management and tracking changes - Implemented using Git and GitHub.

  • Accepted Risks:

  • accepted risk: Security vulnerabilities in third-party packages used by Filament and Laravel - Mitigated by regular dependency updates and security audits.

  • accepted risk: Misconfiguration of server environment leading to security issues - Mitigated by following security best practices for server configuration.

  • accepted risk: Human error in development and deployment leading to security vulnerabilities - Mitigated by code reviews, testing, and automation.

  • accepted risk: Open-source nature of Filament means vulnerabilities might be publicly disclosed before patches are available - Mitigated by active community and prompt security response from maintainers.

  • Recommended Security Controls:

  • security control: Implement automated security scanning (SAST/DAST) in the development pipeline to identify potential vulnerabilities early.

  • security control: Conduct regular security audits and penetration testing of Filament-based applications to identify and address security weaknesses.

  • security control: Enforce strong password policies and multi-factor authentication for administrative users.

  • security control: Implement rate limiting and brute-force protection for login endpoints.

  • security control: Regularly update Filament and Laravel dependencies to patch known security vulnerabilities.

  • security control: Provide security training for developers using Filament to promote secure coding practices.

  • Security Requirements:

  • Authentication:

  • Requirement: Secure authentication mechanism for administrative users.

  • Requirement: Support for strong password policies (complexity, rotation, lockout).

  • Requirement: Option for multi-factor authentication (MFA) for enhanced security.

  • Requirement: Protection against brute-force attacks on login endpoints.

  • Authorization:

  • Requirement: Role-based access control (RBAC) to manage user permissions and access to different features and data.

  • Requirement: Granular permission management to control access at the resource level.

  • Requirement: Secure session management to prevent session hijacking.

  • Requirement: Principle of least privilege should be applied to user roles and permissions.

  • Input Validation:

  • Requirement: Comprehensive input validation for all user inputs to prevent injection attacks (SQL injection, XSS, etc.).

  • Requirement: Server-side validation should be enforced for all critical data inputs.

  • Requirement: Proper sanitization and encoding of user inputs before displaying or storing them.

  • Requirement: Protection against mass assignment vulnerabilities.

  • Cryptography:

  • Requirement: Secure storage of sensitive data (passwords, API keys, etc.) using strong encryption algorithms.

  • Requirement: Use of HTTPS for all communication to protect data in transit.

  • Requirement: Secure generation and management of cryptographic keys.

  • Requirement: Protection of sensitive data at rest and in transit.

RISK ASSESSMENT

  • Critical Business Processes:

  • User management (creating, updating, deleting admin users).

  • Data management (creating, reading, updating, deleting application data through the admin panel).

  • System configuration management (managing application settings and parameters).

  • Access control management (defining roles and permissions for admin users).

  • Data Sensitivity:

  • User credentials (passwords, API keys) - Highly sensitive, require strong encryption and access control.

  • Application data (depending on the application domain) - Sensitivity varies, may include personally identifiable information (PII), financial data, or confidential business information. Requires appropriate data protection measures based on sensitivity.

  • System configuration data - Potentially sensitive, may contain secrets or configuration details that could be exploited if exposed. Requires secure storage and access control.

  • Audit logs - Sensitive, contain records of user activities and system events, important for security monitoring and incident response. Requires secure storage and access control.

QUESTIONS & ASSUMPTIONS

  • Questions:

  • What is the specific sensitivity level of the data managed by the Filament Admin Panel?

  • What are the compliance requirements (e.g., GDPR, HIPAA, PCI DSS) that the application needs to adhere to?

  • What is the organization's risk appetite regarding security vulnerabilities?

  • Are there any specific security tools or technologies already in use within the organization that should be integrated?

  • What is the expected user base and traffic volume for the application?

  • Assumptions:

  • The target environment is a cloud-based infrastructure.

  • Security is a high priority for the project.

  • The organization has a development team familiar with Laravel and PHP.

  • Standard web application security best practices are applicable.

  • The application will handle some level of sensitive data, requiring appropriate security measures.

  • The organization is looking for a comprehensive design document that can be used for threat modeling and security planning.
