Okay, let's create a design document for the laravel-admin project.

BUSINESS POSTURE

Business Priorities and Goals:

  • Provide a fast and efficient way to build administration interfaces for Laravel applications.
  • Reduce development time and cost associated with creating admin panels.
  • Offer a customizable and extensible platform to meet diverse administrative needs.
  • Provide a user-friendly interface for managing application data and functionality.
  • Maintain a good level of security to protect sensitive data and prevent unauthorized access.

Most Important Business Risks:

  • Unauthorized access to sensitive data or functionality through the admin interface.
  • Data breaches or leaks due to vulnerabilities in the laravel-admin package or its dependencies.
  • Disruption of service due to misconfiguration or exploitation of vulnerabilities.
  • Reputational damage due to security incidents.
  • Compliance violations related to data privacy and security.
  • Supply chain attacks through compromised dependencies.

SECURITY POSTURE

Existing Security Controls:

  • security control: Authentication: Laravel's built-in authentication system is used to manage user logins and access control. (Described in Laravel documentation and laravel-admin documentation).
  • security control: Authorization: laravel-admin provides role-based access control (RBAC) features to restrict access to specific resources and actions based on user roles. (Described in laravel-admin documentation).
  • security control: Input Validation: Laravel's validation features are used to validate user input and prevent common web vulnerabilities like cross-site scripting (XSS) and SQL injection. (Described in Laravel documentation and used throughout laravel-admin code).
  • security control: CSRF Protection: Laravel's built-in CSRF protection is used to prevent cross-site request forgery attacks. (Described in Laravel documentation and enabled by default).
  • security control: Encryption: Laravel's encryption features are used to protect sensitive data at rest and in transit. (Described in Laravel documentation).
  • security control: Database Security: Relies on Laravel's database security best practices, including parameterized queries or ORM usage to prevent SQL injection. (Described in Laravel documentation).

Accepted Risks:

  • accepted risk: The security of the laravel-admin interface is highly dependent on the secure configuration and implementation by the developers using the package.
  • accepted risk: Dependencies on third-party packages introduce potential supply chain risks.
  • accepted risk: The default configuration may not be suitable for all environments and requires careful review and customization.

Recommended Security Controls:

  • security control: Implement regular security audits and penetration testing of applications using laravel-admin.
  • security control: Enforce strong password policies and multi-factor authentication (MFA).
  • security control: Implement comprehensive logging and monitoring to detect and respond to security incidents.
  • security control: Keep laravel-admin and all its dependencies up to date with the latest security patches.
  • security control: Implement a robust vulnerability management program.
  • security control: Use a Content Security Policy (CSP) to mitigate XSS attacks.
  • security control: Implement strict file upload validation to prevent malicious file uploads.
  • security control: Regularly review and update the RBAC configuration to ensure least privilege.

Security Requirements:

  • Authentication:

    • All users must be authenticated before accessing the admin interface.
    • Support for multi-factor authentication should be considered.
    • Strong password policies must be enforced.
    • Session management must be secure, with appropriate timeouts and protection against session hijacking.

  • Authorization:

    • Access to resources and actions must be controlled based on user roles and permissions.
    • The principle of least privilege must be applied.
    • Regular review and auditing of user roles and permissions are required.

  • Input Validation:

    • All user input must be validated to prevent common web vulnerabilities.
    • Validation rules must be strict and specific to the expected data type.
    • Output encoding should be used to prevent XSS.

  • Cryptography:

    • Sensitive data must be encrypted at rest and in transit.
    • Strong, industry-standard cryptographic algorithms must be used.
    • Key management must be secure.

Build Process Description:

  1. Developer commits and pushes code changes to the Git repository (GitHub).
  2. A CI/CD pipeline (e.g., GitHub Actions, Jenkins) is triggered by the push event.
  3. The pipeline runs a linter to check code style and potential errors.
  4. The pipeline runs unit and integration tests.
  5. The pipeline runs a Static Application Security Testing (SAST) scanner to identify potential security vulnerabilities in the code.
  6. If all checks pass, the pipeline builds a Docker image for the application.
  7. The Docker image is pushed to an image registry (e.g., Docker Hub, Amazon ECR).

Security Controls:

  • security control: Code review: All code changes should be reviewed by another developer before merging.
  • security control: Linting: Use a linter to enforce code style and identify potential errors.
  • security control: Automated testing: Implement comprehensive unit and integration tests to ensure code quality and prevent regressions.
  • security control: SAST scanning: Use a SAST scanner to identify potential security vulnerabilities in the code.
  • security control: Dependency scanning: Scan dependencies for known vulnerabilities.
  • security control: Image signing: Sign Docker images to ensure their integrity and authenticity.
  • security control: Least privilege: The CI/CD pipeline should have only the necessary permissions to perform its tasks.

RISK ASSESSMENT

Critical Business Processes:

  • User authentication and authorization.
  • Data management (CRUD operations) through the admin interface.
  • Application configuration and management.
  • Email sending (if applicable).

Data Sensitivity:

  • User data (usernames, passwords, roles, permissions, potentially PII). Sensitivity: High
  • Application data (depends on the specific application, could range from low to high sensitivity).
  • Configuration data (database credentials, API keys). Sensitivity: High

QUESTIONS & ASSUMPTIONS

Questions:

  • What specific types of data will be managed through the laravel-admin interface?
  • Are there any specific compliance requirements (e.g., GDPR, HIPAA) that need to be considered?
  • What is the expected user base size and growth rate?
  • What is the existing infrastructure and deployment environment?
  • Are there any existing security policies or guidelines that need to be followed?
  • What level of logging and monitoring is currently in place?
  • What is the process for managing and updating dependencies?

Assumptions:

  • BUSINESS POSTURE: The organization has a moderate risk appetite and prioritizes security but also needs a rapid development cycle.
  • SECURITY POSTURE: The development team has basic knowledge of secure coding practices. Laravel's built-in security features are utilized but may not be fully configured or optimized.
  • DESIGN: The application uses a standard Laravel architecture with a relational database. The deployment environment is likely cloud-based or containerized. The build process is automated using a CI/CD pipeline.
