BUSINESS POSTURE

  • Business Priorities and Goals:
    • Provide a stable, productive, and performant JavaScript framework for building ambitious web applications.
    • Foster a vibrant and supportive community of developers around the framework.
    • Ensure the long-term maintainability and evolution of the framework.
    • Promote best practices in web application development.
  • Business Risks:
    • Security vulnerabilities in the framework could negatively impact applications built with Ember.js and damage the framework's reputation.
    • Lack of community support or contributions could hinder the framework's growth and maintenance.
    • Breaking changes or instability could discourage adoption and developer satisfaction.
    • Competition from other JavaScript frameworks could reduce Ember.js's market share.

SECURITY POSTURE

  • Existing Security Controls:
    • security control: Code reviews by core team members and community contributors (described in project contribution guidelines).
    • security control: Public issue tracker for reporting bugs and vulnerabilities (GitHub issues).
    • security control: Reliance on community security researchers for vulnerability discovery.
    • security control: Regular updates and releases to address reported issues (release cycle documentation).
  • Accepted Risks:
    • accepted risk: Potential for undiscovered vulnerabilities due to the complexity of the framework and reliance on community contributions.
    • accepted risk: Dependency on third-party libraries (npm packages) which may introduce vulnerabilities.
    • accepted risk: Security of applications built with Ember.js is ultimately the responsibility of the application developers.
  • Recommended Security Controls:
    • security control: Implement automated security scanning (SAST/DAST) in the CI/CD pipeline for the framework itself.
    • security control: Establish a formal vulnerability disclosure and response process with a dedicated security team or point of contact.
    • security control: Conduct periodic security audits by external security experts.
    • security control: Improve dependency management practices, including vulnerability scanning of dependencies and dependency pinning.
    • security control: Provide security guidelines and best practices for developers building applications with Ember.js in the official documentation.
  • Security Requirements:
    • Authentication:
      • Ember.js itself does not handle backend authentication. Applications built with Ember.js will need to implement authentication mechanisms, typically interacting with backend APIs. Security requirements for authentication should be considered in the context of applications built with Ember.js, not the framework itself.
    • Authorization:
      • Ember.js provides mechanisms for client-side routing and component rendering, which can be used to implement client-side authorization within applications. Applications should enforce authorization logic both on the client-side (for user interface control) and server-side (for API access control).
    • Input Validation:
      • Ember.js applications need to perform input validation to prevent vulnerabilities like Cross-Site Scripting (XSS) and injection attacks. Input validation should be implemented in application code, especially when handling user input and data from external sources.
    • Cryptography:
      • Ember.js itself does not provide built-in cryptographic functions. If applications require cryptography, they should use standard JavaScript cryptography libraries. Secure key management and proper implementation of cryptographic algorithms are crucial security requirements for applications using cryptography.

DEPLOYMENT

  • Deployment Options:

    • Static Website Hosting (e.g., Netlify, Vercel, AWS S3, GitHub Pages): Ember.js applications are typically built into static assets (HTML, CSS, JavaScript) and can be deployed to static website hosting platforms or CDNs.
    • Web Servers (e.g., Nginx, Apache): Static assets can be served from traditional web servers.
    • Server-Side Rendering (SSR) (with Node.js): For improved SEO and performance, Ember.js applications can be rendered on the server-side using Node.js before being sent to the browser. This adds a Node.js server component to the deployment.

  • Build Process Description:

    • Developer writes code and commits changes to a code repository (e.g., GitHub).
    • CI/CD system (e.g., GitHub Actions) is triggered by code changes.
    • CI/CD system fetches dependencies using a package manager (npm or yarn).
    • Build tools (Ember CLI) are used to compile and build the Ember.js application.
    • Linters and SAST (Static Application Security Testing) tools are run to identify code quality issues and potential security vulnerabilities.
    • Unit and integration tests are executed to ensure code functionality and stability.
    • Build artifacts (static assets like HTML, CSS, JavaScript files) are generated.
    • Build artifacts are published to a package registry or CDN for deployment.

  • Build Process Security Controls:

    • security control: Secure code repository (access control, branch protection).
    • security control: Secure CI/CD pipeline configuration (least privilege, secrets management).
    • security control: Dependency vulnerability scanning during build process.
    • security control: Use of linters and SAST tools to identify and remediate code quality and security issues.
    • security control: Automated unit and integration testing to ensure code reliability and catch regressions.
    • security control: Code signing or artifact signing to ensure integrity of build artifacts.
    • security control: Access control to package registry/CDN to prevent unauthorized modifications.

RISK ASSESSMENT

  • Critical Business Processes:
    • Maintaining the stability, security, and usability of the Ember.js framework.
    • Ensuring the continued adoption and growth of the Ember.js ecosystem.
    • Providing a reliable platform for developers to build and deploy web applications.
  • Data to Protect:
    • Ember.js source code (intellectual property, integrity).
    • Ember.js releases and build artifacts (integrity, availability).
    • Community contributions and issue reports (integrity, availability).
  • Data Sensitivity:
    • Ember.js source code: High sensitivity (publicly available but integrity is critical).
    • Ember.js releases and build artifacts: High sensitivity (integrity and availability are critical for users).
    • Community contributions and issue reports: Medium sensitivity (publicly accessible, but integrity and availability are important for community engagement).
