BUSINESS POSTURE

This project, uni-app, aims to provide a unified development framework for building applications across multiple platforms including iOS, Android, Web, and various mini-program environments using Vue.js.

  • Business Priorities and Goals:

    • Cross-platform compatibility: Enable developers to write code once and deploy to multiple platforms, reducing development time and cost.
    • Developer productivity: Offer a familiar and efficient development experience based on Vue.js.
    • Performance: Ensure applications built with uni-app perform well on target platforms.
    • Community growth: Foster a strong developer community around uni-app to drive adoption and contribution.
    • Ease of use: Provide a simple and intuitive framework for developers of varying skill levels.

  • Business Risks:

    • Security vulnerabilities in the uni-app framework could impact all applications built using it, leading to widespread security incidents.
    • Lack of timely security updates and patches could leave applications vulnerable to known exploits.
    • Dependence on third-party libraries and components introduces supply chain risks.
    • Poorly designed or implemented security features in uni-app could lead to insecure applications.
    • Reputational damage if applications built with uni-app are frequently compromised.

SECURITY POSTURE

  • Existing Security Controls:

    • security control: GitHub repository for source code management and version control. Implemented in: https://github.com/dcloudio/uni-app
    • security control: Issue tracking system on GitHub for reporting and managing bugs and feature requests, including potential security vulnerabilities. Implemented in: https://github.com/dcloudio/uni-app/issues
    • security control: Community contributions and code reviews through pull requests on GitHub. Implemented in: GitHub Pull Request process.
    • security control: Documentation available online, potentially including some security considerations. Implemented in: https://uniapp.dcloud.net.cn/ (Documentation website)

  • Accepted Risks:

    • accepted risk: Open-source nature implies vulnerabilities might be publicly disclosed before a patch is available.
    • accepted risk: Reliance on community contributions for security improvements and vulnerability identification.
    • accepted risk: Potential for vulnerabilities in third-party dependencies.

  • Recommended Security Controls:

    • security control: Implement automated security scanning tools (SAST, DAST, dependency scanning) in the CI/CD pipeline to identify vulnerabilities early in the development process.
    • security control: Establish a clear vulnerability disclosure policy and process to handle security reports effectively.
    • security control: Conduct regular security audits and penetration testing to proactively identify and address security weaknesses.
    • security control: Implement a Security Champions program to promote security awareness and best practices within the development team.
    • security control: Enhance input validation and output encoding mechanisms within the framework to prevent common web vulnerabilities.
    • security control: Provide secure coding guidelines and security training for developers using uni-app.

  • Security Requirements:

    • Authentication:
      • Requirement: If uni-app framework includes any backend or administrative functionalities, it must implement secure authentication mechanisms to verify user identity.
      • Requirement: Applications built with uni-app should provide guidance and best practices for implementing secure authentication based on the specific needs of the application.
    • Authorization:
      • Requirement: If uni-app framework includes any backend or administrative functionalities, it must implement robust authorization mechanisms to control access to resources and functionalities based on user roles and permissions.
      • Requirement: Applications built with uni-app should provide guidance and best practices for implementing secure authorization to manage user access within the application.
    • Input Validation:
      • Requirement: The uni-app framework must provide mechanisms and guidance to developers for validating user inputs to prevent injection attacks (e.g., XSS, SQL injection).
      • Requirement: Input validation should be applied on both client-side and server-side (if applicable) to ensure comprehensive protection.
    • Cryptography:
      • Requirement: If uni-app framework handles sensitive data, it must provide secure cryptographic functionalities for data encryption in transit and at rest.
      • Requirement: Applications built with uni-app should provide guidance and best practices for using cryptography to protect sensitive user data.

RISK ASSESSMENT

  • Critical Business Processes:

    • Development and maintenance of the uni-app framework.
    • Distribution of the uni-app framework to developers.
    • Building and deployment of applications by developers using uni-app.

  • Data to Protect and Sensitivity:

    • Source code of uni-app framework: Highly sensitive, intellectual property, confidentiality and integrity are critical.
    • Build artifacts (packages): Sensitive, integrity is critical to prevent supply chain attacks.
    • Developer credentials (indirectly, access to GitHub, package registry): Highly sensitive, confidentiality and integrity are critical.
    • User data within applications built using uni-app (indirectly): Sensitivity depends on the application, confidentiality, integrity, and availability are important.
