BUSINESS POSTURE

  • Business priorities and goals
    • Simplify development of iOS applications using reactive programming principles.
    • Provide reusable and efficient data source implementations for UITableView and UICollectionView.
    • Improve developer productivity by reducing boilerplate code for data management in lists and grids.
    • Enable more maintainable and testable codebases in iOS projects.
  • Business risks
    • Security vulnerabilities in the library could be inherited by applications that depend on it, potentially leading to data breaches or application instability.
    • Lack of active maintenance or community support could lead to unaddressed security issues and compatibility problems in the future.
    • Dependency on RxSwift framework introduces a transitive dependency risk, where vulnerabilities in RxSwift could also impact applications using rxdatasources.

SECURITY POSTURE

  • Existing security controls
    • security control: Open source development model, which allows for community review and contribution. Implemented on GitHub.
    • security control: Publicly accessible codebase, enabling transparency and external security audits. Implemented on GitHub.
    • accepted risk: Reliance on community contributions for security vulnerability identification and patching.
    • accepted risk: Lack of formal security audits or penetration testing.
    • accepted risk: Potential for vulnerabilities to be introduced by contributors.
  • Recommended security controls
    • security control: Implement automated static code analysis (SAST) in the CI/CD pipeline to detect potential code-level vulnerabilities.
    • security control: Integrate dependency scanning to identify known vulnerabilities in RxSwift and other dependencies.
    • security control: Establish a process for reporting and handling security vulnerabilities, including a security policy and contact information.
    • security control: Consider code signing for releases to ensure integrity and authenticity of the library.
  • Security requirements
    • Authentication: Not applicable, as the library itself does not handle authentication. Applications using the library will be responsible for their own authentication mechanisms.
    • Authorization: Not applicable, as the library itself does not handle authorization. Applications using the library will be responsible for their own authorization mechanisms.
    • Input validation: The library should handle data provided to data sources robustly, validating inputs to prevent unexpected behavior or crashes. Input validation should be implemented within the library's data processing logic.
    • Cryptography: Not directly applicable, as the library is focused on data presentation. If applications using the library handle sensitive data, they are responsible for implementing appropriate encryption and decryption mechanisms outside of the library's scope.

RISK ASSESSMENT

  • Critical business process: Development of iOS applications that rely on efficient and maintainable data presentation in lists and grids. Disruption or compromise of the rxdatasources library could impact the development and security of these applications.
  • Data to protect:
    • Source code of the rxdatasources library: Sensitivity is high, as unauthorized access or modification could lead to vulnerabilities being introduced or intellectual property theft.
    • Integrity of published packages: Sensitivity is high, as compromised packages could be distributed to developers, leading to widespread vulnerabilities in applications using the library.
    • Indirectly, data handled by applications using rxdatasources: Sensitivity depends on the nature of the data within those applications. rxdatasources itself is not designed to handle sensitive data directly, but vulnerabilities could potentially be exploited in the context of a larger application.

QUESTIONS & ASSUMPTIONS

  • BUSINESS POSTURE

    • Question: What is the intended scope of usage for rxdatasources? Is it primarily for internal projects, open-source community use, or commercial applications?
    • Assumption: The library is intended for broad use in the iOS development community to improve developer productivity and code quality in various types of iOS applications.

  • SECURITY POSTURE

    • Question: Are there any existing security policies or vulnerability management processes in place for the rxdatasources project?
    • Assumption: Current security practices rely on open-source community review and standard GitHub security features. There is no formal security audit or dedicated security team for this project.
    • Question: Are there any automated security checks currently integrated into the CI/CD pipeline (e.g., SAST, dependency scanning)?
    • Assumption: No automated security checks are explicitly mentioned in the repository description or observed in typical open-source library setups.

  • DESIGN

    • Question: What is the expected deployment environment for applications using rxdatasources? Are they primarily targeting the App Store, enterprise distribution, or other channels?
    • Assumption: Applications using rxdatasources are expected to be deployed through standard iOS application distribution channels, including the App Store, TestFlight, and potentially enterprise distribution.
    • Question: Is there a roadmap for future development and maintenance of rxdatasources, including security updates and vulnerability patching?
    • Assumption: Maintenance and updates are driven by community contributions and the project maintainers' availability. Long-term security support depends on continued community engagement.
