BUSINESS POSTURE

  • Business Priorities and Goals:

    • Priority: Simplify Core Data usage in iOS and macOS applications.
    • Goal: Provide a more developer-friendly and less verbose API for common Core Data operations, reducing boilerplate code and improving developer productivity.
    • Goal: Enhance code readability and maintainability for projects using Core Data.
    • Goal: Offer a robust and reliable abstraction layer over Core Data, handling common tasks and edge cases.

  • Business Risks:

    • Business Risk: Adoption risk - If the library is not widely adopted, the effort invested in development and maintenance might not be justified in terms of community impact.
    • Business Risk: Maintenance risk - As an open-source project, reliance on community contributions for ongoing maintenance and bug fixes can be a risk if community engagement declines.
    • Business Risk: Compatibility risk - Changes in Apple's Core Data framework or operating systems could break compatibility and require significant updates to the library.
    • Business Risk: Security vulnerability risk - Security flaws in the library could be exploited by malicious actors in applications that use it, potentially leading to data breaches or other security incidents. This risk is amplified by the library's role in data persistence.
    • Business Risk: Dependency risk - Applications using this library become dependent on it. Issues with the library can directly impact the functionality and stability of dependent applications.

SECURITY POSTURE

  • Existing Security Controls:

    • security control: Code review - Open-source nature allows for community code review, increasing the chance of identifying and fixing potential security vulnerabilities. Implemented through GitHub pull requests and community contributions.
    • security control: Static analysis - Developers likely use Xcode's built-in static analyzer and potentially other third-party static analysis tools during development. Implemented locally by developers during development.
    • security control: Dependency management - Uses standard dependency management tools like CocoaPods or Swift Package Manager, which provide some level of dependency integrity checks. Implemented through dependency managers configuration and processes.
    • accepted risk: Limited dedicated security testing - As an open-source project, dedicated security testing might be limited and rely on community contributions and general development practices.
    • accepted risk: Vulnerability disclosure process - The project likely relies on standard GitHub issue reporting for vulnerability disclosure, which might not be as structured as dedicated security vulnerability programs in larger organizations.

  • Recommended Security Controls:

    • security control: Automated security scanning - Integrate automated security scanning tools (SAST, DAST, dependency scanning) into the CI/CD pipeline to proactively identify vulnerabilities.
    • security control: Security focused code review - Encourage security-focused code reviews, specifically looking for common vulnerability patterns in data handling and Core Data interactions.
    • security control: Vulnerability disclosure policy - Establish a clear vulnerability disclosure policy to guide security researchers and users on how to report security issues responsibly.
    • security control: Regular dependency updates - Implement a process for regularly updating dependencies to patch known vulnerabilities in third-party libraries.

  • Security Requirements:

    • Authentication: Not directly applicable to a library. Authentication is handled by the applications that use this library. However, the library should not introduce vulnerabilities that could bypass application-level authentication.
    • Authorization: Not directly applicable to a library. Authorization is handled by the applications that use this library. The library should correctly handle data access permissions as defined by Core Data and the application logic.
    • Input Validation: Important. The library should handle data inputs safely and prevent common injection vulnerabilities (though less likely in the context of Core Data compared to SQL databases, but still relevant for data transformations and queries). Input validation should be implemented within the library where it processes external data or user inputs.
    • Cryptography: Potentially relevant if the library handles sensitive data that needs to be encrypted at rest or in transit. Core Data itself offers encryption options, and the library should not weaken or bypass these. If the library introduces new data handling features, consider if cryptographic measures are needed.

  • Build Process Description:

    • Developer makes code changes and commits them to a version control system (GitHub).
    • Changes are pushed to a central repository, triggering the CI system (e.g., GitHub Actions, Jenkins).
    • The CI system automatically builds the library, runs unit tests, and performs static analysis and security scans (SAST, dependency vulnerability checks).
    • If build, tests, and security checks pass, the CI system packages the library into distributable formats (e.g., CocoaPod, Swift Package Manager package).
    • The packaged artifacts are published to a package registry (like CocoaPods repository or Swift Package Manager registry) for developers to consume.

  • Build Process Security Controls:

    • security control: Version control - Using Git and GitHub to track code changes, manage branches, and facilitate code review. Implemented via GitHub.
    • security control: CI/CD automation - Automating the build, test, and security scanning process to ensure consistency and reduce manual errors. Implemented via CI system (GitHub Actions, Jenkins).
    • security control: Static Application Security Testing (SAST) - Automated SAST tools to scan the codebase for potential security vulnerabilities during the build process. Implemented within CI pipeline.
    • security control: Dependency scanning - Automated scanning of dependencies to identify known vulnerabilities in third-party libraries. Implemented within CI pipeline.
    • security control: Build environment security - Secure and hardened build environment to prevent build-time attacks and ensure integrity of build artifacts. Implemented by CI infrastructure and configuration.
    • security control: Code signing - Signing the released artifacts to ensure authenticity and integrity. (Potentially applicable for some distribution methods). Implemented during packaging and publishing steps.
    • security control: Access control to CI/CD system - Restricting access to the CI/CD system to authorized personnel to prevent unauthorized modifications to the build process. Implemented by CI system access management.

RISK ASSESSMENT

  • Critical Business Processes:

    • Critical Business Process: Development of iOS/macOS applications that rely on Core Data for data persistence.
    • Critical Business Process: Maintaining the integrity and reliability of application data managed by Core Data in applications using MagicalRecord.
    • Critical Business Process: Ensuring developer productivity and efficiency when working with Core Data.

  • Data to Protect and Sensitivity:

    • Data: Source code of the MagicalRecord library. Sensitivity: Moderate. Confidentiality is less critical for open-source, but integrity and availability are important.
    • Data: Build artifacts (library packages). Sensitivity: Moderate. Integrity and availability are important to prevent supply chain attacks.
    • Data: Application data managed by applications using MagicalRecord. Sensitivity: Varies depending on the application. Could be highly sensitive (user personal data, financial data, etc.). The library should not compromise the confidentiality, integrity, or availability of this data.
