Build Process Security Framework for Recursive Compliance Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software systems face challenges in efficiently verifying the compliance of third-party software with security framework levels, such as SLSA, due to the complexity of evaluating build and dependency vulnerabilities across diverse software components.
Innovation Solution
A method and system that analyze build files and dependencies using a framework that maps security framework requirements to predicates, applies system-specific implementations, and generates a report on compliance, allowing for recursive evaluation of dependencies.

1Measurement precision
If a framework maps security requirements to predicates and evaluates build files recursively, then measurement precision of security compliance is improved, but device complexity increases
Solution Approach 1:
The security framework is segmented into distinct components: requirement definitions, predicate mappings, system-specific implementations, and recursive evaluation functions. Each component handles a specific aspect of security verification, allowing complex security checks to be broken down into manageable, independent modules that can be developed and maintained separately.
Solution Approach 2:
Predicates serve as intermediaries between security requirements and system-specific implementations. The predicate layer abstracts the complex mapping logic, providing a standardized interface that connects high-level security requirements with diverse build system implementations without requiring direct coupling between them.
2Reliability
If the framework recursively evaluates all dependencies and build files, then reliability of security assessment is improved, but loss of time increases
Solution Approach 1:
The framework performs preliminary actions by caching evaluation results for previously analyzed build files and dependencies. When the same dependency is encountered during recursive evaluation, the cached results are reused instead of re-evaluating, significantly reducing redundant computation time while maintaining complete security coverage.
Solution Approach 2:
The evaluation framework implements a nested structure where the main evaluation function contains recursive calls to evaluate dependencies, which in turn contain their own nested evaluation loops. This nested architecture allows the system to systematically traverse the entire dependency tree while maintaining a unified evaluation context and enabling efficient result propagation through the nested levels.

AI summary
A method includes receiving multiple security framework requirements, mapping the security framework requirements to a predicate, mapping the predicate to a system-specific implementation, evaluating, using a runtime system, the target system by analyzing a multitude of build files using the system-specific implementation, and presenting a report indicating whether the security framework requirements are satisfied.
