#APPLICATION SECURITY TESTING

Software Composition Analysis (SCA)

Software Composition Analysis (SCA) is a critical process in modern software development, designed to manage and secure the open-source components and third-party libraries used in your applications.

  • What is SCA?
Software Composition Analysis (SCA) is a method of identifying and managing the open-source components and third-party libraries used in an application. SCA tools analyze the composition of software, detecting the presence of known vulnerabilities, outdated versions, and licensing conflicts. By providing a clear overview of all components within the software, SCA helps developers and security teams ensure that the application is secure and compliant with industry standards and regulations.

  • How SCA Works?
SCA operates by scanning the codebase and build artifacts to identify all open-source components and third-party libraries. It then cross-references these components with known vulnerability databases and license repositories. The process typically involves the following steps:

Component Identification

The SCA tool scans the entire codebase, identifying all open-source and third-party components, including direct and transitive dependencies.

Vulnerability Matching

It then matches these components against a comprehensive database of known vulnerabilities, such as the National Vulnerability Database (NVD), to detect any security risks associated with the components.

License Analysis

SCA also checks the licenses of all identified components to ensure compliance with the organization’s licensing policies, flagging any potential legal issues.

Version Management

The tool tracks the versions of all components and alerts the team if any are outdated or if there are available patches that could mitigate security risks.

Reporting and Remediation

After the analysis, SCA generates detailed reports that include the vulnerabilities found, their severity, license issues, and recommendations for updating or replacing insecure components.

  • Use Case​
SCA is particularly valuable for organizations that rely heavily on open-source components and third-party libraries in their software development. A common use case is during the integration and testing phases of the development lifecycle, where SCA ensures that all components are up-to-date and free of known vulnerabilities before the software is released. It is also essential for maintaining long-term application security, as SCA can be integrated into CI/CD pipelines to provide continuous monitoring of dependencies, ensuring that new vulnerabilities are promptly addressed. This is especially important for industries with stringent compliance requirements, such as finance, healthcare, and government sectors, where the use of open-source software must be carefully managed.
