What does Software Composition Analysis (SCA) primarily identify?

Software Composition Analysis (SCA) is primarily focused on identifying open-source and third-party libraries that are used within an application. This process is critical for understanding the components that comprise a software project, especially considering the dependencies that come from various sources in today's software development landscapes.

By utilizing SCA, organizations can inventory these components, evaluate their licenses, and assess known vulnerabilities associated with them. This is particularly relevant because many applications rely heavily on open-source libraries, which can introduce security risks if not properly managed. SCA allows developers and security teams to ensure compliance with licensing and to proactively address any vulnerabilities in the libraries being used.

The other options relate to different aspects of software security and development but do not encompass the primary focus of SCA. File permission issues pertain to security configurations, architecture involves the structural design of the application, and network traffic patterns are relevant for monitoring and analyzing network behavior rather than the composition of software itself.
