What is SCA in Cybersecurity?
Software Composition Analysis.
Software Composition Analysis identifies open-source and third-party components in an application's codebase, then checks those components against databases of known vulnerabilities. SCA tools track dependency trees, flag outdated libraries, verify license compliance, and alert teams when new CVEs affect their software supply chain.
Why SCA Matters for Your Cybersecurity Career
Most applications contain 70-90% open-source code. SCA catches vulnerabilities in dependencies that SAST tools miss because they do not scan library internals. Security engineers integrate SCA into build pipelines to prevent vulnerable packages from reaching production. The Log4Shell incident demonstrated why monitoring third-party components is critical.
