What is software composition analysis (SCA) and why it matters?

• A. It analyzes third-party components and licenses to identify vulnerable or outdated dependencies, reducing supply chain risk.
• B. It scans code for syntax errors.
• C. It monitors user behavior for anomalies.
• D. It replaces all dependencies with in-house code.

Answer: (A)

Software composition analysis examines everything that makes up the software, focusing on third-party and open-source components, along with their licenses and versions. This matters because applications often rely on external code that can harbor known vulnerabilities, be outdated, or have license terms that create compliance risks. By mapping each component to security advisories and license data, teams can prioritize patching, replacing risky elements, and maintaining a thorough software bill of materials. This helps reduce supply chain risk and improves governance and compliance. It’s not about checking syntax errors, monitoring user behavior, or automatically replacing all dependencies with in-house code.
