SCA is a method for managing and securing open-source software components within a codebase. It involves identifying and inventorying open-source components to understand the risks associated with their use, such as licensing issues, outdated versions, and potential security vulnerabilities.

SCA tools can automatically scan a software codebase and detect all open-source components, including direct and indirect dependencies. They match these components against known vulnerability databases, licensing databases, and version histories to provide a comprehensive risk profile for the open-source usage within a given application.

This process helps organizations to maintain the compliance, security, and quality of their software products. It is a crucial part of modern software development processes, especially in environments that heavily utilize open-source components

SCA allows organizations to:

• Identify and track the use of open-source software within their code.
• Understand the potential security, licensing, and maintenance risks associated with each component.
• Take appropriate action to mitigate those risks, whether that’s updating to a newer version, replacing a problematic component, or addressing a security vulnerability.

How is Software Composition Analysis (SCA) performed?

SCA is performed through a systematic process which generally involves the following steps:

1. Inventory Creation: The first step in SCA involves scanning the software codebase and creating an inventory of all open-source components. This includes libraries and other third-party components, along with their respective versions. The inventory should also include dependencies since these may also bring in open-source components with their own risks.
2. Vulnerability Analysis: Once the inventory is complete, each component is checked against vulnerability databases like the National Vulnerability Database (NVD) or proprietary vulnerability databases maintained by SCA tool vendors. These databases contain lists of known security vulnerabilities along with the software versions they affect.
3. License Compliance Checking: SCA tools also analyze the license associated with each open-source component. This is critical to ensure compliance with the terms of use for each component. For example, some licenses may require attribution, while others may mandate that any derivative work also be open source.
4. Version Checking: It’s important to know whether the components in use are up to date. Using outdated versions may expose the software to vulnerabilities that have been patched in later versions. It may also mean missing out on improvements or features.
5. Policy Enforcement: Organizations often have policies regarding the use of open-source software, such as which licenses are acceptable or what level of vulnerability risk is acceptable. SCA can enforce these policies by flagging violations for review.
6. Reporting and Remediation: After analysis, the SCA tool typically produces a report detailing all the findings. If potential issues are identified, the team can then decide on the appropriate remediation steps. This could include updating a component to a newer version, replacing it with an alternative, or potentially even rearchitecting the software if a critical issue is identified.

By utilizing SCA, organizations can better manage the risks associated with using open-source components, ensuring that they reap the benefits of open source while mitigating potential legal and security risks.
