Detection of security flaws

SCA tools are primarily focused on detecting vulnerabilities in open source and third-party components. However, it’s important to understand that while SCA tools are a crucial part of the software security landscape, they specifically cater to the threats posed by the reuse of external components. Here’s a deeper dive into how SCA tools detect security flaws:

• Open source databases and repositories: SCA tools continuously monitor and pull data from popular vulnerability databases such as the NVD, as well as other sources such as security advisories, mailing lists, or even GitHub repositories.
• Dependency analysis: SCA tools analyze the list of dependencies used in an application. This includes both direct dependencies (the ones you include explicitly) and transitive dependencies (dependencies of your dependencies).
• Version checking: Once the tool knows which components and versions are being used, it checks them against its database...
