The Best Practices badge is a way for Free/Libre and Open Source Software (FLOSS) projects to show that they follow best practices. 

Projects having a CII badge will showcase the project’s commitment to security. Examples of initial criteria include basic open source development practices (website, open source license, and user engagement), use of change control tools, attention to quality (automated test suite), and focus on security (secure project delivery method, use of dynamic and static analysis tools, as appropriate for the project). Consumers of the badge will be able to quickly assess which open source projects care about security-conscious development. 

The Core Infrastructure Initiative is a multi-million dollar project to fund and support critical elements of the global information infrastructure. It is organized by The Linux Foundation and enables technology companies to collaboratively identify and fund open source projects that are in need of assistance, while allowing the developers to continue their work under the community norms that have made open source so successful.

The Linux Foundation supports the creation of sustainable open source ecosystems by providing financial and intellectual resources, infrastructure, services, events, and training
