Securing software is a priority for a functioning and thriving digital economy. Achieving sustainable and secure software, in particular open source software, is a shared effort, requiring a multi-faceted, long-term approach that includes tooling and resources, education, collaboration, and leadership! 

At the Linux Foundation, our projects and communities are shoring up software supply chain security in diverse, widespread, and comprehensive ways, and stewarding compliance with regulations such as the EU Cyber Resilience Act and the US Executive Order on Cybersecurity. To encourage project discovery and enhance collaboration, we’ve created LF Security, a central home where you can get the resources you need to improve your organization’s security posture, and to encourage more people to join us in our efforts.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             

LF Security brings together the myriad LF project communities, initiatives, resources, and infrastructure that each advance the security of software, including technical projects, standards and specifications, events and webinars, training and certification programs, research projects, and other tools and initiatives. We’re committed to growing widespread awareness of our security resources, and encourage all stakeholders to contribute time, talent, working capital, and other inputs as a means to sustaining them. 

If you’re new to open source, or a veteran of the community, LF Security is the place to find what you need to help secure open source software. And if you have a project to propose, want to contribute to our communities, or have other ideas to help us, we encourage you to get in touch!
