Open Source Software

Open Source Software Security

Open source software is part of the foundation of the digital infrastructure we all rely upon.
Find out here how CISA is working to help secure it.

Open source software is widely used across the federal government and every critical infrastructure sector. As America’s Cyber Defense Agency, CISA works to understand and reduce cyber threats to the federal government and critical infrastructure. Ensuring secure open source software is a critical part of this effort.

CISA’s Open Source Software Security Roadmap establishes CISA’s role in helping to secure open source software by aligning it with CISA’s mission to identify and reduce risks to the federal government and critical infrastructure. In turn, CISA’s efforts will contribute to the improved security of the broader open source ecosystem.

CISA has several ongoing initiatives around open source security, including our community-driven work around software bill of materials (SBOM). We also actively contribute by open sourcing much of our code via our “open-by-default” software development policy.
