CISA guide says OSS can be as secure as proprietary
On July 30, 2026 CISA published “Open Source Software: Security Principles and Practices,” a guide that says open‑source code can be just as secure as closed‑source if agencies apply rigorous risk‑management, vulnerability tracking, SBOMs, and the new C4 trust‑assessment framework. It gives concrete steps for the full OSS lifecycle, helping federal and private teams avoid false‑security myths.
