Securing Open Source Software Act of 2023

This bill requires the Director of the Cybersecurity and Infrastructure Security Agency (CISA) to develop a framework for assessing risks in open source software components used by federal agencies. It mandates annual assessments of critical open source software, considering factors like security practices, deployment scope, and community health, and requires public sharing of results and tools. The law directly affects federal agencies (which must use these assessments) and the open source software community (which must be consulted in framework development). Key provisions include publishing risk frameworks, automating assessments, and conducting a study on extending assessments to critical infrastructure sectors.
