The Federal Acquisition Security Council Improvement Act of 2026 aims to bolster the security of federal procurement processes by addressing risks associated with acquiring goods and services that may pose national security threats, particularly from foreign adversaries. This legislation seeks to enhance the Federal Acquisition Security Council's capabilities, which is tasked with identifying and mitigating such risks. Key provisions include the introduction of new definitions for "source of concern" and "covered source of concern," clarifying what constitutes a national security risk.
