U.S. President Donald Trump on Tuesday signed a bill that prohibits the use of Kaspersky Lab products and services in federal agencies.

The National Defense Authorization Act for FY2018 (H.R. 2810) focuses on Department of Defense and Department of Energy programs, authorizes recruitment and retention bonuses for the Armed Forces, and makes changes to national security and foreign affairs programs.

Section 1634 of the bill bans the use of products and services provided by Russia-based cybersecurity firm Kaspersky Lab. The prohibition will go into effect on October 1, 2018.
