Defense contractors must now tell the Pentagon if foreign governments can see their code

The US military wants to buy products and services only from companies that disclose whether foreign governments can access their source code. This means defense contractors will have to reveal any agreements they have to share code with other countries.

The US military is trying to close a long-standing loophole. For years, defense contractors could sell systems to the Pentagon without revealing if they had also shared the underlying software code with foreign governments. This change means the Pentagon will now know if a foreign power has access to the digital blueprints of critical defense technology.
