On Thursday, the House Intelligence Committee approved a spending bill to fund the National Security Agency and other intelligence organizations. Included in the bill is a provision that would set aside $75 million for the NSA to improve its internal security and mitigate insider threats to classified material. In other words, the bill seeks to prevent future Edward Snowdens.

Earlier this month, the Senate Intelligence Committee advanced its own bill authorizing funding for the NSA and its surveillance programs. The bill also provides additional money for countering insider threats, but it includes protections for "legitimate" whistle blowers, the Hill's Brendan Sasso reported.

The NSA had previously deployed security software that was intended to prevent insider threats, according to an October Reuters report. However, the software, purchased from Raytheon, was allegedly not installed at the Hawaii station Snowden worked at due to the limitations of the station's network connection back to the continental US.
