Government funding for a program that hunts for threats on America's critical infrastructure networks expired on Sunday, preventing Lawrence Livermore National Laboratory from analyzing activity that could indicate a cyberattack, the program director told Congress on Tuesday. From a report: Nate Gleason leads a team at Lawrence Livermore National Laboratory (LLNL) focused on nation-state threats against critical infrastructure, and this includes the CyberSentry Program.
