Gen. Jim Mattis, the former secretary of defense during the start of the Trump administration, made a special appearance Wednesday at DefenseTalks. And while he touched on a number of things, from leadership to politics and the military’s adoption of emerging technology, he made some pretty critical comments about the state of the nation amid the upcoming election and its vulnerability to influence operations from key adversaries like Russia and China. Mattis said that while election systems and voting infrastructure are perhaps the most secure they’ve ever been against cyberattacks, the bigger problem is influence operations, calling the U.S. the most vulnerable he’s ever seen it in his lifetime to foreign influence and a lucrative target. During the on-stage interview, Mattis also touched on the nation’s cyber defenses, throwing water on the idea from some to form an independent U.S. military cyber service for foreign operations. However, he did call for a new model to protect the homeland’s critical infrastructure from cyber attacks, namely by sharing some of the resources housed within the U.S. military and NSA with DHS in emergency scenarios. But, Mattis said because the military doesn’t have authority to issue orders over matters happening within the U.S. and its infrastructure, there would need to be a civilian law enforcement leader — he proposed the FBI — who would step in to lead response to a major cyberattack on the homeland.
