Last week, Senator Mark Warner of Virginia addressed a crowd at the Center for New American Security (CNAS), offering what he called a “New Doctrine for Cyberwarfare & Information Operations.” Sen. Warner currently serves as the Vice Chairman of the Senate Select Committee on Intelligence. In that role, he helps to oversee that committee’s investigation into Russian interference in the 2016 election. To combat the sort of information warfare and cyberattacks used in that election, as well as the more general and staggering cybersecurity threats posed to U.S. persons and entities, the senator lays out a detailed series of recommendations for this doctrine, emphasizing: establishing international cyber norms and rules; combatting disinformation and misinformation; hardening networks, weapons systems, and Internet of Things devices; realigning defense spending; and strong federal leadership.
