Matthew Travis, Deputy Director of CISA, gave a presentation on countering foreign influence at an OECD high-level risk forum in December 2019. The presentation discussed the goals of election interference, how ideas spread and influence audiences, and the themes used in Russian disinformation during the 2016 US election, such as black issues, police brutality, immigration, and gun rights. Travis then outlined CISA's approach to quantify message impact, inoculate audiences, mitigate influence campaigns, and identify adversary tactics. The presentation concluded with recommendations for recognizing the risk of disinformation, securing systems, coordinating with social media, avoiding amplifying false information, and reporting incidents.
