Minnesota Secretary of State Steve Simon says his office continues to track for cybersecurity threats every day leading up to November’s elections. He says fundamentally Minnesota is in good shape because of the use of a paper-based voting system that is hard to hack.

Simon says, however, that the bigger challenge is protecting centralized functions, such as the statewide voter registration system, which contains sensitive voter information. Russians attempted–and failed–to breach Minnesota’s voting system in 2016.
