TOPEKA, Kan. (AP) — Kansas has partnered with federal agencies to try and ensure the security of the state’s voter database, as the FBI investigates security breaches in other states.

Kansas director of elections Bryan Caskey says he participated in a conference call last week with the U.S. Department of Homeland Security and election officials from other states “about threats that had been collected at the national level concerning election systems.”

The Wichita Eagle reports that security breaches occurred earlier this summer in Arizona as well as in Illinois, when a hacker was able to see information on data about 200,000 registered voters.

According to Caskey, Kansas uses the same software vendor as Arizona for its voter database, but it has at least one significant layer of security above what Arizona has.
