Tim Roemer, Arizona's chief information security officer and homeland security director, talks about why cybersecurity isn't just an IT issue anymore.

Officials also renamed an information-sharing program between state agencies as the AZ-ISAC.

Tim Roemer will maintain his role as state CISO, making Arizona one of the few states to place cybersecurity under a homeland security agency rather than its IT organization.

Tim Roemer, who's worked in a variety of roles under Gov. Doug Ducey, is now the state's top cybersecurity official.
