NASHVILLE, Tenn. (AP) — Tennessee was among the more than two-thirds of states rated as “high risk” for security problems related to its computers tapping into the federal health insurance exchange system.

Federal cybersecurity experts worried in advance of the Oct. 1 deadline for new insurance exchanges that state computer systems could become a backdoor for hackers and identity thieves. But the Obama administration says the issues have been resolved or addressed, and no successful cyberattacks have occurred.
