The cyberattack on Anthem, one of the nation's largest health insurers, points to the vulnerability of health care companies, which security specialists say are behind other industries in protecting sensitive personal information.

Experts said the information was vulnerable because Anthem did not take steps, like protecting the data in its computers though encryption, in the same way it protected medical information that was sent or shared outside of the database.

The hackers gained access to up to 80 million records that included Social Security numbers, birthdays, addresses, email and employment information and income data for customers and employees, including its own chief executive.
