According to a recent study by IBM and Sophos, U.S. data breaches cost an average of $8.19 million. That's more than double the worldwide average. The costs of a data breach are especially devastating to small businesses, but too many organizations wait to do something until it's too late. In this week's collection of cyber breach news stories from across the country, we look the Capitol One breach, as well as cyberattacks on a museum in San Francisco, a school district in Nevada and a radio station in Florida. We also provide an update on the 2017 Equifax security incident, which recently resulted in the biggest data breach fine of all time.
