Recent high profile security incidents illustrate that no institution or business is immune from cyber attack. A cyber attack on the White House in 2014 resulted in a partial shutdown of its email system. In a reported attempt to extort money from the ECB, email addresses and other user contact information were stolen in 2014. Confidential movie scripts and emails about staff and movie stars were released as part of the 2014 Sony hack. Already this year, the Carphone Warehouse security breach in early August and the more recent Ashley Madison hack have received extensive media coverage.
